PROBLEM TO BE SOLVED: To provide a brushless windshield wiper motor capable of reducing a physical status as possible as.SOLUTION: A brushless windshield wiper motor comprises a case, a frame, and a cover. In the case, a stator 21 and a rotor 22 are provided, the rotor 22 includes a rotational axis 22a and a plurality of permanent magnets 22b. A worm wheel and an output axis, an output axial sensor 36 are provided in the frame. A control substrate is attached to the cover, and a driving device 33 is provided to the control substrate. The driving device 33 has an invertor circuit 30, a control circuit 32, a PWM signal generation circuit 34, and an induction voltage detection part 35. In the control circuit 32, a first control mode and a second control mode that control the rotation number of the rotator 22 are stored, and the driving device 33 rotates the rotor 22 in forward and backward.SELECTED DRAWING: Figure 4
