maxon motor brushless DC motor with gear and holding brake

maxon motor Australia’s latest brushless DC motor offers small part combinations that are said to provide increased levels of power density, with the assembly offering a blend of high speed, zero motor cogging and holding power.

The servo mechanism consists of a stainless steel high-power BLDC (brushless DC), 120 W, 36 V, 22 mm motor that is capable of maximum speeds up to 25,000 rpm and a stall torque rating of over 1 Nm. It is fitted with a 22 mm ceramic planetary gearhead that further increases the torque and brings the speed down to application engineers’ required levels.

For holding overhung loads or maintaining position in power cycles, the rear of the motor has been re-engineered to accommodate a 0.1 Nm holding brake. The brake force multiplied with the gearhead ratio gives holding forces well beyond nominal gearhead ratings, according to the company.

The brake opening reaction time is ≤6 ms. This fast response allows the brake to be sequenced in dynamic positioning systems, making the combination particularly suitable for robotic rotary and linear actuators.
