Electric Motor (kit)

Product Code : SCL-EI-10610

Quick answer: The Electric Motor Kit is a student apparatus that demonstrates the working principle of a simple DC motor, letting learners assemble and observe how a current-carrying coil in a magnetic field produces rotation, torque, and the conversion of electrical energy into mechanical motion.

Key Features

• Student electric motor kit for demonstrating motor principle and electromagnetism
• Shows conversion of electrical energy into mechanical motion
• Useful for teaching magnetic force, torque, current direction and rotation
• Supports lessons on coils, magnets, commutators, brushes and motor contacts
• Suitable for school physics labs, electronics classrooms, STEM kits and exhibitions
• Can be used with compatible batteries or regulated low-voltage DC power supplies
• Helps students assemble, observe, troubleshoot and discuss motor operation
• Reusable demonstration apparatus for repeated practical sessions

Applications / Uses

• Demonstrating the working principle of a simple electric motor
• Teaching force on a current-carrying conductor in a magnetic field
• Explaining torque, polarity, commutation and direction of rotation
• Showing electrical-to-mechanical energy conversion in STEM classes
• Using with Basic Electrical Circuits lessons
• Pairing with a Universal Plugboard for modular circuit demonstrations
• Supporting energy-conversion lessons with SEG Energy Conversions 1

How to Use the Electric Motor Kit

• Place the kit on a dry, stable, insulated laboratory bench
• Identify the coil, magnet, axle, supports, commutator, brushes and terminals
• Assemble the rotor or coil according to the supplied instruction sheet
• Position the magnet so the coil can rotate freely within the magnetic field
• Connect the terminals to the confirmed low-voltage DC power source
• Check that the rotor spins freely without rubbing the frame or magnet
• Switch on the power and observe rotation, speed, direction and contact action
• Switch off power before adjusting coil position, magnet position or wiring

Safety note: Use only with a confirmed low-voltage power source under teacher supervision. Do not connect the kit to mains electricity, short-circuit the supply, touch overheated wires, or place strong magnets near pacemakers or sensitive electronic devices.

Care & Maintenance

• Keep the coil, contacts, magnet, terminals and base clean and dry
• Inspect brush contacts, commutator surface, wire insulation and moving parts before use
• Do not bend the axle, crush the coil, drop magnets or force the rotor
• Remove batteries before long-term storage if a battery holder is supplied

Building an Electromagnetism Teaching Module

Physics departments teaching electromagnetism often pair the Electric Motor Kit with a Coil with 400 Turns for standalone coil experiments and the Galvanometer Attachment for Student Transformer for measuring induced current, building a coherent progression from basic circuits through motor action and transformer induction.

Frequently Asked Questions

What is an electric motor kit used for?
An electric motor kit is used to demonstrate how a current-carrying coil in a magnetic field produces rotation and converts electrical energy into mechanical motion.

Is this electric motor kit suitable for school students?
Yes. It is suitable for supervised school and STEM use when operated with the confirmed low-voltage power source and teacher guidance.
