Problems solved by technology

The loss of the motor is mainly composed of five parts: iron core loss, stator resistance loss, rotor resistance loss, mechanical loss, and stray loss. 25% of the loss, however, the fan structure used in the current motors in our country is difficult to help improve the efficiency of the motor

Abstract

The invention belongs to the technical field of electric motors, and relates to a fan for a three-phase asynchronous motor, which includes a fan body, a shaft sleeve is fixed in the center of the fan body, and a conical bucket is arranged on the peripheral surface of the shaft sleeve. A number of fan blades are arranged, and the two ends of the root of each fan blade are fixedly arranged on the outer end of the cone barrel and the front end of the outer peripheral surface of the shaft sleeve, and the front part of the top of the fan blade is provided with a first chamfer, and the rear part of the top is A second chamfer is provided, and two ventilation holes are symmetrically opened on the fan body along both sides of the shaft sleeve. The fan has a reasonable and ingenious structure, can greatly reduce the wind resistance loss and the mechanical noise of the motor, and at the same time greatly improve the efficiency of the motor.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a fan for a three-phase asynchronous motor. Background technique [0002] Starting from saving energy and protecting the environment, high-efficiency motors are the current international development trend. The United States, Canada, and Europe have successively promulgated relevant laws and regulations. With my country's accession to the WTO, the huge competitive pressure and challenges of the international community that my country's motor industry is facing are increasing day by day. From the perspective of international and domestic development trends, it is very necessary to promote China's high-efficiency motors. This is also a requirement for product development, so that my country's motor products can keep up with the international development trend, and it is also conducive to promoting industrial technological progress and product export needs. . According to statistics, i...
