Problems solved by technology

However, the current AC asynchronous motors have the following problems: 1. The magnetic flux density is not high, and the efficiency of the motor is low; 2. The eddy current of the motor is large, and the loss is serious; 3. The rotor is solid and the load is heavy; 4. The grooves on the stator and rotor The slot is wider, the width of the iron teeth is small, and the electromagnetic conversion efficiency is low; 5. The amount of winding copper wire is large and the cost is high

Abstract

The invention discloses a hollow energy saving motor. The hollow energy saving motor comprises a stator and a rotor, wherein the stator comprises a stator core and a stator winding, wherein a plurality of grooves are uniformly distributed on the inner circle of the stator core, and the stator winding is arranged on stator grooves; the rotor comprises a rotor core and a rotor winding, wherein a plurality of grooves are uniformly distributed on the outer circle of the rotor core, and the rotor winding is arranged on rotor grooves; the area of each phase tooth of stator iron teeth on the inner circle of the stator core doubles the area of each phase tooth of stator iron teeth of conventional three-phase asynchronous motors. The hollow energy saving motor can increase the magnetic flux density of the motor, improve the motor efficiency, reduce the consumption of winding copper wires and reduce the cost.

Description

technical field [0001] The invention relates to a hollow energy-saving motor, which includes a stator and a rotor. The stator includes a stator core with a plurality of grooves evenly distributed on the inner circle and a stator winding arranged on the stator grooves. The rotor includes a plurality of grooves evenly distributed on the outer circle. The rotor core and the rotor winding arranged on the rotor groove. Background technique [0002] An electric motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, a current passes through the armature squirrel-cage aluminum frame and is subjected to the action of the magnetic field to make it rotate. Usually, the active part of the motor makes a rotary motion, which is called a rotor mo...
