Base Plate with Electric Motor with Propeller and Newton's Color Disk

Product Code : SCL-EI-10646

The Newton Color Disk with Electric Motor (base plate, motor, propeller, and colour disk assembly) is a precision optics and mechanics teaching apparatus manufactured and exported by Lab Glassware Manufacturer, based in Ambala, Haryana, India, in continuous operation since 1982. This apparatus is supplied to school and university physics laboratories across Central Europe, including Poland, the Czech Republic, Hungary, and Slovakia, supporting classroom demonstrations of additive colour mixing and rotational motion.

Quick answer: The Newton Color Disk with Electric Motor spins a seven-segment colour disk at speed on a low-voltage DC motor so that the individual spectral colours blend together by persistence of vision into an off-white appearance, demonstrating that white light is composed of the colours of the visible spectrum; the same base plate and motor can also drive an included three-blade propeller for a simple air-displacement demonstration.

Key Features

• Optically calibrated disk: a 150 mm diameter disc divided into seven balanced colour segments for clean light synthesis.
• Dual demonstration capability: works as both a light-mixing assembly and a rotational-motion demonstration tool via the included propeller.
• Heavy-duty base plate: an insulated, impact-resistant base plate that resists bench slippage and electrical grounding errors.
• Low-voltage efficiency: runs safely on standard 3V to 6V DC power sources commonly found in classrooms.
• Compatible with modular kits: works alongside other Electronic Instruments and multi-component energy-conversion setups.

What's Included

• 1 x Insulated laboratory base plate with pre-mounted DC motor
• 1 x Segmented Newton color disk
• 1 x Lightweight three-blade plastic propeller attachment
• 2 x Standard electrical connection leads

Applications / Uses

• Demonstrating Isaac Newton's historical spectrum recombination theory to students.
• Showing the persistence-of-vision principle in introductory optics lessons.
• Comparing additive colour mixing with subtractive colour theory during physics lectures.
• Serving as a rotational-motion demonstration unit using the propeller attachment.
• Illustrating basic rotational frequency and mechanical work alongside other STEM kits.

How to Use the Newton Color Disk with Electric Motor

1. Place the base plate firmly onto a clean, flat laboratory workbench.
2. Slide the segmented Newton color disk onto the drive shaft of the DC motor, making sure it sits flush.
3. Connect the positive and negative terminal leads from a 3-6V DC laboratory power supply to the corresponding inputs on the base plate.
4. Slowly increase the voltage until the rotational speed blends the distinct colours into an off-white appearance.
5. To switch experiments, power down the supply completely, remove the disk, and install the propeller to observe air-displacement principles.

Safety note: Keep clothing, hair, and fingers away from the apparatus while the motor is spinning at high speed to avoid minor contact injury.

Care & Maintenance

• Clean the face of the colour disk using a dry, anti-static microfiber cloth to prevent colour degradation from oil residues.
• Avoid lubricating the internal motor housing unless explicitly directed by the manufacturer's technical guidance.
• Store the product inside a low-humidity storage case away from direct sunlight to preserve the colour segment pigments.

Part of the Motor and Optics Teaching Range

The Newton Color Disk with Electric Motor uses the same class of low-voltage DC motor found in the standalone Electric Hobby Motor and the Electric Motor Kit, but pairs it with an optics accessory rather than a general-purpose circuit-building motor. Schools teaching both electricity and optics from the same equipment range can combine this apparatus with those motor kits for a fuller demonstration sequence covering electrical energy conversion, rotational motion, and light theory.

Why Choose Lab Glassware Manufacturer

Lab Glassware Manufacturer is a manufacturer and exporter of educational and technical scientific equipment based in Ambala, Haryana, India, serving Poland, the Czech Republic, Hungary, Slovakia, and other Central European markets. The company applies internal quality checks to its motors, base plates, and optical accessories, and supports institutional buyers with export documentation and bulk-order logistics. Buyers should confirm final electrical ratings and dimensions from the approved datasheet before bulk supply or tender submission.

Frequently Asked Questions

What is the Newton Color Disk with Electric Motor used for?
It is used in science classrooms to demonstrate optical colour blending, showing that white light is composed of the primary colours of the visible spectrum.

What input voltage does this laboratory motor require?
The motor operates safely on low-voltage direct current ranging from 3V to 6V DC, which can be provided by standard lab power supplies or battery packs.

Does the spinning disk look perfectly white?
The disk blends to an off-white or light grey hue because of the pigments used on the printed surface and ambient lighting during the demonstration.

Can students safely switch between the disk and the propeller?
Yes, the interchangeable parts slide onto the motor shaft easily; however, changes must only be made while the power supply is switched off.

Is this apparatus suitable for mobile STEM kits?
Yes. Its compact base plate and durable, lightweight components make it suitable for distributed student laboratory experiments.
