Take the DC Motor Theory (DC Electric Circuits) worksheet. These questions & answers will help you master the topic!
20 mar 2013 · Key learnings: DC Motor Definition: A DC motor is defined as a device that converts direct current electrical energy into mechanical energy. Stator and Rotor: The stator is the stationary part with field windings, and the rotor is the rotating part causing mechanical motion.
DC Motor Questions and Answers 1. Starters are used with D.C. motors because (a) these motors have high starting torque. (b) these motors are not self-starting. (c) back e.m.f. of these motors is zero initially. (d) to restrict armature current as there is no back e.m.f. while starting. Answer: (d) 2.
1 paź 2024 · The d.c. motor. The motor effect can be used to create a simple d.c. electric motor. The force on a current-carrying coil causes it to rotate in a single direction. A simple d.c. motor consists of. a coil of wire (which is free to rotate) between the poles of a permanent magnet. a split-ring commutator and brushes connected to a source of d.c.
