Frequency control of motor speed
WebThese speed controls are compact devices that connect to an AC motor's power supply and adjust the current to regulate the motor's speed. This provides more precise speed control and reduces energy consumption. They are used in motors where more control is needed such as conveyor belts, fans, blowers, pumps, and industrial automation. WebOct 23, 2014 · V/f’s speed control range is 1:40. Multiplying this ratio by the maximum frequency determines the VFD’s minimum running speed at which it can control the …
