In recent years, with the wide application of machine room free and small machine room elevator, gearless transmission of permanent magnet synchronous motor has become the main trend of elevator indus

At present, the situation of energy saving, emission reduction and consumption reduction in power industry is more serious. Because frequency converter can efficiently save electric energy and improve

Servo gain is one of the simplest control methods. The output of the controller is proportional to the input error signal.The structure of the machine itself has an important influence on the servo ga

In servo system, do you know what should be paid attention to when grounding servo drive?Eight points to note for grounding of servo drives are as follows:? The correct shielding connection is at a re

Controls the starting current of the motorWhen the motor starts directly through the power frequency, it will produce 7 to 8 times the rated current of the motor. This current value will greatly incre
