Abstract

The utility model relates to a compact oil-cooled permanent magnet synchronous electric roller, which relates to the field of transmission machinery and comprises a roller body, a permanent magnet synchronous motor, a left end cover component, a right end cover component and a planetary reducer. The permanent magnet synchronous motor comprises a stator, a front end cover assembly, a motor rear end cover and a rotor assembly. The left end cover assembly and the right end cover assembly are both in interference fit with the roller body; after lubricating oil is injected into the roller body, the roller body rotates during working, and the lubricating oil can be poured on a motor stator during rotation. The compact permanent magnet synchronous motor is redesigned and is different from a traditional motor, the motor comprises a motor shell and a motor stator which are directly exposed, and a front sealing end cover and a rear sealing end cover are arranged on the two sides of the motor shell, and after lubricating oil is injected into the roller body, the lubricating oil is poured on the motor stator when the roller body rotates. Compared with a traditional case, the temperature of the permanent magnet synchronous motor is reduced more directly and effectively.
