GENERATOR:
- converts mechanical energy to electrical energy.
- It works on flemings right hand rule.
- It works on the princple that an EMF is induced when a changing magnetic field links with the conductor. This emf is directly proportional to the rate of change of magnetic field linking the conductor.
- converts electrical energy to mechanical energy.
- works on flemings left hand rule.
- It works on the princple that a mechanical force is experienced by the current carrying conductor when placed in magnetic field.

What is the difference between Variable Speed Drive and Variable Frequency Drive?
A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFD's vary the speed of an AC motor by varying the frequency to the motor. VSD's referring to DC motors vary the speed by varying the voltage to the motor.
Why current is supplied to DC motor?
What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.
What is the difference between ac Hall effect and dc Hall effect?
ac hall effect always rises and dc is always in steady state.................
What is difference between ac and DC bulb?
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
What is armature reaction in dc machines?
The armature reaction is the interaction between armature flux and field flux when current is introduced to a dc motor. It results in a cross-magnetizing effect and a demagnetizing effect.
What are the main parts of a DC servo motor?
Motor inside and outside movement and non movement material
What is the difference between a DC motor and an AC motor?

What are the Difference between dc motor and dc generator?
a motor Will do work by consuming power a generator is just the opposite
What is the difference between Counter-electromotive force and back emf?
They are Same for dc motor
What is AC motor and DC motor?
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
What is the difference between AC and DC choke?
There is no difference between AC AND DC chockes
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What is the main difference between dc motor and dc servo motor?
A DC motor is an electric motor that turns on the application of a DC current. A DC Servo motor is similar but it produces a DC current from a mechanic movement of the armateur or may also produce small movement from the application of low current.. An example of a servo motor is as was used in steering gears and auto pilots. The physical turning of the wheel either caused a current to flow or caused an inbalance in the electrical systems, this causes a counter action to restore the original position.
What is the difference between DC motors and DC generator?
A generator turns mechanical (or other) energy into electricity. A motor does the exact opposite, turning electrical energy into mechanical energy (e.g. motion).
Why would a 110 motor runs slowly backwards?
It depends on if the motor is an AC motor, or DC motor. DC motors only run backwards when the voltages get crossed between + and -.
What is the time difference from dc and Ecuador?
There is no time difference between Washington, DC, USA and Quito, Ecuador
