Vaughan, Ontario, Canada — Motion Control Components — JVL presents a new innovative closed-loop stepper motor technology for its NEMA 23 & 34 integrated stepper motor range from 0,1 to 12 Nm. JVL, the European leader in the development of integrated servo and stepper motor technology, has now again developed a new and unique product in the field of integrated motor control.

New Innovative Technology

JVL closed-loop integrated stepper motors, QuickStep®, provide higher torque, faster acceleration, torque control, stall free operation and quieter movements than traditional step motor systems. QuickStep do this with greater efficiency and less motor heating because motor phase current are regulated up and down according to need. Performance of JVL closed-loop steppers are similar to servo motors, but with higher torque and often without need of gearbox, resulting in a more inexpensive solution. Design safety factors have always been high for stepper motors to ensure stall-free operation – now with QuickStep closed-loop control design can be very close to the limit resulting in even lower costs. QuickStep is a true closed-loop control system that compensates step angle errors during a movement and correct errors within a full step. If load becomes too high speed is lowered and position errors will always stay within two full-steps. Smart digital design and very high update rates (36 MHz) means there is no need of any manual adjustment or setup. It works like a perfect stepper motor benefitting from the servo motor technology.

Advantages compared to open loop stepper motors

  • Position feedback and control
  • Fast and easy commissioning. No tuning needed
  • No stalling. No step losses at all
  • Torque control
  • Much faster positioning and more cycles per second
  • Increased efficiency and thereby much lower temperature
  • Shorter settling time
  • Controls higher inertias than open loop steppers
  • Higher load tolerance
  • More quiet operation (lower acoustic noise)
  • Longer lifetime due to lower temperature
  • Correct positioning without overshoot and oscillation

Advantages compared to servo motors

  • Very high Torque at low speed. Often 3-4 times higher in same motor flange size
  • Very high ratio-of-inertia, often up to 40:1
  • Faster commissioning. No tuning needed
  • Lower price. Same price as open loop steppers
  • Totally stiff at standstill. Full holding torque
  • Direct drive without gearbox (better and more precise torque control)
  • Correct positioning without overshoot
  • No oscillation
  • Very short settling time

Benefit in these application from closed-loop stepper motors

  • Multiple axis applications (RS485, CANopen)
  • Industrial Ethernet: Profinet, EtherNet/IP, EtherCAT, Powerlink, Modbus TCP, SERCOS III
  • Magnetic or Absolute Encoder Feedback
  • Positioning tasks with load changes
  • Applications that require quiet operation, short settling times and precision positioning

Applications include

  • Winding applications
  • Belt drives (start/stop, positioning)
  • Dosing pumps and filler systems
  • Semi-conductor mounting
  • Wafer production
  • Textile machines and industrial sewing machines
  • Robotics
  • Testing and inspection systems

Motion Control Integrated Stepper Motor with EtherNet Available from Servo2Go!

Greenville, DE – Motion Control Components –  Servo2Go is pleased to offerf eight motion control integrated drive+motors from Applied Motion Products to our line of Ethernet and EtherNet/IP motion control products

The STM23 models fuse a high performance motion controller with 100 MBit Ethernet communications to a high torque NEMA23 step motor. Connecting to an Allen-Bradley ControlLogix, CompactLogix or MicroLogix PLC? EtherNet/IP is also available

Servo2Go-Logo

The STM23Q-2Ex provides 125 ounce inches of torque, while the longer STM23Q-3Ex produces 210 ounce inches. Both models are available with an optional 4000 count/rev optical encoder, safely housed inside, that can detect and prevent motor stalls using Applied Motion’s proprietary stall prevention algorithm. Our auto tuned digital current control provides smooth, quiet motion, while an advanced anti-resonance algorithm with electronic damping allows for maximum torque utilization, rapid acceleration, and fast settling times

Software applications can communicate with the STM23 in real time, using the SCL and Q languages over standard 100 megabit Ethernet cabling, addressing and protocols. Ethernet can transmit data at 100 times the speed of CANopen and more than 1000 times faster than RS-232 and RS-485. The number and types of devices that can share a network are practically unlimited.

Even if you are just programming a Q drive for standalone operation, the Ethernet option can be more convenient than chasing down a USB-serial converter and trying to remember which COM port it uses. Just plug the drive into your office network, install our free, easy to use software, and you’re ready for programming and configuration.

50 piece pricing begins at $371 US/ea. Delivery is 1-2 weeks.
