DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
Is DC motor and DC generator same?
DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. … DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
What is DC generator principle?
A DC generator operates on the principle of Faraday’s laws of electromagnetic induction. According to Faraday’s law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor.
What are the advantages of DC motor?
Good speed control
DC motors offer highly controllable speed. By changing the armature or field voltage it’s possible to achieve wide speed variation and with this level of controllability, DC motors offer the precision required by a wide range of industry applications.
How do you build a DC motor?
What You Need:
- Insulated copper wire.
- Black permanent marker (such as a Sharpie)
- Small neodymium disc magnets.
- D-size battery.
- Battery holder (sticky tack or modeling clay can be used instead)
- Large rubber band (not needed if using a battery holder)
- 2 large paperclips.
How do you identify a DC motor?
Look for the commutator & brushes and salient field system to confirm. (iii) has 5 terminals, then it is a AC synchronous motor (3 for stator and 2 for field). Look for 2 slip rings for rotor dc supply. (iii) has 4 terminals, then it may be a DC motor, in which case look for the commutator & brushes to confirm.
