What is an Electric Motor? An electric motor can be defined as; it is one kind of machine used to convert the energy from electrical and mechanical. Most of the motors work through the communication among the electrical current and magnetic field of the motor's winding for generating force in the form of shaft rotation. These motors can be triggered by a DC source or AC source.

The word "motor" refers to any power unit that generates motion, that is a "prime mover", while "electric motor" refers to a "prime mover using electricity." In English, this prime mover using electricity is customarily called an electric motor.

Mar 29, 2018· Motor is a device which converts the electric energy into mechanical energy, It depends on the torque due to the flow of the electric current in a coil which can rotate in a magnetic field, The electric motors are classified into two different categories which are Direct Current (DC) motor & Alternating Current (AC) motor, DC motor is an electric motor which runs on direct current power.

Oct 03, 2020· Structure of DC Motor PARTS OF THE STATOR:-YOKE: The yoke or outer frame provides coverage to a dc motor. It is made up of cast steel for large dc motors. And of cast iron for small dc motors. The yoke is used in DC machine because: A) It provides mechanical support to poles. B) Acts as a protective cover against mechanical damage.

Sep 12, 2020· Principle and structure of electric motor. The winding is wound on the iron core support. Because the winding and the iron core are fixed, it is called the stator. In the middle of the stator is a cage-shaped rotor. The operation of the rotor can be seen as being driven by the rotating magnetic field generated by the winding, which has a ...

What is DC Motor? A DC motor is an electric motor that runs on direct current power. In an electric motor, the operation is dependent upon simple electromagnetism. A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field, it will encounter a force proportional to the current in the conductor and to the strength of the external magnetic field.
