Abstract

The invention relates to a motor and in particular to a three-phase synchronous reluctance motor. The three-phase synchronous reluctance motor solves problems of low material use efficiency, loud electromagnetic noise, unsmooth output torque and high cost of a switched reluctance motor. The three-phase synchronous reluctance motor comprises a stator assembly, a rotor assembly, a hub, end covers which are fixed at the two ends of the hub and a stator shaft, wherein the end covers are supported at the end parts of the stator shaft by bearings; the stator assembly comprises a stator ring fixed on the stator shaft, 6 N stator poles fixed on the stator ring and concentrated windings wounded on each stator pole; and the rotor assembly comprises a rotor ring fixed with the hub, 7N rotor poles fixed on the rotor ring and permanent magnets fixed on the rotor poles. The motor of the invention is suitable to be used for not only driving an electro-mobile, a mine underground conveyor, a large-scale fan and the like but also a reversible mill, a flying saw, a flying shear and the like in double housing planer, milling machine and metallurgy industries.

Description

technical field [0001] The invention relates to a motor, in particular to a three-phase synchronous reluctance motor. Background technique [0002] In recent years, with the development of electronic technology, switched reluctance motors have gradually entered various production fields. The switched reluctance motor has the advantages of simple structure, low cost, high efficiency, low loss, high starting torque and low starting current. It is especially suitable for machines that require heavy-load starting and long-term low-speed and heavy-load operation, such as electric vehicles. At the same time, due to the frequent start and stop and forward and reverse conversion operation, the switched reluctance motor is also especially suitable for planer machines, milling machines, reversible rolling mills in the metallurgical industry, flying saws, flying shears, etc. However, switched reluctance motors also have many shortcomings: First, the material utilization rate of switch...
