Energy-saving switch reluctance machine with modularized salient poles of stator and rotor

Abstract

The invention discloses an energy-saving switch reluctance machine with modularized salient poles of a stator and a rotor. The stator of the energy-saving switch reluctance machine is formed by U-shaped iron core modules which are fixed on the inner circumference wall of a shell at equal intervals, and a pair of stator coils around the U-shaped iron core modules; the rotor of the energy-saving switch reluctance machine is formed by a rotor shaft, a cylindrical rotor salient pole carrier fixedly connected with the rotor shaft, and rotor salient pole modules evenly arranged on the outer circumference wall of the cylindrical rotor salient pole carrier; and the rotor shaft is arranged on a left end cover and a right end cover of the shell by bearings. The energy-saving switch reluctance machine has the advantages that as the salient poles of the stator and the rotor are both modularized, the energy-saving switch reluctance machine greatly saves silicon steel sheets compared with the whole structure of an existing switch reluctance machine; (2) the two stator coils are arranged on the stator salient pole of the energy-saving switch reluctance machine instead of one stator coil on a stator salient pole of the existing switch reluctance machine, so that the thicknesses of each stator coil can be reduced, and a copper wire is saved; and the length of a magnetic path is reduced, so that the loss of the magnetic path is reduced, and the energy-saving effect is improved.

Description

technical field [0001] The invention relates to an energy-saving switched reluctance motor in which both the salient poles of the stator and the rotor are modularized. Background technique [0002] Switched reluctance motor is a new type of speed regulating motor. The speed regulating system has the advantages of both DC and AC speed regulating systems. It is the latest generation of stepless speed regulating system following frequency conversion speed regulating system and brushless DC motor speed regulating system. . It has simple and firm structure, wide speed regulation range, excellent speed regulation performance, high efficiency in the whole speed regulation range, and high system reliability. It is mainly composed of four parts: switched reluctance motor, power converter, controller and position detector. The controller includes a control circuit and a power converter, and a rotor position detector is installed at one end of the motor. The motor part is called a r...

AI Technical Summary

Problems solved by technology

[0005] (1) Since both the stator and the rotor core are integral structures, there is a great waste of silicon steel sheets;

[0006] (2) The stator coil is thicker, which not only wastes copper wire, but also has poor heat dissipation effect;

[0007] (3) Since both the stator and the rotor core are integral structures, the closed magnetic field line loop is too long and the magnetic circuit loss is large;

[0008] (4) Since both the stator and the rotor core are integral structures, for motors with different capacities and numbers of salient poles, more molds and stamping equipment are required, resulting in an increase in cost and waste of stamping equipment and molds
