Motion Control – Flexible Operating Tool

What do wasps have to do with brain surgery? At first glance, not a whole lot. However, one species serves as the model for an innovative brain surgery needle that is being developed by a team of researchers from England.

Fall River, MA — Motion Control Components Application – In tumor treatment, neurosurgeons today use a thin, rigid needle to inject medication into the affected brain tissue. This carries a relatively high risk of injuring healthy tissue, because a rigid needle only allows the surgeon to enter a certain region of the brain, following a straight path. The ideal solution would be a flexible operating tool.

Motion Control – Tutorial – When to Choose A 4pole DC Motor

January 17, 2023 Editor

Motion Control – Maxon’s 4pole DC Motors

Selecting a DC micromotor for use in applications from aerospace through to downhole drilling inspection, a 4pole motor has advantages. A 4pole design is stronger than a 2pole equivalent but can also fit within the same space and weight envelope.

Fall River, MA — Motion Control – For DC motor applications that require high torque in a light weight and compact space envelope, 4pole motors can be the optimum choice. A 4pole motor can fit within the same footprint as a 2pole design but they are able to generate more torque. Importantly, a 4pole motor is also stronger than a 2pole motor of equivalent size, meaning that it more closely maintains its speed when a load is applied.
