Leonard motor, Germany Leonard model, Leonard price

Leonard motor refers to a motor that can operate continuously under standard environmental conditions at 100% rated load within the 10%~100% rated speed range, with temperature rise not exceeding the motor's specified allowable value. For asynchronous motors, when the slip variation is small, the speed is proportional to the frequency; thus, changing the power supply frequency changes the asynchronous motor speed. During variable frequency speed control, it is always desired to keep the main magnetic flux constant. If the main magnetic flux is greater than the flux during normal operation, the magnetic circuit becomes oversaturated, causing an increase in excitation current and a decrease in power factor; if the main magnetic flux is less than during normal operation
