Zero cogging Low friction DC motor

Australia

This special combination of DC servo motor with precious metal brushes, custom motor winding, single stage planetary gearhead and custom shaft configuration was an exclusive development for Deakin University who required an extremely linear response and low starting voltage for the demanding haptics field.

First of its kind: This was the only motor of its nature produced anywhere globally, back in 2013 when it was released. The unique requirement of high torque delivery when used as a motor combined with the need to be a highly sensitive feedback sensor, is only achievable with extremely low friction levels on the brush commutation system and the zero cogging, zero magnetic detent features of an ironless, coreless DC motor. Previously 30mm diameter was the largest motor available with this brush type.

The motor is fitted with a single stage ceramic planetary gearhead with a ratio of 6:1 to deliver the high forces required in the application however the combined efficiency of the motor and gearhead is still over 82% (90% for the gearhead and 92% for the motor).

maxon started serial production of the 40mm motors with precious metal brushes in December 2013. For more information on maxon DC motors or to find out about custom modifications to DC motors contact maxon motor Australia in our Sydney office on +61 2 9457 7477.
