Allied Motion's Frameless Megaflux 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 been given to the minimization of their cogging torque to enhance their performance in precision applications. 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.
