One contactor burnt for high velocity and a replced contactor won't engange, initially the coils re fed using a nutural as well as the one particular i changed is just dealing with a phase. be sure to assistance the way to go concerning this
The overcurrent condition might cause damage to the motor, electric power traces and generally is a hazard for operators. Such an amount of recent is just too risky for a quick instant.
A three-phase motor is created to operate on the three-phase AC electric power provide. In a very three-phase process, three sinusoidal voltages are applied to the motor windings, Every single phase being offset by a hundred and twenty levels from the others.
The induction motor is generally Utilized in industrial apps. The squirrel cage induction motors are Utilized in household in addition to industrial purposes In particular in which the pace Charge of motors will not be desired such as:

Three-phase induction motors can also be built-in into a motor starter program for far better Command and defense.
The shape of the rotor is resembling The form with the cage of a squirrel. For that reason, this motor is recognized as a squirrel cage induction motor.
This can be useful for motors as well as other gear that require a dependable electrical power source. The three phases are usually labeled A, B, and C, and every phase has its very own conductor or wire.

This is only attainable (for K5) in the event the Usually closed contacts of K1 are shut due to interlocking. Similarly, K3 is just energized when the Usually open contacts of K5 modify their condition from Open to Closed.
In a very wound rotor, the rotor windings are much like the stator windings and they are connected to external circuits via slip rings and brushes. This permits for improved starting torque and pace Manage but includes increased servicing necessities.
The way with the torque is dependent upon the relative route with the magnetic fields. Inside a three-phase induction motor, the rotor often tries to follow the rotating magnetic industry with Three Phase Motor the stator.
The rotor will be the rotating Section of the motor, which includes conductive bars which have been shorted at each close by stop rings. The rotor is often possibly a squirrel cage rotor, that's the most common style, or even a wound rotor.
Slip ring motors are usually utilized for products like plunger pumps, cranes, conveyors, crushers, or elevators. Additionally, slip ring induction motors are commonly used for hundreds that need a really high Preliminary torque and usually for conditions the place the commencing current is very low.
