Advantage over?
DC motors used to be preferred where precise control and variability of rotation speed were desired, but modern motor design and electronic controls have very largely negated that advantage.
A series motor is useful mainly for driving a tram or bus because the torque is proportional to the square of the current. That means that a very large torque is produced for starting up and no gearbox is necessary. The motor is started with a current-limiting resistor which is switched down by the driver or automatically as the speed builds up.

What is the major advantage of a compound DC generator?
The compound DC motor has the advantage of both, constant speed feature of the shunt motor and the capability to handle high starting torque feature of series motor.
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
What is difference between advantage and disadvantage AC and DC power transmission line?
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage

What motors is used in railway engines for traction?
dc series motor :A series-wound DC motor has a low resistance field and armature circuit. Because of this, when voltage is applied to it, the current is high. (Ohms Law: current = voltage/resistance). The advantage of high current is that the magnetic fields inside the motor are strong, producing high torque (turning force), so it is ideal for starting a train. The disadvantage is that the current flowing into the motor has to be limited, otherwise the supply could be overloaded and/or the motor and its cabling could be damaged.
