What is the function of rotor winding?
rotor winding is of the squirrel-cage type where solid conductors in the slots are shorted together at each end of the rotor iron by conducting end rings. In such machines there is no need to insulate the conductors from the iron.
What is a function of electric motor?
An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
What is difference between armature and rotor?
It is located inside the stator and its objective is to rotate so that in turn the motor shaft or generator rotates. So basically, the rotor consists of a field magnet which rotates while the rotor remains stationary and on the other hand the armature carries current and is stationary and part of the stator.
What is the difference between shaft and rotor?
The rotor shaft , more commonly called the “mast” is the vertical sharton which the rotor head and blades are attached.it comes up from the transmission and it is what spins the rotor and supports the entire flight loads of the rotor down into the helicopters structure.
How is rotor current calculated?
The frequency of the rotor current fr = Ns x P/120, so fr = 0 if the slip is zero. If the operating speed is zero, Ns = N and the frequency of the rotor current is the same as the frequency of the stator current . f = source frequency in Hz.
What is rotor speed?
Rotor speed depends, in part, on rotor diameter. Rotor speeds typically lie in the 120–210 m/s range, but mostly between 150 and 190 m/s, with a tendency to be higher with a smaller rotor diameter .
What do you mean by rotor?
1a : a part that revolves in a stationary part a brake rotor. b : the rotating member of an electrical machine. 2 : an assembly of rotating blades that supplies lift or stability for a rotorcraft.
