Single Phase Permanent Magnet Motor |
| 摘要 |
A single phase permanent magnet motor includes a stator and a rotor rotatable relative to the stator. The stator includes a stator core and a winding wound around the stator core. The rotor includes a rotor core and a plurality of permanent magnetic poles. The stator core includes at least one first stator core lamination and at least one second stator core lamination stacked with the first stator core lamination. Inner structures of the first stator core lamination and the second stator core lamination are different. This structure reduces motor's vibration and noise, avoids possible startup dead point and improves the motor startup reliability. |
