Universal motor and lamination for stator thereof |
摘要 |
A lamination 10 for the stator of a universal motor has two poles 12 and a flux return path in the form of a ring 14 joining the two poles together. Each pole 12 has a pole face 16 defining there between a rotor space 20 for accommodating a rotor and each pole 12 has a neck portion 18 for receiving stator field windings. The width A of the ring 14, the length B of the pole 12, the radial distance C between the pole faces 16 and the width D of the neck portion 18 are selected according to formulae to achieve improved power output and output torque.
