Brushless DC motor with axial flux design

By Frank Tobe | February 3, 2016

DunkermotorenDunkermotoren breaks the mold with its brushless DC motor development. The result is a motor concept which is characterized by a high power density and robustness. To meet the market demand with an attractive cost-benefit ratio, Dunkermotoren has developed a new axial flux motor design with stacked windings.

The new BGA 22×22 is an ironless DC motor. The ironless design concept offers the advantage of zero cogging torque resulting in vibration-free operation inherent in iron-core designs. The motor utilizes rare-earth permanent magnets and is electronically commutated (brushless).

The winding technology employed coupled with the rotor stack construction provide the basis for an impressive volume-performance which exceeds that of classic non-ferrous motors. The BGA 22×22’s high efficiency also lends itself well to battery-powered applications. The motor’s broad speed range is suitable for combinations with gear boxes as well with the current design capable of speeds up to 16,000 rpm.

The motor is equipped with three Hall sensors providing feedback for commutation. They can also be used for speed control and positioning feedback. It is also possible to combine the BGA 22×22 with an encoder for applications requiring higher resolution than Hall the sensors can provide. Hall power supply, Hall outputs, and phase connections to the motor are made via a low-profile, flat ribbon cable.
