New 30mm DC servo motor with Precious Metal Brushes.

At the pinnacle of maxon motors permanent magnet direct current (PMDC) lies the RE series of servomotors that utilise high power Rare Earth magnets and maxon’s patented ironless rotors. maxon today release the new RE30 motor.

The New RE30 DC motor has been created after extensive research and development. maxon engineers were set with the task of creating a small DC servo motor with the smoothest possible characteristics. This specific requirement comes from the ultra-sensitive tactile haptic feedback.  Precious metal brushes within a DC motor are a commutation method that offers the lowest brush contact resistance over the entire motor service life. Low contact resistance is also a characteristic that assists with smooth, subtle and accurate control over the motor. The new RE30 precious metal brush motor starts rotation at very low voltages even after long periods at standstill or stall. By comparison with maxon’s  existing 25mm motor the new 30mm motor has twice the power and only a small increase  in the diameter that is still comfortable when mounted in a gripper or joystick. The precious metal commutation system delivers minimal amounts of high frequency interference commonly referred to as commutation noise. Combining precious metal brushes with a very low inertia ironless winding that has no detent positions or cogging allows the motor to be used as an extremely sensitive sensor transmitting forces emulating even the lightest touch.

The development of this motor was initialised by maxon customers. As a result, the motor is specifically designed for haptic applications such as surgical robots. This means the motor can also be used as a highly-sensitive sensor, acting as the sense of touch for registering mechanical resistance.
