Title:
SUBMERSIBLE PERMANENT MAGNET SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2015/096547
Kind Code:
A1
Abstract:
A submersible permanent magnet synchronous motor (1000) includes a motor casing, a stator and a rotor are correspondingly arranged in the motor casing, and two ends of the motor casing are respectively sealed and are connected to other external devices through connecting devices, such that an integrated-structure casing assembly (100) can be formed; the stator and the rotor are a stator assembly (200) and a rotor assembly (300) with multi-section type structures, respectively, the stator assembly (200) is fixed on the casing assembly (100), and the rotor assembly (300) is penetrated and arranged in the stator assembly (200); oil is injected into the casing assembly (100). By adopting the integrated-structure motor casing assembly, the stator assembly (200) and the rotor assembly (300) with multi-section type structures, the operation reliability and the performance of the motor are improved.
