MF0255 Series

Allied Motion's Megaflux 255 series of high performance frameless brushless torque motors are computer-designed and ‑optimized to provide the highest torque density brushless torque motors available. Special attention has also been given to the minimization of cogging torque.

Frameless Megaflux motors are thin annular rings with large diameter-to-length ratios, allowing integration directly onto the driven shaft. Direct connection effectively eliminates problems of torsional resonances due to couplings and the backlash associated with gear driven systems.

Continuous stall torque for the MF0255 series ranges from 12 Nm (8.9 lb-ft) up to 116.6 Nm (86 lb-ft). No-load speed up to 1500 RPM is possible with the MF0255, depending upon winding and applied voltage.

Megalflux motors can be supplied with or without Hall effect sensors for commutation. Optimum performance is achieved with sinusoidal commutation drives, although Megaflux motors can be driven with six-step commutation drives, as well.

The Megaflux 255 series are well-suited for any precision motion application demanding high torque and compact motor size, such as semiconductor manufacturing equipment, robot bases and joints, coordinate measuring systems, stabilized gun platforms and tracking/pointing systems, and medical diagnostic and radiology equipment, to name a few.
