Similar to d.c. machine where there is no constructional difference between a generator and motor, There is no difference between the…
Synchronous motor works on the principle of the magnetic locking. When two unlike poles are brought near each other, if…
From the torque equation, it is clear that torque depends on slip at which motor is running. The supply voltage…
The value of ? for which the mechanical power developed is maximum can be obtained as, Note : Thus when Ra is negligible, ?…
It is seen in the generation action, that when a conductor cuts the lines of flux, e.m.f. gets induced in…
Similar to the d.c. generators, the d.c. motors are classified depending upon the way of connecting the field winding with…
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…
