10. Starting Method for Induction Motors
www.uotechnology.edu.iqmost inexpensive of all starting methods and is usually used for squirrel cage induction motors. It directly connects the contacts of the motor to the full supply voltage. The starting current is very large, normally 6 to 8 times the rated current. The starting torque is likely to be 0.75 to 2 times the full load torque.

Unbalanced Voltages and Electric Motors: Causes and ...
www.elongo.comsituation more severe for all the motors, both large and small. The first step in testing for unbalanced voltages is to measure line-to-line voltages at the machine terminals. Also, measure the current in each supply phase because the current unbalance is often about 6 to 10 times greater than the voltage unbalance.
