Problems solved by technology

[0010] The distortion of the magnetic line density at the air gap mentioned above seriously affects the characteristics of the motor
like image 3 As shown, due to the distortion of the magnetic force line density at the air gap, when the motor starts, the torque contains multiple high-order harmonic components (such as the 3rd harmonic, 5th harmonic and 7th harmonic, etc.), resulting in Some unnecessary torque, which reduces the starting characteristics of the motor

Abstract

This invention discloses a rotor of a synchronous reluctance machine including a core, several conducting rods inserted into the outer cycle of the core in uniform space and several blocking plates plugging into the core divided into two symmetrical groups around the shaft-center. The said conducting rods includes: the conducting rods inserting into the outer cycle of the core and connecting with the ends of the blocking plates and deep-inserting rods inserting but not connecting with their ends, the outer surfaces of the rods are just aligned with the peripheral face of the core and the deep-inserting rods deep in the peripheral face of the core forming a certain distance between the two outer surfaces.

Description

technical field [0001] The invention relates to a synchronous reluctance motor, in particular to a rotor of a synchronous reluctance motor Background technique [0002] Synchronous motor is a kind of AC motor. Generally speaking, when the frequency of AC power supply is constant, the speed of synchronous AC motor has nothing to do with the load. That is to say, synchronous AC motor is a uniform speed motor with synchronous speed as the speed. For the synchronous reluctance motor, its torque is generated by the reluctance component. In other words, the rotor of the synchronous reluctance motor rotates by the reluctance torque. [0003] The existing ordinary synchronous reluctance motor generally includes: a stator and a rotor; a coil is arranged on the stator, and the rotor is arranged in a cavity surrounded by the stator; after the stator coil is connected to an alternating current, a rotating magnetic field is formed around the stator, and the rotating magnetic field Under...
