When have seen that rotor rotates in the same direction as that of R.M.F. but in steady state attains a…
Uptill now, we have seen torque – slip characteristics of an induction motor. To compare the performance of induction motor…
In this type of construction, rotor winding is exactly similar to the stator. The rotor carries a three phase star…
The rotor core is cylindrical and slotted on its periphery. The rotor consists of uninsulated copper or aluminium bars called…
From the previous article, it is clear that if excitation is varied from very low (under excitation) to very high…
Hello Engineers. 1. In an alternator, voltage drops occurs in (A) armature resistance only (B) armature resistance and leakage…
There is a specific procedure of connecting synchronous machine to infinite bus bars. Infinite bus bar is one which keeps…
When synchronous motor is over excited it takes leading p.f. current. If synchronous motor is on no load, where load…
In the applications where high starting torque and constant speed are desired then synchronous induction motors can be used. It…
1. Direction of Rotation of Motor The magnitude of the force experienced by the conductor in a motor is given…
