Motion Control – RVC-5 Rotational Voice Coil Motor- A New Standard for Rotational Voice Coil Stages!

Posted by Editor on December 23rd, 2011

Sunnyvale, CA, — Equipment Solutions, Inc. introduces the RVC-5 Rotational Voice Coil Motor, setting a new standard for rotational voice coil stages. It is an instrument with the extreme precision of a galvanometer and the compact size and reliability of a resonant scanner. The RVC-5 rotational voice coil motor creates “Rotational Translation” using a flexure bearing. The “Rotational Translation” is achieved by tilting a precision mirror +/- 5°. Developed using advanced FEA technology, this flexure bearing will provide infinite life, and perfectly smooth motion that is free of stiction and friction, and is capable of positioning a load with unprecedented speed and repeatability. Typical industrial, medical, and scientific applications include: Semiconductor fabrication, optical testing, scanning microscopy, circuit board assembly, micro manufacturing, laser cutting, engraving, drilling, and laser marking.

This very compact RVC-5 rotational voice coil motor measures just 25 mm (1.0 in.) wide x 40 mm(1.54 in.) long x 15 mm (0.61 in.) high and has fully integrated absolute angle position sensor electronics. The non-contact electro-optic sensor directly monitors the user load with micro-radian scale resolution and repeatability. This new voice coil motor stage can be commanded to oscillate or move to any fixed point in its angular range following a completely linear velocity move profile. Critical positioning specifications include: Sensor Non-Linearity ±0.3% FS, Sensor Scale Drift 200 PPM/°C, and Sensor Short Term Repeatability 1.5 µrand.

RVC-5 rotational voice coil motor can be supplied with Equipment Solutions, SCAB14 Servo Controlled Amplifier. Easy access mounting holes facilitate integration into new and existing applications and user loads are easily mounted to the rigid “H” frame lever arm.

Motion Control – Lower Cost Moving Magnet Designs from H2W Technologies!

Posted by Editor on December 22nd, 2011

Santa Clarita, CA —– Typically a Motion Control H2W Moving Magnet Actuator has precision bushings and shaft which cause the moving magnet design to be cost prohibitive. However not every customer requires a bushing with high tolerance precision, and thus H2W has the ability to modify the linear bearing systems of our voice coil designs to accommodate a lower cost bushing and shaft. The pictured actuator has a custom shaft and housing to accommodate a customer’s specific cost, envelope, and shaft requirements

Voice Coil Actuators are typically for applications requiring short strokes, however, H2W offers varying strokes from their stock actuators and can modify any of these models with a short lead time to accommodate many specification modifications. Additionally, typically voice coil actuators have been intended for low force applications, however H2W Technologies offers forces up to and exceeding 100 pounds of continuous force and 300 pounds of peak force at 10% Duty Cycle.

The moving magnet style actuator is provided with supplied internal bushings and a hardened steel shaft or hard anodized aluminum shaft.

Welcome to the Kollmorgen “Engineer’s Library”

Here you’ll find motion control technical white papers, best practices and other resources to help you envision, design and realize a truly differentiated machine. We’ll be updating the Engineer’s Library several times per year, so check in often.

Achieve Superior Servo Performance, Quickly, with Auto-Tuning!

Motion Control - Kollmorgen's Engineering Library

RADFORD, VA — Compliance in motion control transmission components tends to decouple the load’s inertia from the servo system at higher frequencies. First-generation auto-tuners didn’t take this “rubber band effect” into account, and even the best tuning specialists need lots of time and a little luck to get optimum performance. Kollmorgen’s chief engineer of servo technology, George Ellis, explains how full-frequency auto-tuning can achieve perfect performance in a matter of minutes.

