specific applications. In most cases, regardless of type, electric motors consist of a stator (stationary field) and a rotor (the rotating field or armature) and operate through the interaction of magnetic flux and electric current to produce rotational speed and torque. DC motors are distinguished by their ability to operate from
DC Machines. DC currents are required for both its field winding. ( stator ) and armature winding (Rotor). DC machine mainly used as DC motors. DC motors is characterized by superior torque and a wide range of speed . D) Number of parallel circuits in this type of windings whatever the number of poles is always equal to

7 Jan 2015 The field of DC motors can be a permanent magnet, or electromagnets connected in series, shunt, or compound. Coupled with a DC drive, they provide.
DC Motor Applications. TECO-Westinghouse Motor Company DC motors are ideally suited to a multitude of industrial and marine applications in which high torque and variable speed are required. These applica- tions include ship propulsion, mine hoists and steel rolling mills. They also drive many other types of industrial
8 Application of d.c. motors. Some elementary principles of application alone are dealt with here. The focus is on the mechanical equation of dynamics which is reproduced here once again. TM ? TL = J dw dt. (43). Here TM and TL are the motor torque and the load torques respectively which are expressed as functions of ?.
speed/torque characteristics of d.c. motors are much more superior to that of a.c. motors. Therefore, it is not surprising to note that for industrial drives, d.c. motors are as popular as 3-phase induction motors. Like d.c. generators, d.c. motors are also of three types viz., series-wound, shunt-wound and compound- wound.

Brush-type DC Motor: has a mechanical brush pair on the motor frame & makes contact with a commutator ring assembly on the rotor in order to communicate current, i.e. to switch current from one winding to another, as a function of rotor position so that the magnetic fields of the rotor & stator are always at a 90o angle
Basics of Brushed DC Motors. - Four Types of Brushed DC Motors. 0 Principles of Operation. During this web-seminar I will discuss the main components of a brushed DC motor and how these components work together to function as a motor. We will also explore four types of brushed DC motors and compare common
