An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What is the role of a simple motor?
These motors are known as actuators. The simple motor built in class uses a coil that is a temporary electromagnet. This coil gets the force to help create torque from the electrical current supplied by the battery.
Why does a simple electric motor work?
This simple electric motor works by the magnetic force F = IL x B. The magnetic field at both of these spots points in the same direction. … Thus, the magnetic force on the wire at opposite ends of the loop points in opposite directions, causing it to spin.
Why do we need electric motors?
Unlike engines that run on fossil fuels, electric motors don’t produce any of the associated needs for servicing and will continue to operate even in freezing temperatures making them ideal for commercial and domestic refrigeration. Electric motors also contribute to a safe and comfortable working environment.
How does simple motor produce electromagnetism?
Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
How can you explain the simple electric motor and generator?
A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
How do simple DC motors work?
A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil. … The commutator allows each armature coil to be energised in turn, creating a steady rotating force (known as torque).
What are the energy transformations of a simple electric motor?
An electric motor converts mechanical energy into electrical energy.
How is simple motors different from commercial motors?
A simple motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on a coil which rotates it continuously while in commercial motors, the coil is bound on a soft iron core which becomes magnetized and increase the length of the magnetic field …

What are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
