Description
Technical field
The present invention relates to a kind of permagnetic synchronous motor, particularly a kind of high-quality multipurpose synchronous machine.
Background technology
As everyone knows, the permagnetic synchronous motor volume is little, energy-conservation, be a kind of flourish motor product, but there is the pressure regulation difficulty in magneto alternator, scarce limit such as waveform difference; Problems such as permanent magnet synchronous motor starts difficulty, and staring torque is little; The big deficiency that waits of mag-dynamo direct current ripple; To make high-quality permagnetic synchronous motor in a word many difficult problems extremely to be solved are arranged.
Summary of the invention
The object of the present invention is to provide a kind of high-quality multi-use permanent magnet synchronous motor.Be used as the generator time spent, good voltage waveform, voltage can be regulated, pressure regulation precision height; When being used as DC generator, as long as additional rectification link is made the little high-quality DC generator of direct current ripple easily; Be used as the synchronous motor time spent, startup is easy, moment is big, operates steadily, and need not add controlling unit in the rotor, and is simple in structure, easy to manufacture.This motor volume is little, in light weight, energy-conservation, reliability is high.
Technical scheme of the present invention is: a kind of permagnetic synchronous motor, this device is formed by main motor and the coaxial assembling of stand-by motor, the rotor of main motor by the punching of band yoke, not pressing by steel riveting bar with the punching of yoke forms, be assembled on the main shaft, the damping cage of being made up of copper conductor on it is not mounted with permanent magnet, non-magnetic guiding loop in the punching with yoke on main shaft.In the jet-bedding of rotor core, be embedded with excitation winding and carry out excitation.
The invention has the advantages that: magnetic, the existing magneto of electric composite excitation can reduce volume, energy-conservation, reliable characteristics again, can reduce the power of direct current excitation again.Improve electric efficiency; Overcome the difficult problem of magneto adjustable magnetic, this adjustable magnetic method had been not only simple and reliable, but also realize easily; Because rotor is made by the soft iron punching, control when magnetic pole parameter shape can design improves many, the realization easily of measure of voltage waveform, has guaranteed that voltage waveform is high-quality; When being used as synchronous motor, need not be on rotor the installation and control device, staring torque is big, it is reliable to operate steadily, and makes that brushless synchronous motor product are of fine quality, the manufacturing cost reduction, is a kind of synchronous motor of novel, this synchronous motor is a non-brushing, also easy frequency-adjustable speed-adjustable; Belong to dynamical energy-conserving product, realize a tractor serves several purposes, accommodation is wide, saves purchase commodity, uses economy, and good economic benefit and social benefit will be arranged.
