A motor includes a housing (1), a front cover (6), a rotating shaft (8), and a cooling fan (7). The front cover (6) is formed with multiple air guiding fins (63) and multiple inlet holes (64). The housing (1) defines at least one communication hole (13) at its surrounding wall. In use, a central portion of the air current generated by the cooling fan (7) can be guided by the air guiding fins (63) to pass through the inlet holes (64) to enter the motor's housing (1). An outer portion of the air current can flow along the outer surface of the housing (1). The way of dissipating heat through multiple paths allows the heat generated in the motor to be dissipated more effectively, so that heat is not easy to accumulate in the motor, and thus the performance and service life of the motor can be increased. |
