High power density brushed dc motors

14 November 2015

Portescap’s new Athlonix 22DCP high-power, 22mm brushed dc mini-motors with Alnico magnets are now available in the UK from Mclennan. They are available with a choice of graphite or precious metal commutation.

The 22DCP’s coreless design with its optimised self-supporting coil and magnetic circuit is available in eleven winding options from 3 through 48Vdc. The motor delivers a maximum continuous torque of up to 6.5mNm - with a higher measured stall torque than similar 22mm diameter motors. Speeds up to 10,000rpm are possible, with precise and repeatable torque/speed characteristics for maximum control.

With a nominal motor length of 32mm, the 22DCP is available with single or dual shafts, while users can select single or dual bearings. The constant force spring design for the carbon brush commutation version extends its working life, while Portescap’s proven ‘REE’ feature, that reduces winding electro-erosion, prolongs the lifespan for both commutation versions.

The new motor is available for use with Portescap’s wide range of miniature planetary and spur gearheads in addition to encoders such as the new M Sense B where accurate positioning and closed loop motion feedback is required. User-customised versions with special mechanical or electrical features are also available.
