Abstract
The present invention is a permanent magnet synchronous submersible motor comprised of a motor stator and a rotor core. The motor stator includes a stator core formed by laminating a plurality of stator punching sheets. Each of the stator punching sheets is provided with an odd number of stator slots and any two of a X-phase coil, a Y-phase coil and a Z-phase coil are wound in each of the stator slots. The rotor core is formed by laminating a plurality of rotor punching sheets wherein each of the rotor punching sheets is provided with rotor slots and a permanent magnet inserted into each of the rotor slots. Furthermore, the permanent magnet submersible motor can be started with a conventional V/F controlled (variable frequency) converter.
