DC Series Motors

A DC motor is a type of electric motor which converts electric energy into mechanical energy. The forces that are produced by the magnetic field are what those common types of motors rely upon. Either electro-mechanical or electronic, all types of DC motors have some internal mechanism to change the current direction in part of the DC motors. As the DC motors could be powered from existing DC lighting power distribution systems, these motors were the first form of motors widely used. By changing the strength of the current in its field winding or by using a variable supply voltage, the speed of the DC motors can be controlled over a wide range.

Question

Q6-Indicate whether the following statements are true or false and correct the
false statements.
1- The characteristic (angular speed versus T) of a dc shunt motor is known as the

2- When a series d.c. motor is operate without load, the armature will not run
3- The generation of electricity achieved by moving a conductor in a magnetic field due
to the relation E= ILB
General questions
4- In series d-c generator the field winding will be constructed from high number of
turns and high cross-sectional area of wire.
5-Series motor maintains a more constant speed under varying load
6-The armature voltage of d.c series generator is not affected by load current.
7- In series d-c generator the field winding will be constructed from high number of
turns and high cross-sectional area of wire.
8- If field resistance of a d.c. shunt generator is increased beyond its critical value, the
generator output voltage will exceed its rated voltage
9-The inter pole winding is connected in parallel to field winding.
10- in de machine the interpole winding connected across the armature winding.
