Demonstration Electric Motor – DC Model (KS3+)

This Demonstration Electric Motor is a clear, durable teaching model designed to illustrate the simplest form of a DC electric motor. Suitable for KS3 and above, it allows students to observe directly how electrical energy is converted into mechanical motion, making abstract physics concepts easy to understand.

The motor features a 2‑pole armature wound with enamelled copper wire and operates within a permanent magnetic field created by a removable bar magnet. A disc‑type commutator ensures continuous rotation, clearly demonstrating the role of commutation in DC motors. Electrical connections are made via a pair of robust 4mm sockets connected to phosphor bronze bushes.

Powered by a low‑voltage supply of 6–8V DC, the motor is safe for classroom demonstrations and student‑led investigations. Its exposed design makes it ideal for close inspection during teacher demonstrations and practical explorations of electromagnetism.
