Importance of Blocked Rotor Test on Motors
What Is Blocked Rotor Test? A blocked rotor test is conducted on an induction motor. It is also known as short circuit test, locked rotor test or stalled torque test.…
Why Single phase induction motor is not self starting?
According to the double field revolving theory, we can resolve any alternating quantity into two components. Each component has a magnitude equal to half of the maximum magnitude of the…
Why High Voltage Test is important for Motors or any Electrical Equipment?
A high voltage is used to verify that the clearances and solid insulation of components have adequate dielectric strength to resist expected overvoltage conditions. It also shows that the equipment…
Construction and Working Principle of BLDC Motor
The construction and working principles of BLDC motors have many similarities to AC induction motors and brushed DC motors. Like all other motors, BLDC motors also have a rotor and…
History of Brushed , Brushless Motor and Advantages of Brushless motors
Brushed DC motors have been used since 1856, and are still often used for electrical propulsion, cranes, paper machines, and steel rolling mills. However, since their brushes wear down…
