What is the difference between a dynamo and an electric motor?

Solution. Although the construction of both dynamo and motor is same, there is the difference in the basic function they perform. A motor utilises the energy of an electric current to cause rotation of coil and shaft while a dynamo converts the mechanical energy from rotation to electric current using the principal of electromagnetic induction.

Generators and Dynamos

Generators, Dynamos, and Batteries are the three tools necessary to create/store substantial amounts of electricity for human use. Batteries may have been discovered as early as 248 BC. They simply use chemical reaction to make and store electricity. Scientists experimented with the battery to invent the early incandescent lamp, electric motors ...

Motor–generator

A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of ...

Difference Between Motor And Generator, Working Principles

In a motor, the energy flow is unidirectional, moving from electrical to mechanical. Electrical energy is supplied to the motor, resulting in the generation of mechanical motion. A generator operates in the reverse direction. It converts mechanical energy into electrical energy, with the primary output being electrical power.

A simple dc generator consists of a coil of wire rotating in a magnetic field. However, it uses a split ring commutator rather than the two slip rings found in alternating current (ac) generators.

DC motor

OverviewElectromagnetic motorsCommutationPermanent magnet statorsWound statorsSee alsoExternal links

A coil of wire with a current running through it generates an electromagnetic field aligned with the center of the coil. The direction and magnitude of the magnetic field produced by the coil can be changed with the direction and magnitude of the current flowing through it. A simple DC motor has a stationary set of magnets in the stator and an armature with one or more windings of insulated wire wrapped around a soft iron core that concentrates the magnetic field. …
