Mention the Starters used to start a DC motor. Last Answer : Two point Starter Three point Starter Four point Starter ...
Name any two starters which can be used with only slip-ring induction motor Last Answer : Rotor resistance starter Solid state rotor resistance starter...
Is it possible to include/ Exclude external resistance in the rotor of a Squirrel cage induction motor?. Justify Last Answer : No it is not possible to include/ Exclude external resistance in the rotor of a Squirrel cage induction motor because, the rotors bars are permanently short circuited by means of circuiting rings (end rings) at both the ends. i.e. no slip rings to do so....
What are the effects of increasing rotor resistance in the rotor circuit of a 3-phase induction motor as starting? Last Answer : Due to addition of resistance in rotor circuit by the stator not only reduces the staring current, in addition to that the starting torque developed than those given by DOL starting....
How do you start an Induction motor? Last Answer : The stator windings when supplied with 3-phase currents produce a magnetic flux, which is of constant magnitude but which revolves at synchronous speed. This revolving flux induces an AMF in the rotor by mutual induction...
