Abstract

PURPOSE: To detect the rotational frequency of a motor through a simple construction and easily control the rotational frequency, by fitting the stator of the motor with a coil for detecting the rotational frequency of the motor.
CONSTITUTION: For example, one coil 15 for detecting the rotational frequency of the motor is provided in a casing 1 fitted with a stator magnet 3. A magnetic field generated from a rotor is detected and changed into a voltage, which is picked out from the terminals of the detection coil 15 to detect the rotational frequency. Therefore, the rotational frequency of the motor is simply detected and can be easily controlled.
