Brushless DC motor

The EC-powermax 22 achieves high torque at slow speeds compared to other similar-sized brushless DC motors. The EC motor is particularly suitable for process applications like handheld tools such as slicing and drilling machines where top performance is required per volume and weight unit. It complements the 30 mm option with a 22 mm diameter motor and performance of up to 120 W and, like the EC-powermax 30, is available in two lengths.

The existing rotor comprising two pole pairs is fitted with the best magnetic material currently available on the market. For electronic commutation, the magnetic field is sensed through Hall sensors and the rotor position detected. All the benefits of brushless DC motors with air-flux (‘ironless’) winding also apply to the 4-pole version. Like its big brother, the EC-powermax 30, the EC powermax 22 has no detent because of the grooveless stator, resulting in good control characteristics which are particularly beneficial for positioning operations.

The EC-powermax 22 is available in two lengths, with an operating range of 90 to 120 W depending on the version. maxon’s modular system means that it can be combined with 32 mm planetary gearheads. maxon motor also offers the corresponding electronics for operating or controlling the motor.
