WebAug 8, 2015 · Myth No. 4: You can run a motor at any speed with a VFD. The beauty of using VFDs is that they can vary both their output voltage and output frequency. Their ability to run the motor slower and faster than its nameplate-rated speed is part of why they are specified so often. Take the motor out of the equation, and this myth is actually true.

WebSAJ SOLAR PUMP CONTROLLER SAJ 18KW Solar Pump ControllerThe SAJ Solar Pump Controller is a variable-speed motor drive. Designed to run any IEC three-phase asynchronous motor.
