Abstract
PURPOSE: To positively detect speed in a low speed range, by detecting the change of current flowing through a transistor of transistor commutators as a speed signal, and by controlling the opening and closing of a chopper transistor.
CONSTITUTION: With a motor consisting of stator windings 61, 62, 63 and a rotor 7, location detectors 181,∼183 are connected to the rotor, and transistor commutators 81∼83 to a stator. When the position of the rotor is detected by means of a hall element 19, transistors 25, 29, 33 conduct by an output signal of the detecting element, a transistor 9 of the transistor commutators conducts, and the stator is conducted. A transistor 11 simultaneously conducts at that time, current flowing through the tansistors 9, 11 varies by the dimensions of the loads of the motor 5, and a transistor 2 is in ON-OFF by a resistance 14, a condenser 15, a diode 161 and a variable resistance 17, thus controlling the speed of the motor.
