Consumption eliminates multi-stage speed-reducing consumption；Spark is not generated, is particularly suitable for explosivity place, there is explosion-proof；
（1）Heat emission hole is designed as extending out interior narrow shape, keeps the heat dissipation effect of entire motor better, and positioned inside has filtering
Layer, not only can be dust-proof, but also can be with noise control；
（2）The use of thermocirculator allows the inside thermal current of motor to be able to be recycled rapidly, prevents long time running
The problems such as working and causing short circuit；
（3）The use of two-way spindle can drive multiple machine runs simultaneously；And radiator fan is disposed among two rotors,
Circulating current is easily formed to radiate.
