Demonstration, Electric Motor Manufacturer,Supplier and Exporter in India

Demonstration, Electric Motor (Product Code: SLE/PHY/152) is a simple DC electric motor used to show how a current-carrying armature turns in a magnetic field in school and college physics classes. Its 2-pole armature is wound with enamelled copper wire, the field comes from a removable bar magnet, and it 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 Demonstration Electric Motor Used For?

Because every working part is on view, students can follow the current from the 4 mm sockets through the phosphor-bronze brushes and the disc-type commutator into the armature windings. The teacher can then explain how the commutator reverses the current in the 2-pole armature every half turn, so the turning force keeps acting in the same direction. It links directly to the motor effect and Fleming's left-hand rule in electromagnetism lessons.

The removable bar magnet makes simple investigations possible. Turning the magnet round, or swapping the supply leads, reverses the direction of rotation, and taking the magnet away shows that without a field there is no turning force. Keep the supply within 6–8 V DC and switch off before handling the armature. It is a dependable item for any physics demonstration kit in India or overseas.

What to Specify When Ordering

• Number of motors, for a single teacher demonstration or for several student groups.
• Whether you need a low-voltage supply that can provide 6–8 V DC.
• 4 mm connecting leads for the brush sockets.
• Whether the Demonstration Dynamo Model should be quoted as well, to teach motors and generators together.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this demonstration motor and makes it at its own licensed factory at Saha, Ambala, Haryana, India. The company is a registered MSME with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and overseas orders are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT. Schools, colleges, dealers and importers buy directly from the maker — ask us about spare bar magnets or brushes when you order. Company details are on our profile page.

Frequently Asked Questions

What supply does the Demonstration, Electric Motor need?
The Demonstration, Electric Motor operates on 6–8 V DC. The supply is connected through a pair of 4 mm sockets that lead to the phosphor-bronze brushes, so any low-voltage laboratory DC source with 4 mm leads can be used.

Why is the bar magnet on the Demonstration, Electric Motor removable?
The removable bar magnet on the Demonstration, Electric Motor lets teachers show the role of the magnetic field. Reversing the magnet reverses the rotation, and removing it stops the turning force, which helps students connect the motor effect to the field direction.

What type of commutator does the Demonstration, Electric Motor have?
The Demonstration, Electric Motor has a disc-type commutator with phosphor-bronze brushes. It reverses the current in the 2-pole armature every half turn, keeping the turning force in one direction so the motor rotates continuously on DC.

How is the Demonstration, Electric Motor different from the Demonstration Dynamo Model?
The Demonstration, Electric Motor is the basic DC motor on its own. The Demonstration Dynamo Model uses the same basic assembly but adds a base plate, hand-drive pulley, belt and indicator lamp so it can be cranked by hand as a generator.

Who manufactures the Demonstration, Electric Motor?
The Demonstration, Electric Motor is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and spare-part questions are handled directly by the manufacturer.
