The principles of working of an électric moteur

Principle

Students will construct various different motor designs using the motor model kit. Using a bar magnet on the model turns it into a DC motor with a direction of rotation dependent on the direction of the current. If an electromagnet is used for the stator field, as s ...

Conversion of electrical energy into mechanical energy

Principle

A motor that raises a load, i.e. converts electrical energy into mechanical energy, is a familiar everyday sight. The special feature of this set-up is that it can be used to generate electrical energy again directly from the descending weight. That electrical e ...

The direct current permanent magnet électric moteur

Principle

Electric motors for not too high power and simple dynamos are frequently based on the basic principle that an electromagnet rotates in the field of a permanent magnet (or several of them).

Tasks

Examine the behavio ...

The series moteur

Principle

The stator field of an electric motor can be generated by an electromagnet, which is then called the excitationwinding. In series motors, the excitation winding is switched in series with the armature winding of the rotor.This type of motor is sometim ...

Magnetic field of a coil

Principle

This experiment is designed to show the magnetic property of a coil and so bring an understanding of the role it plays in an electric motor or generator.

Task

Compare the magnetic field of a permanent magnet with th ...

Conversion of electrical energy into kinetic energy

Principle

This experiment explains how electric energy can be converted to energy of motion in an electric motor.

Task

Examine the behaviour of a coil that is pivoted so that it can turn in the magnetic field of a U-shaped ma ...

Commutator

Principle

This is the last step towards being able to understand how a complete electric motor is constructed. It
teaches how a current reverser works and which function it undertakes in an electric motor.

Task

Examine ...

Synchronous motor

Principle

This experiment is to demonstrate the mode of functioning of a synchronous motor.

Task

Set up a motor that can be driven by alternating current. First with an electromagnet as rotor and a permanent magnet as stator ...
