MATTEI motor Germany MATTEI model MATTEI price

MATTEI motor refers to a motor that, under standard environmental conditions, operates continuously with 100% rated load within the 10%~100% rated speed range, without the temperature rise exceeding the motor's specified permissible 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 speed of the asynchronous motor. 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
