The motor rotor is a whole plastic encapsulated direct current brushless motor rotor which is made of a rotor strengthening plate, a permanent magnetic steel plate, a rotor connecting interface steel plate and rotor insulation plastics through the injection molding. The motor stator is a plastic encapsulated direct current brushless motor stator which is made of stator insulation plastics, silicon steel sheet and winding wires through the injection molding. A Hall element feedback component is fixed on the motor stator. Insulation plastics are adopted for the once injection molding of the direct current brushless motor rotor and stator. The upper and the lower end covers of the motor are reduced, and the direct current brushless motor rotor and stator can be respectively encapsulated wholly. And an interface which is provided with high precision and is connected with the external is injected to guarantee the connection precision with an external interface. With the technology adopted, the manufacturing and material cost is lowered, and the precision and the safety of products are improved.