Motion Control – One-Two-Go! Startup Made Easy. Learn About User-friendly Drive Technology From Maxon

Posted by Editor on December 5th, 2011

Maxon-Motion Control Escon36-2-DC PWM Controller

Fall River, MA — The ESCON 36/2 DC is the first product in the new servo controller range by maxon motor and shows how user-friendly drive technology can be. The extremely compact, powerful 4-quadrant PWM servo controller offers efficient control of brushed permanent-magnet activated DC motors up to approx. 72 W. With its unsurpassed power density, it is the embodiment of the degree of miniaturization that is currently possible in the field of servo controller technology. It is hardly possible to pack more power, more functionality, more convenience and more protection in such small dimensions with today’s level of technology.

The ESCON 36/2 DC has excellent control properties and a very fast digital current controller with an enormous bandwidth for optimal motor current/torque control. The drift-free yet extremely dynamic speed behavior enables a speed range of 1 to 150,000 rpm. The little miracle provides a wide range of functions, with fully configurable digital and analog inputs and outputs. It is perfectly matched to maxon’s range of motors and thus allows dynamic drive solutions that meet the highest demands. Furthermore it can be run in various operating modes (speed controller (closed loop), speed controller (open loop), current controller).

The ultra-compact servo controller is controlled by means of an analog set value. This value can be specified by means of analog voltage, an external or internal potentiometer, a defined value or by means of a PWM signal with variable duty cycle. Other interesting functions are for instance the ability to enable or disable the power stage depending on the direction of rotation, or to use speed ramps for acceleration and deceleration. The speed can be regulated by means of a digital incremental encoder (2-channel, with/without line driver), DC tacho or without encoder (IxR compensation).

Startup made easy

Top performance should not be a matter of practice makes perfect. Therefore the servo controller has been designed specifically with easy startup and user-friendliness in mind – no in-depth knowledge of drive technology is required. When the servo controller is connected to a PC via a USB port, it can easily and efficiently be configured with the “ESCON Studio” graphical user interface. During startup and configuration of the inputs and outputs, monitoring, data recording and diagnostics, the user has access to a large variety of functions and is assisted by user-friendly software wizards, as well as a well-designed automatic procedure for fine-tuning the controller. On the hardware side, the ESCON 36/2 DC comes fully equipped with everything that is needed. For example, no additional external filters or motor chokes are required and pre-assembled cables for the startup are available as accessories.

Top-notch protection

The ESCON 36/2 DC has protective circuits against overcurrent, excess temperature, under- and over-voltage, against voltage transients and against short-circuits in the motor cable. Furthermore it is equipped with protected digital inputs and outputs and an adjustable current limitation for protecting the motor and the load. The motor current and the actual speed of the motor shaft can be monitored by means of the analog output voltage.

No-compromise flexibility and efficiency

The large range for the input voltage and the operating temperature allows flexible use in almost all drive applications, in automation technology, in small machine manufacturing and equipment engineering, and in mechatronics. With its exceptional efficiency of 95%, the inexpensive ESCON 36/2 DC is a first-class choice for mobile, highly efficient yet consumption-optimized applications.

Motion Control – New in USA! Powerlink for JVL Integrated Servo Motors!

Posted by Editor on November 22nd, 2011

Birkerød, Denmark and Morrow, OH (USA) — JVL has for many years been one of the leading companies in the field of integrated motion control servo- and stepper motors. JVL has set the goal of being the world leader in industrial Ethernet for integrated motors with the widest range of Industrial Ethernet communications for the range of JVL Integrated Servo and Stepper motors. In recent years, JVL has gained a high level of know-how and technological expertise and can now present a very smart way of using several Ethernet communications with only one expansion module.

JVL now presents POWERLINK Industrial Ethernet protocols for its complete range of integrated servo motors. The POWERLINK protocol was originally developed by the Austrian company B&R for use with their PLCs, but can also be used by other suppliers that use the POWERLINK interface.

