Variable load application, three is positioning application.But continuous loading is mainly and is applied to certain rotating speed to rotary speed precision requirement
Field not high, such as fan, hair-dryer etc., cost is relatively low and mostly opened loop control.Variable load is mainly and is applied to rotating speed
The application changed in the range of certain is needed, has demand higher to motor speed characteristic and dynamic response time characteristic.Such as get rid of
Dry machine and compressor etc., oil pump control, electric controller, the engine control in auto industry field etc., cost is relatively higher.Greatly
Most Industry Controls and the application for automatically controlling aspect belong to positioning application, the conveying of energy are often completed, so to rotating speed
Dynamic response and torque have special requirement, the requirement to controller is also higher.When testing the speed may with photoelectricity and some
Synchronizer.Process control, Mechanical course and transport control etc. much belong to this kind of application.But, it is of the prior art straight
Flow brushless electric machine there is also some problems, for example：Power-weight ratio is relatively low.Low current high pulling torque cannot be realized.For what is generated electricity
It is inefficient.Powerful motor feels hot is excessive, and energy dissipation is more, and radiating constitutes very big problem etc..
The content of the invention
The present invention is in order to solve the above-mentioned problems in the prior art, it is proposed that a kind of stacked DC brushless motor,
Shell, two ends including being made up of front/rear cover and side shell are arranged on the rotating shaft in shell by bearing respectively, in the rotating shaft
