Definition
AC generator is a mechanical device that converts mechanical energy into electrical power.
DC generator is a mechanical device that converts mechanical energy into electrical power.
In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction.
In an AC generator, the output current can be either induced in the stator or in the rotor.
In a DC generator, the output current can only be induced in the rotor.
electic motor and electri generator :
An electric motor is a machine that converts electrical energy to mechanical energy.
An electric generator is a machine that converts mechanical energy to electrical energy.`
Electric motor follows Fleming’s left-hand rule.
Electric generator follows Fleming’s right-hand rule.
The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field.
The working principle of generator is based on electromagnetic induction.
