Induction Motor Slow Start at Arthur Yasmin blog

Induction Motor Slow Start. However, what you are attempting to do is change the speed by varying the voltage. No power — if the motor fails to start and there is no rotation, electrical humming noise, or signs of heating, tripped overload relays are the most likely issue. A soft starter utilizes voltage reduction during motor startup, gradually increasing the voltage. This is an acceptable method in some applications and with some types of induction motors. In other words, a soft starter is an electric device that reduces the motor starting. It also protects the motor against mechanical tears due to a full voltage supply. That time to start up seems fairly normal for a bench grinder. This helps the motor accelerate slowly and smoothly pick up speed. But the behavior of the lamp seems to indicate a lot of voltage drop, which could be a weak supply, or excessive current draw. Sometimes you can get it to run well, but most of the time it either does not move at all, or runs very slowly and makes that horrible growling noise of a stalled ac motor. Check the winding with a series test lamp or megger and correct it. The most common cause of a motor not starting at reduced voltage is due to poor communication among user, motor manufacturer, and process.
