Problems solved by technology

However, the insulation cannot be ensured between the silicon steel sheets 21a, and the eddy current will form a path passing through the adjacent silicon steel sheets
At this time, the silicon steel sheet 21a becomes a resistance to the current, so the longer the path of the eddy current, the greater the resistance, which eventually becomes iron loss, which together with the meter current load loss reduces the efficiency of the induction motor

Abstract

This invention discloses a manufacturing method for an induction motor, its rotor and stator. The induction motor includes a stator iron core, coils rotator and a rotor conductor. Radiation multistator slots arrayed in a certain interval are formed on silicon sheet and aligned along the axial way to accumulate to a stator iron core, coils are winded on the stats applied by a AC power supply to forma rotating magnetic field, the rotor core and the stator iron core constitute concentric circles, insulation films are formed on the rotor slots to prevent current leakage from the slots and the rotor conductor is designed on the rotor slots and the induced current through coils generates a torque.

Description

technical field [0001] The invention relates to an induction motor, in particular to a manufacturing method of the induction motor and the rotor and the stator of the induction motor. Background technique [0002] Generally speaking, a motor is a machine that converts electrical energy into mechanical energy to obtain rotational power. It is roughly divided into DC motors and AC motors, and induction motors are a type of AC motors. An induction motor is one of typical AC motors. Through the change of the electromagnetic field of the primary coil connected to the power supply, the secondary coil generates current, and the current generated by the secondary coil interacts with the rotating magnetic field to generate rotational torque. [0003] The following is a brief description of the structure of the induction motor with reference to the accompanying drawings: figure 1 It is a structural sectional view of a general induction motor. As shown in the figure, the induction m...
