Electric Motor Model
Product Code : SCL-PLE-11670
Quick Answer: The Electric Motor Model is a permanent-magnet DC motor with a multi-turn copper armature and split-ring commutator that runs on 3–6 V DC and carries a Newton’s colour disc.
Last updated: 18 October 2026
Key Features
- Multi-turn insulated copper coil on a balanced rotor.
- Permanent magnets provide the field.
- Split-ring commutator with brushes keeps the coil turning one way.
- Newton’s colour disc fitted for colour-mixing demonstrations.
- Low-voltage DC operation in the 3–6 V range.
Technical Specifications
| Specification | Value |
|---|---|
| Armature | Multi-turn insulated copper coil on a balanced rotor |
| Magnets | Permanent magnets |
| Commutation | Split-ring commutator with brushes |
| Accessory | Newton’s colour disc |
| Supply | 3–6 V DC |
How It Is Used
Connected to a low-voltage DC supply, the coil turns between the magnets as described by Fleming’s left-hand rule, and the commutator reverses the current each half-turn to keep it spinning. With the colour disc spinning, the coloured sectors blend towards white through persistence of vision.
Frequently Asked Questions
What voltage does the Electric Motor Model run on?
It works from a low-voltage DC supply in the 3–6 V range.
Why does the Electric Motor Model carry a colour disc?
The motor spins a Newton’s colour disc, so the same model can show the coloured sectors blending into white.
