Explosion type two-speed high-temperature-resistant three-phase asynchronous motor for ships

Abstract

The invention discloses an explosion type two-speed high-temperature-resistant three-phase asynchronous motor for ships. The explosion type two-speed high-temperature-resistant three-phase asynchronous motor includes a machine base which is internally provided with a cylindrical cavity, a stator winding is assembled in the cylindrical cavity, a cast-aluminum rotor is assembled on the stator winding and is in shrinkage fit on a rotating shaft, a front end cover is mounted on the machine base at the drive end, a rear end cover is mounted on the machine base at the non-drive end, a front bearingis mounted on the front end cover, a rear bearing is mounted on the rear end cover, the front bearing and the rear bearing are open type high-temperature-resistant bearings, and high-low temperature grease is injected into the front bearing and the rear bearing. The stator winding is a double stator winding capable of meeting double rotation speed requirements, the double stator winding undergoespressure impregnation with insulating paint, and anti-mold paint is sprayed on the insulating paint. Fluororubber 246 material seal rings are disposed at the joint of the front end cover and the machine base, the joint of the rear end cover and the machine base and the position of a motor outlet wire. The explosion type two-speed high-temperature-resistant three-phase asynchronous motor has the advantages that the motor is reasonable in design and compact in structure and it is ensured that the motor runs safely and reliably in a complex environment.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a flameproof double-speed high-temperature-resistant three-phase asynchronous motor for ships. Background technique [0002] With the advancement of technology, there are more and more requirements for the function and use environment of the motor, and more and more functions are required for the same motor. In some special environments, such as when used in a flammable gas environment, it is necessary to exhaust the high-temperature gas generated when other equipment is started to avoid explosions, and there are two working conditions of high and low speeds. At present, there is no one that can do both. It meets the requirements of explosion-proof and double-speed, can also adapt to the marine environment where the ship is located, and can guarantee the normal operation of the motor after repeated impacts in high-temperature environments.

In some special environments, such as when used in a flammable gas environment, it is necessary to exhaust the high-temperature gas generated when other equipment is started to avoid explosions, and there are two working conditions of high and low speeds. At present, there is no one that can do both. A motor that meets the requirements of explosion-proof and two-speed, can also adapt to the marine environment where the ship is located, and can guarantee normal operation after repeated impacts in high-temperature environments
