  • Drive unit for a hair cutting machine
    Patent number: 8610329
    Abstract: A drive unit for a hair cutting machine comprises a driving motor that includes a substantially U-shaped stator which has a first leg, a second leg, and at least one additional leg located between the first leg and the second leg, at least one field coil which can be disposed on the at least one additional leg, and an armature. Lateral air gap sections are formed between the first and second leg and the armature while central air gap sections are formed between the additional leg and the armature. The central air gap sections and the lateral air gap sections extend at an angle from a longitudinal axis. A first nose, which faces away from the additional leg, is arranged at the end of the first leg, while a notch, which faces the additional leg and corresponds to the first nose, is arranged on the second leg.
