The electric motor includes a coil array having a plurality of magnetic coils; a magnet array having a plurality of permanent magnets; a magnetic sensor outputting an output signal that changes in analog fashion depending on relative location of the magnet array and the coil array; a drive control circuit; and an output waveform correcting unit. The output waveform correcting unit corrects the waveform of the output signal of the magnetic sensor based on the voltage level of the output signal of the magnetic sensor, in such a way that the output signal of the magnetic sensor is shaped to prescribed waveform shape during operation of the electric motor.
