Abstract

The invention relates to the technical field of motors, and discloses a rotor ironless permanent magnet synchronous motor, which comprises a motor outer shell, wherein a front end cover is fixedly mounted on the left side of the motor outer shell, a rear end cover is fixedly mounted on the right side of the motor outer shell, the left side of the front end cover and the right side of the rear endcover are each fixedly provided with a bearing outer cover, the left side of the front end cover and the left side of the rear end cover are each fixedly provided with a bearing inner cover, bearingsare fixedly mounted in the interior of the front end cover and the interior of the rear end cover, oil inlet pipes are fixedly mounted in the interior of the two bearing outer covers, a wind cover isfixedly mounted on the right side of the rear end cover, a stator is are fixedly mounted on the inner surface of the motor outer shell, and the inner surface of the stator is movably connected with arotor. The rotor ironless permanent magnet synchronous motor adopts a polymer material to replace silicon steel sheets and other ferrous magnetic conductive materials, realizes ironless permanent magnetization, has no iron loss and high magnet usage rate, and reduces the magnet usage amount.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotor ironless permanent magnet synchronous motor. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy. It uses a energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force. The motor is divided into DC motors and AC motors according to the power supply used. The motors in the power system are large Part of it is an AC motor, which can be a synchronous motor or an asynchronous motor. The motor is mainly composed of a stator and a rotor. The direction of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line. The working principle of the motor is that the magnetic field affects the current. The action of force makes the motor rotate. [0003] At present, in order to save energy and reduce emissions, a...
