Magnet 6 is uniformly located at the inner circumferential surface of rotor core 2, permanent magnet long 5 and short permanent magnetic
The interval setting of iron 6, easily forms dextrorotation ripple magnetic field, reduces generator loss and noise, rotor
Iron core 2 is fixed by fixed mechanism 7, and fixed mechanism 7 is located at permanent magnet and Magnetic isolation
Between layer 4, the inner periphery of rotor core 2 is provided with attachment circle 8, permanent magnet long 5 and short permanent
Magnet 6 is mounted on attachment circle 8, reduces rotor loss, improves motor efficiency, energy-conservation
Consumption reduction, it is possible to use in inflammable and explosive hazardous area, improve the peace in motor running place
Quan Xing.
Rotor surface mounted type flameproof type permanent magnet synchronous motor has a high efficiency, small volume,
The low feature of noise, with flame proof feature, widely uses and contains flammable explosive gas or dust
Hazardous area.Particularly small-power Self-starting permanent magnet motor is due to structure limitation, it is impossible to make
Make.Rotor surface mounted type flameproof type permanent magnet synchronous motor matches somebody with somebody frequency converter and controller, can
To realize motor starting and speed-regulating function, energy-saving run and Automated condtrol are easily realized.
The above embodiments merely illustrate the technical concept and features of the present invention, and this is familiar with its object is to allow
The personage of item technology will appreciate that present disclosure and implement according to this, can not be limited originally with this
The protection domain of invention.Any equivalent change or modification in accordance with the spirit of the invention, all
Should be included within the scope of the present invention.