Last year JVL introduced EtherCAT and EtherNet/IP modules. Profinet and SERCOS III are under development so all important Industrial Ethernet protocols will soon be available

The Industrial Ethernet module from JVL fits into the complete range of integrated servo motors from 50 W to 3000 W, and is a versatile module which has the ability to be upgraded with other protocols or newer versions of the same protocol at any time. Because of the upgradeability, the JVL Industrial Ethernet module is also ‘future proof’ as newer versions of the protocols will always fit into the design.

The JVL Ethernet POWERLINK module is equipped with 2 Ethernet connectors and a built-in hub, enabling line topology without any extra (expensive) hardware. The JVL Ethernet POWERLINK module has several LEDs, enabling technicians and operators to get a quick status overview. There are also opto-isolated digital I/Os embedded in the module, enabling control of extra sensors etc without external I/O modules. This minimizes the number of devices on the net and also reduces cable costs.

All connectors are rugged M12 connectors suitable for the rough conditions in industrial environments.

Furthermore, all registers in the JVL MAC motor are accessible via the Ethernet POWERLINK connection, thereby enabling complete control of motor configuration and motion.

The JVL Ethernet POWERLINK module is very easy to use and configure via a predefined setup, and is easy to alter using the JVL MacTalk application software.

New From Servo2Go – Maxon’s New Downhole Drilling Brushless Servo Motor!

Posted by Editor on November 18th, 2011

Greenville, DE – Drive systems made by maxon do their job under the most difficult conditions, such as, for example, on Mars. But not only in high altitudes or in outer space, maxon DC motors also operate in harsh ambient conditions as encountered deep underneath the earth’s surface – immaculate, dependable, efficient.

As the first manufacturer worldwide, maxon motor launches with its EC 22 HD (Heavy Duty) a standard motor for extremely harsh operating conditions. Developed for the exceptionally high requirements in deep drilling technology, the electronically commutated motor EC 22 HD resists even most extreme conditions in which “normal” drives call it quits.

Deep drilling (in the oil and gas exploration industry called “Downhole Drilling”) permits exploration of oil and gas resources from depths beyond 2’500 meters (8’200 feet). In conjunction with directional drilling (the dynamic orientation of a borehole), it allows exploration of, so far, inaccessible deposits in drilling depths of currently about 5’000 meters (16’500 feet) and bore lengths of up to 11’000 meters (36’000 feet). Today, electronics and the respective drives permit more sophisticated monitoring and control in a multitude of functions within the drilling process. For instance, the drilling head’s position and orientation can be dynamically measured and adjusted. Or; in various deep drilling tools, hydraulic valves and flaps are being operated by electromechanic drives. Temperature and pressure conditions present in this depth range, in conjunction with high vibration emitted by the drilling process, make the employment of electric drives a real challenge.

The different variants of the EC 22 HD are designed for operation in air or submerged in oil (flooded in hydraulic fluid. Their assigned power rating depends on the surrounding medium and averages to 80 Watts in air and, due to remarkably higher heat dissipation, 240 Watts in oil. They are designed to cope with ambient temperatures of more than 200°C (390°F) and atmospheric pressures of up to 1’700 bar (25’000 psi). Further requirements of the 22 mm diameter motors are the capability to withstand vibration of up to 25 grms as well as impulse and impact of up to 100 G, that is 100 times gravitational acceleration – as a parallel; a Formula 1 race car encounters about 2 G, a fighter jet about 13 G. The motors feature high efficiency (in air up to 88%, in oil more than 70%) and therefore offer the best prerequisites for battery-operated applications. With their detent-free running characteristics, they possess outstanding regulation behavior and are especially suitable for high-precision positioning tasks, even at low speed. .

The motor unveils new possibilities in a number of applications that call for equally high requirements. It is well-prepared for the utilization in space technology or in power plants as well as in vehicle manufacturing, in the aircraft industry, in mining or in highly dynamic movements.

An optional 4000 count encoder, integrated into the motor housing, provides stall detection and stall prevention. Applied Motion’s proprietary stall prevention algorithm monitors rotor lag and automatically reduces speed and acceleration to avoid motor stalls, allowing 100% torque utilization.
