maxon motor 40 mm brushless DC inner-rotor motor

maxon motor has released its 14-pole, high-torque, 40 mm brushless DC inner-rotor motor. With dimensions of 40 x 56 mm, the motor can produce continuous torque levels of  232 mNm at over 7000 rpm.

The brushless motor is available in 50, 70 and 100 W versions, with 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 to configure the motor for the speed requirement of the motor 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 brushless DC motors are said to perform well, especially when comparing the torque of the motor with its diameter. They are available with tiny high-resolution encoders and compact planetary gears. maxon motor engineers are able to help with the configuration of motor, gearhead, encoder and control units to suit the specific needs of the application.
