The present invention provides a motor. The motor is provided with a movable body and an electromagnetic coil, wherein the movable body being arranged a plurality of permanent magnetic with alternate magnetic polar, a plurality of electromagnetic coils are configured as stators and movable bodies without contact, and exciting current is directly supplied for the electromagnetic coils as drive waveform, such that the movable body may move. The motor is characterized in that the motor is controlled by the follow components: a sensor, which outputs level corresponds a detection signals changing along the periodicity magnetic field change caused by the movement of the permanent magnetic; a frequency-voltage converting portion, outputting a corresponding voltage for the detection signal; a level adjust circuit, outputting magnetic hysteresis level signal corresponding to the output level of the frequency-voltage converting portion; a window comparator, outputting a pulse series shape drivesignal with given duty ratio based on the detection signal of the sensor and the level comparative result of the magnetic hysteresis level signal; and a drive circuit, supplying exciting current for the coil body based on the drive signal.
