Are you fed up with ordinary PWM circuits which do not provide perfect DC motor speed control especially at lower speeds? Then check out this outstanding single chip PWM motor speed controller circuit that will give you a complete 360 degrees of continuously varying motor speed control right from zero to maximum. POST a QUESTION or READ FAQs about how to troubleshoot electric motors such as air conditioning compressor motors, heating equipment burner or fan motors, swimming pool motors, water well pump motors. DC-motors as used in 12 VDC fans, (used in PC power supplies) have a high torque at low speed and are easier to control. Choose from a variety of industrial duty motors including 12v DC motors, 10 HP electric motors, and 1 HP electric motors. In order to keep driving without the high fan speed irritation, I removed two fuses in box under dash.
