Problems solved by technology

[0003] In summer, the temperature is high, and the bearings of asynchronous AC motors are often damaged due to excessive temperature. The general solution is to use an additional fan or compressed air for forced heat dissipation. This is not only a cumbersome process, but also increases the cost

Abstract

The invention provides an asynchronous alternating current motor which comprises a motor body. A fan cover is arranged on the tail end of the motor body. A fan is arranged in the fan cover. A gap is arranged between the fan cover and the motor body. A front bearing is arranged on the other end of the motor body. The motor body is sleeved by a guide vane. One end of the guide vane is arranged on the upper side of the fan cover, and a gap is arranged between the guide vane and the fan cover. The other end of the fan cover is arranged on the upper side of the front bearing. The motor body is provided with a fan cover fixing hole and a guide vane fixing hole. One end, which is located on the fan, of the guide vane is fixed with a nut through a fan fixing hole. One end, which is located on the front bearing, of the guide vane is fixed with a nut through a guide vane fixing hole. The asynchronous alternating current motor has the advantages of simple structure and reasonable design. Wind in the fan is drained to the front bearing by sleeving the motor body through the guide vane, which solves the problem of poor heat dissipation of the front bearing.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to an asynchronous AC motor. Background technique [0002] An asynchronous AC motor is an electric drive device that converts electrical energy into mechanical energy. It mainly consists of a stator, a rotor and an air gap between them. After the stator winding is connected to the three-phase AC power supply, a rotating magnetic field is generated and the rotor is cut to obtain torque. Three-phase AC asynchronous motors have the advantages of simple structure, reliable operation, low price, strong overload capacity, and convenient use, installation, and maintenance, and are widely used in various fields. [0003] In summer, the temperature is high, and the bearings of asynchronous AC motors are often damaged due to excessive temperature. The general solution is to use an additional fan or compressed air for forced heat dissipation. This is not only a cumbersome process, but also inc...
