State embedding between the inwall of DC brushless motor and described drive circuit board and described housing to have there is insulation, anti-
Water and the casting glue of heat conductivility.
As further improvement of the utility model, described housing is the columnar structured of stainless steel, institute
State a length of 65.7mm of housing, a diameter of 20mm.
As further improvement of the utility model, described DC brushless motor is located at the side in described housing,
Described drive circuit board is located at the opposite side in described housing.
As further improvement of the utility model, described drive circuit board includes the digital signal being sequentially connected with
Process chip, signal conversion chip and signal amplification chip,
Described digital signal processing chip is connected with outside host computer, and described digital signal processing chip is by institute
State the manipulation instruction that host computer sends and be converted to numerical control instruction, and described numerical control instruction is delivered to
Described signal conversion chip；
Described numerical control instruction of stating is converted to motor driving instruction by described signal conversion chip, and by described
Motor driving instruction is delivered to described signal amplification chip；
Described signal amplification chip is connected with described DC brushless motor, and described signal amplification chip is by described electricity
Machine driving instruction carries out power amplification, and the described motor driving instruction after power amplification is delivered to institute
State DC brushless motor, to realize the driving to described DC brushless motor.
Compared with prior art, all of Signal Processing Element is all integrated to one piece and drives electricity by this utility model
On the plate of road, then drive circuit board and DC brushless motor Ontology integration are encapsulated to a housing, this reality
Not only achieve the integrated of motor driver and miniaturization with novel, and its performance more stably may be used
Lean on.
