Abstract

The invention discloses an ultra-high-efficiency low-voltage three-phase asynchronous motor, which comprises a cast iron base, a wire winding stator, a finished rotor, a front end cover assembly, a rear end cover assembly, a front bearing assembly, a rear bearing assembly, an outer fan and an outer fan cover, wherein the cast iron base is used for installing the wire winding stator, the finished rotor is arranged in the wire winding stator, the end cover assemblies and the bearing assemblies are used for supporting the finished rotor, the outer fan is arranged on a shaft and located in the outer fan cover at the tail of the shaft. According to the invention, based on the new cast iron base, the outer diameter of the existing motor stator punching sheet is increased, so that the radial height of the stator groove profile is increased under the condition that the magnetic flux density of the stator iron core yoke is not increased so as to increase the area of the stator groove profile, improve the motor line load capacity and reduce the copper loss; the iron loss of the motor is further reduced by using the low-loss silicon steel sheet; and the energy efficiency grade reaches or exceeds IE4 energy efficiency grade standard by reducing copper loss and iron loss.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an ultra-super-high-efficiency low-voltage three-phase asynchronous motor. Background technique [0002] Three-phase asynchronous motor is a kind of induction motor. It is a type of motor powered by simultaneous access to 380V three-phase AC power supply (phase difference 120 degrees). Since the rotor and stator of the three-phase asynchronous motor rotate in the same direction and different The rotational speed becomes rotation, and there is a slip, so it is called a three-phase asynchronous motor. Three-phase asynchronous motor is a kind of induction motor. After the stator is fed with current, part of the magnetic flux passes through the short-circuit ring and induces current in it. The current in the short-circuit ring hinders the change of the magnetic flux, resulting in a phase difference between the magnetic flux generated by the part with the short-circuit ri...
