Electric Motor Model With Newton Colour Disc Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4541
Jlab Export is a leading Electric Motor Model With Newton Colour Disc Manufacturer,and suppliers in India
Electric Motor Model With Newton Colour Disc (code EL-SLE-4541) is a motor-driven Newton colour disc used to show that white light is made up of the colours of the spectrum and is formed by additive mixing of those colours. The disc sits on a plastic base fitted with terminals for connecting the supply, so it spins under power rather than by hand. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Newton Colour Discs?
| Model | How the disc turns | Disc as listed | Base |
|---|---|---|---|
| This model (EL-SLE-4541) | Electric motor, with terminals for the supply | Newton colour disc (size not given in the listing) | Plastic |
| Newtons Color Disc | By hand, with a wheel and handle | 15 cm diameter | Wooden |
| Newton’s Color Disc Wheel On Stand | By hand, through a wheel on a pillar | 9 in (230 mm) wheel with the seven spectrum colours in wedges | Wooden |
| Newton Hand Disc Spin Model | Spun by hand | About 200 mm diameter; shows white light from a mix of primary colours | Not listed |
Choose this model when you want the disc to run from a supply, so the teacher can talk the class through the effect while it keeps spinning. The hand-turned discs suit rooms without a convenient supply, and the wheel-on-stand version is the one whose listing details the seven colour wedges.
What Is the Motorised Newton Colour Disc Used For?
It is a classroom demonstration of colour mixing. A Newton disc is divided into sectors in the colours of the spectrum; when it spins fast, the eye cannot follow the separate sectors and, through persistence of vision, adds them together, so the disc appears whitish. Teachers pair it with a glass prism: the prism splits white light into a spectrum (dispersion, part of the class 10 science chapter on the human eye and the colourful world), and the spinning disc shows the colours recombining. Because a small electric motor does the turning, the same set-up also shows electrical energy being converted into rotation — a useful link for physics lab equipment in schools in India and abroad.
Connect the terminals to the supply recommended by JLab, switch on and let the disc reach full speed before asking students to look. Expect a pale greyish white rather than brilliant white: painted pigments are not pure spectral colours and each sector reflects only part of the light falling on it. Keep fingers and loose sleeves clear of the spinning disc, switch off before touching it, and wipe the disc with a dry cloth so dust does not dull the colours.
What to Specify When Ordering
- Supply — the listing does not state the operating voltage, so ask JLab to confirm the supply the motor needs and whether a power source should be quoted with it.
- Quantity — the minimum order is 10 units; schools often order one per science room plus a spare.
- Companion items — add a glass prism, or a hand-turned Newton disc for student groups, to the same enquiry.
Frequently Asked Questions
What does this model demonstrate?
That white light is composed of the spectrum of colours and is formed by their additive mixing. When the motor spins the disc quickly, the coloured sectors blend in the eye and the disc looks whitish.
How is the disc turned, and is a power supply included?
An electric motor turns it. The disc is mounted on a plastic base with terminals for connecting the supply; the listing gives neither the operating voltage nor a power source as part of the item, so ask JLab to confirm the supply and quote a source if you need one.
Why does the spinning disc look grey-white instead of pure white?
Because paints are not pure spectral colours. Each sector reflects only part of the incident light, so the blended result is a pale grey-white; a brighter room light and a clean disc give the whitest effect.
How does it differ from the hand-turned Newtons Color Disc?
The hand-turned model has a 15 cm disc on a wooden base and is rotated with a wheel and handle. This model runs from a supply and sits on a plastic base, which leaves both hands free during the demonstration.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of school science and physics demonstration equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This colour-disc model is assembled at JLab’s own works instead of being sourced from a trader, so schools, dealers and importers deal with the manufacturer directly; every unit is visually inspected before it is packed, and repeat orders and replacement parts are handled by the same team. JLab ships worldwide — buyers in every region can order, for instance in Sudan (North Africa), Armenia (Eastern Europe), Serbia (Southern Europe), Trinidad and Tobago (Central America and the Caribbean) and Ethiopia (East Africa). Schools buying through a tender can find details on the JLab lab tenders page.
