Description

technical field [0001] The invention relates to the technical field of motors, in particular to a low-speed and high-torque permanent magnet motor for ships. Background technique [0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an electrified coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electric rotational torque. The permanent magnet motor provides excitation with permanent magnets, which makes the motor structure simpler, reduces the processing and assembly costs, and saves the slip rings and brushes that are prone to problems, especially for some low-speed and high-torque permanent magnet motors. Some large-scale processing equipment has been widely used. [0003] However, in the actual use of the traditional low-speed high-torque permanent magnet motor, the temperature inside the motor will continue to rise after a long time of operation, and the traditional heat dissipation is ...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual use of traditional low-speed high-torque permanent magnet motors, after a long period of operation, the temperature inside the motor will continue to rise, and traditional heat dissipation is mostly carried out spontaneously through the rectangular heat dissipation strips provided outside the motor. , resulting in low heat conduction efficiency and affecting the heat dissipation effect; in addition, when the motor is not in use, after a long period of standing on the surface, it is easy to accumulate dust. When the dust accumulates a lot, it will affect the heat dissipation and normal operation of the motor. ;In addition, during the installation process of the motor, since most of the mounting seats of the traditional motor are fixed, it is difficult to adapt to the installation requirements under different conditions
