Abstract

The invention discloses a wheel hub permanent magnet synchronous motor. The motor comprises a front end cover, a stator, a rotary transformer, a permanent magnet rotor and a rear end cover; the frontend cover and the rear end cover are installed at the two ends of the permanent magnet rotor respectively, one end of the stator is movably connected to the inner side of the front end cover, the other end of the stator protrudes out from a shaft hole of the rear end cover, and the rotary transformer is fixed to the end of the stator; the front end cover, the permanent magnet rotor, the rear end cover and the stator are coaxially installed. The motor has the advantages of high starting speed, good low-speed performance, high overload capacity, stable high-speed running, wide speed regulation range, wide efficient working area and the like.

Description

technical field [0001] The invention relates to a synchronous motor, in particular to a hub permanent magnet synchronous motor. Background technique [0002] There are currently two types of motors: [0003] 1. A permanent magnet motor with a rotating shaft. [0004] The traditional permanent magnet motor is wound on the stator (frame), and the permanent magnet is combined with the shaft on the rotor to form a permanent magnet rotor. After the stator winding is energized, the stator does not rotate, and the permanent magnet rotor rotates, thereby generating torque, which is output by the rotating shaft torque. [0005] 2. Outer rotor motor. [0006] The shaft of the outer rotor motor does not rotate, and the torque is output through the rotation of the outer rotor. Its structure is exactly the opposite of the traditional motor structure above, that is, the winding of the motor is on the inner stator, and the permanent magnet is on the outer rotor (on the frame). After th...
