Megaflux Series

Megaflux Series

Using over a decade's worth of brushless motor design experience, Emoteq has created the Megaflux Series of thin ring torque motors resulting in a high performance, attractively priced solution for driving large inertia or high torque load systems.
Megaflux motors have been engineered to provide very high output torques while moderating the parasitic condition of cogging torque. Cogging torque is created by the attraction of the permanent magnet rotor poles to the steel stator poles and creates a fluctuating drag torque that is undesirable in precision closed loop control systems.
The mechanical form factor of Megaflux motors, a thin annular ring with a large diameter to length ratio, allows the motor to be wrapped around a driven shaft. The direct connection of the motor to the load effectively eliminates problems of torsional resonances due to couplings and the backlash associated with gear driven systems. Direct integration also results in minimal mechanical size.
A series of through holes have been incorporated into the Megaflux stator design to provide a rugged, simple, and low cost method of mounting the stator. Using the load's bearing system, the need for separate end-caps has been removed. Similarly, the rotor features a series of holes to allow mounting directly to the load shaft.
Megaflux motors can be supplied with or without Hall effect sensors for commutation. Although the motors can be driven with six step commutation drives, for optimum performance, sinusoidal commutation is recommended.
This guide (Megaflux Catalog) is intended to show the capabilities of the Megaflux Series. However, changes can be easily made to the mechanical and electrical characteristics to suit specific application requirements. We are also structured to engineer and build completely custom motor solutions.
An enthusiastic team focused on manufacturing high quality motors, produces the Megaflux motors in Emoteq's Tulsa, Oklahoma, USA facility.
