Description
Technical field
The utility model relates to a kind of rotor surface mounted type flameproof type permanent magnet synchronous motor, belongs to motor technology field.
Background technology
Rotor surface mounted type flameproof type permanent magnet synchronous motor is used in the hazardous area that oil, chemical industry, colliery and space flight etc. contain flammable explosive gas or dust, for low-power equipments such as Driving Fan, water pump, compressor, conveyers.Flame-proof type rotor surface mounted type permanent magnet synchronous motor has explosion-proof casing, can ensure the fail safe in hazardous area.Flame-proof type rotor surface mounted type permanent magnet synchronous motor has that volume is little, efficiency is high, invariablenes turning speed, speed governing facilitates the features such as accurate, is the renewal product of former Flame-Proof Three-Phase Induction Motors.Rotor surface mounted type flameproof type permanent magnet synchronous motor rotor loss of the prior art is high, and motor efficiency is low, does not meet necessary requirement.
Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of rotor surface mounted type flameproof type permanent magnet synchronous motor.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of rotor surface mounted type flameproof type permanent magnet synchronous motor, comprise rotating shaft, rotor core, squirrel-cage bar and permanent magnet, rotor core center is located in rotating shaft, Magnetic isolation layer is provided with between rotating shaft and rotor core, rotor core excircle is provided with squirrel-cage bar, rotor core inner circumferential surface mounted type has permanent magnet, and permanent magnet comprises long permanent magnet and short permanent magnet, and rotor core inner circumferential surface is evenly located at by long permanent magnet and short permanent magnet.
The related content of technique scheme is explained as follows:
In technique scheme, long permanent magnet and short permanent magnet interval are arranged.
Further technical scheme, rotor core is fixed by fixed mechanism, and fixed mechanism is all located between permanent magnet and Magnetic isolation layer.
Preferably, rotor core inner periphery is provided with attachment circle, and long permanent magnet and short permanent magnet are mounted on attachment circle.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Reduce rotor loss, improve motor efficiency, energy-saving and cost-reducing, inflammable and explosive hazardous area can be used in, improve the fail safe in motor running place.
