Embodiment Construction

[0010] A permanent magnet synchronous motor includes two parts, a main motor and an auxiliary motor. The auxiliary motor is an AC exciter, and the rotor structure of the main motor is formed by punching sheet 4 with a yoke and punching sheet 7 without a yoke through steel riveting strips 9 and assembled on the main shaft 1 . Punching sheet 4,7 is punched by soft iron plate, has the damping cage that copper conductor 8,10 forms on it. A permanent magnet 5 and a non-magnetic permeable ring 6 are arranged in the punching sheet without a yoke on the main shaft 1 . In the punching slot of the rotor core, the excitation winding 2 is embedded for excitation. The armature winding of the main motor is a single-phase or three-phase general-purpose winding designed according to the sinusoidal winding. Permanent magnet synchronous motor has the characteristics of small size, light weight, easy excitation, good voltage waveform, easy frequency regulation, speed regulation, excellent stea...

Abstract

A permanent-magnetism sychronous motor features that the rotator of the main motor is structured by two parts such as a permanent magnet being set up on one part and a DC excitation winding set up onanother part, its punched sheet being formed by punching with soft iron plate and being equipped with damping cage built by copper conductor; the stator armature of the main motor is designed into a per sine winding with harmonic winding. An auxiliary motor is a AC exciter. The motor is brushless and can be used either as a synchronous generator or as a motor.

Description

technical field [0001] The invention relates to a permanent magnet synchronous motor, in particular to a high-quality multipurpose synchronous motor. Background technique [0002] As we all know, permanent magnet synchronous motors are small in size and energy-saving, and are a booming motor product, but permanent magnet synchronous generators have problems such as difficult voltage regulation and poor waveform; permanent magnet synchronous motors have problems such as difficulty in starting and small starting torque; The permanent magnet DC generator has large DC ripples and other shortcomings; in short, there are many difficult problems to be solved to make a high-quality permanent magnet synchronous motor. Contents of the invention [0003] The purpose of the present invention is to provide a high-quality multipurpose permanent magnet synchronous motor. When used as a generator, the voltage waveform is good, the voltage can be adjusted, and the voltage regulation accur...
