Brushless Motors for Gardening Equipment (BLDC Motors)

In recent years the increased capability of Li-ion battery packs has made the development of battery powered products possible. This means products that were not considered before, such as chainsaws and lawn mowers. Domel has developed two families of motors for such applications, and these motors excel in terms of minimum mass and very high efficiency. Such high performance has been achieved with the choice of the brushless DC motor. But more specifically, high quality materials were used, such as special electrical steel and high energy permanent magnets. The efficient cooling of active motor parts also helps considerably by lowering the motor mass, which is highly important in hand-held products. The two motor families differ in design and also in integration in the application; one motor is completely closed, whereas the other is an open motor with outer rotor and integrated fan.

We plan to further expand the family of motors for garden equipment and power tools, especially for battery-powered applications, where special care will be taken to further optimize efficiency, mass and cost of the motors.
