Abstract
The utility model discloses a motor which comprises a stator, rotators and a motor rotating shaft. The motor further comprises a circuit board which is vertical to the motor rotating shaft. An insulation board is arranged between one side of the circuit board and the stator. The outside of the other side of the circuit board is of an open-type structure. Therefore, the insulation board favorably stops heat produced by coils from transmitting to the circuit board. Meanwhile, the outside of the other side of the circuit board is of the open-type structure, and heat produced by the circuit board can dissipate by the aid of air. Accordingly, the heat dissipation effect on the circuit board is greatly improved, the motor can be used under higher temperature, application ranges of the motor are further extended, and good work performance and long service life of the motor are favorably maintained. Meanwhile, compared with the prior art, the motor has the advantages of being simple in structure, easy to process and fabricate and the like. In addition, production cost is reduced.
