Working Model of Electric Motor
Working Model of Electric Motor (Product Code: SCL-423/108) is an open-construction DC motor model used as a demonstration model in the physics lab to show how electrical energy is turned into rotation. Built in an acrylic body, it has a 2-pole armature, a disc-type commutator and a removable permanent magnet, and runs on 6–8 V DC. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Electric Motor Model Used For?
With the model connected to a 6–8 V DC supply through its 4 mm sockets, students watch the armature turn and can follow each step. Current enters through the phosphor bronze brushes, the disc commutator reverses the current in the coil every half turn, and the force between the coil and the permanent magnet keeps the rotation going. Because nothing is enclosed, the teacher can point to each part while it runs.
Taking away the permanent magnet stops the motor, a quick way to show that the magnetic field is essential, and reversing the supply leads reverses the direction of rotation. Keep the supply within 6–8 V, clean the commutator gently if running becomes uneven, and handle the acrylic body with care, as with any physics demonstration kit.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this electric motor model. The model is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, institutions, dealers and importers. If a brush, magnet or other part needs replacing later, the manufacturer itself handles the request, so ask us. See the ScienceLab company profile.

Frequently Asked Questions
What voltage does the Working Model of Electric Motor need?
The Working Model of Electric Motor (SCL-423/108) operates on 6–8 V DC. A low-voltage DC source such as a battery eliminator or cells is connected through the model's pair of 4 mm colour-coded sockets, which link to the phosphor bronze brushes.
Which parts can students see in the motor model?
Every part of the Working Model of Electric Motor is visible because the construction is completely open: the 2-pole armature wound with enamelled copper wire on a plastic bobbin, the disc-type commutator, the phosphor bronze brushes and the removable permanent magnet, all in an acrylic body.
Why is the permanent magnet removable?
The removable permanent magnet on the Working Model of Electric Motor lets teachers show that a motor needs a magnetic field: with the magnet taken away, the armature stops. It also makes the field source easy to identify and discuss during the lesson.
How should the Working Model of Electric Motor be looked after?
Run the Working Model of Electric Motor only within 6–8 V DC, disconnect it after use, and keep the commutator and brushes free of dust. Clean the acrylic body with a soft damp cloth rather than solvents, and store the model covered.
Who manufactures the Working Model of Electric Motor?
The Working Model of Electric Motor is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Schools, dealers and importers buy directly from the manufacturer, which also handles repeat orders.
Can the motor model be ordered with a dynamo model?
Yes, the Working Model of Electric Motor can be quoted together with the Working Model of Dynamo, which uses the same basic assembly mounted on a base plate. Send the quantities you need through the ScienceLab contact page for a manufacturer's quotation.
