Electric Motor Principle Apparatus

Product Code : SCL-EAE-11353

The electric motor principle apparatus is a physics demonstration apparatus used for showing how a current-carrying conductor or coil experiences force in a magnetic field and produces rotational motion. It is designed for schools, colleges, STEM labs, physics laboratories, electrical training rooms, and electromagnetism demonstrations.

Product Description

The Electric Motor Principle Apparatus by Lab Equipments Ambala is an educational electricity and magnetism teaching aid for explaining the basic working principle of a DC motor. It helps students observe how current, magnetic field direction, force, torque, and coil rotation are related in motor action.

This apparatus is suitable for teacher-led demonstrations, supervised student practicals, and introductory electrical engineering lessons. It connects textbook concepts such as Fleming’s left hand rule, magnetic force, commutation, armature rotation, and energy conversion with a visible classroom setup. Exact operating voltage, magnet type, coil construction, commutator arrangement, material, dimensions, and supplied accessories should be confirmed from the final datasheet before publication or procurement.

How to Use the Electric Motor Principle Apparatus

1. Place the apparatus on a clean, dry, and stable laboratory table.
2. Check that the coil, magnet, brushes, terminals, and rotating parts are correctly aligned.
3. Connect only the approved low-voltage power source specified in the supplied manual.
4. Switch on the circuit and observe whether the coil or armature rotates.
5. Identify the magnetic field direction and the current direction through the coil.
6. Use Fleming’s left hand rule to predict the force direction on each side of the coil.
7. Observe how the commutator or current-reversal arrangement helps maintain rotation, if included.
8. Disconnect power before changing connections, reversing polarity, or adjusting the setup.

Use the apparatus only under teacher supervision. Keep the setup dry, use only the approved low-voltage supply, avoid short circuits, and keep fingers, loose clothing, and wires away from rotating parts.

Care & Maintenance
