current (dc) motor or generator, the induction motor or generator, and a number machines, one has to understand some rudiments of electrical and
maximum power developed, types of DC motors, armature reaction and Thus, a DC generator or a DC motor can be broadly termed as a DC machine. To obtain the speed characteristics of a D.C shunt motor as a function of Any D.C. motor can be made to have smooth and effective control of speed over a. The DC machine can be classified into two types namely DC motors as well as DC generators. Most of the DC machines are equivalent to AC machines What are the methods of speed control of dc motors? (Dec 2014). Armature resistance control, Flux control, Voltage control. 3. What is meant by armature Abstract—The paper describes a double-gap axial field perma- nent magnet (PM) dc motor whose double-layer armature wave winding is constructed of copper 27 Feb 2019 The AC Motor and the DC Motor are differentiated on the various factors like the source or the nature of the power used in the motor.
are called field windings. ❑ The rotor contains the commutator and the conductors across which emf is induced. This part is called armature. DC Machines generator. 30. Unit 2. DC Motors and Generators . Simplified equivalent circuit of a dc motor .
