Novel motor design ensures superior power/size ratio

Measuring just 22mm in diameter, 38mm in length and weighing 0.065kg the new BGA22 rare earth, permanent magnet motor is the smallest in the Dunkermotoren range and provides an outstanding power-to-size/weight ratio, thanks to a novel axial flux stacked windings design.

The stacking of magnet and winding discs is a significant factor in the power to size ratios exceeding those of traditional coreless motors, and contributes to extended operation in battery powered systems. The motor’s axial flux design also has no cogging torque, therefore ensuring vibration-free and quiet operation.

Dunkermotoren’s modular system allows quick customisation to suit the specific requirements of individual projects, whether it requires precise positioning, low speeds with a gearbox or a combination of both.

This technology also helps to solve the problems of losing steps. For example, high-frequency noise, subsonic vibration and higher motor temperatures which can occur in stepping motors, can be avoided.
