maxon motor high-power brushless DC motor

A 14-pole, high-torque, 40 mm brushless DC inner rotor motor has been released by maxon motor.

It can produce continuous torque levels of 232 mNm at over 7000 rpm. The 100 W version brings the line of multipole brushless motors a third power option, along with the existing 50 and 70 W versions.

There are 9, 18, 36 and 48 V nominal DC windings available. The 50 and 70 W motors have a maximum speed of 10,000 rpm and the 100 W motor has a maximum speed of 8000 rpm. It is possible to use the speed constant of the motor (commonly known as Kv) to configure the motor for the speed requirement of the motor’s application. For example, using the 18 V winding of the 70 W motor and a system voltage of 24 V, the motor will have a no-load running speed of just over 10,000 rpm. This speed can then be controlled with one of maxon’s brushless DC servo amplifiers.

The motors are available with tiny high-resolution encoders and compact planetary gears. Services from maxon motor Australia are available to help with the configuration of motor, gearhead, encoder and control units to suit the specific needs of the application.
