SWITCHLESS DIRECT CURRENT MOTOR

The motor is used to drive external storage devices in computer engineering, audio and video appliances, etc. It helps to improve the precision and dynamic stability in maintaining the operating speed, and reduces the time needed to set the working mode. The motor consists of a magnetic rotor (1), mechanically coupled to a tacho-winding (2), which is connected to an amplifier-former (3), a rotor position sensor (4), connected to the inputs of a distribution unit (5), three phase coils (7, 8 and 9), with control inputs connected to the activating outputs of the distribution unit (5). The motor also incorporates the respectively connected reference voltage source (10), adjusting amplifier (11), quartz oscillator (12), programmable frequency divider (13 and 18), a double splitter (14), a delay unit (15), AND circuits (16, 17, 20, 21 and 22), an EXCLUSIVE OR circuit (19), a triple state buffer (23) and controllable dephasers (24, 25 and 26).
