Questions on sync motor
1. In an asynchronous motor, does the drawn current with the increasing mechanical load grow or decrease?
2. How is the difference between the revolutions of the magnetic field of the stator and the revolutions of the rotor called?
3. What is the meaning of switching the motor first into star and then into delta?
4. From what motor output is it recommended to carry out the Y/D start?
5. With what devices can the Y/D start be replaced?
6. How many times is the starting current with the connection in delta greater than with the connection in star?
7. Write why with the Y/D connection the contacts of all three contactors must never be connected.
8. If we have a 1 kW 3-phase motor, in which we do not know whether it is built for Y/D operation, we connect it in Y, or in D?
