Give the two basic speed control of DC shunt motor.
Answer Posted / soutrick chakraborty
we can control the speed of the dc shunt motor by two
methods. but at first we should know there are two type
speed, 1> base speed 2> top speed. for reach the base speed
we increase the armature voltage maximum , which is
mentioned in motor nameplate. and reach the top speed we
should decrease the feild flux, it means feild current,
which is also mentioned in motor name plate.

Define peak time.
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
