The Role Of Motor Overload Protection

The Role Of Motor Overload Protection

During operation, short-time overload is generally allowed (the output power exceeding the rated value is called overload). However, if the load time is too long and the temperature rise of the motor exceeds the allowable value, it will cause insulation aging, shorten the service life, and even burn the windings in severe cases. . Therefore, …

How To Measure The Starting Current Of A Motor?

How To Measure The Starting Current Of A Motor?

The starting current refers to the inrush current of the electrical equipment (inductive load) when it is just started. It is the amount of current change from the moment when the motor or inductive load is energized to the short time when the operation is stable. This current is generally 4-7 times the rated current. …
