Dynamo Working Model Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4537
Jlab Export is a leading Dynamo Working Model Manufacturer,and suppliers in India
Dynamo Working Model (code EL-SLE-4537) is a hand-driven demonstration dynamo for physics labs: turning the handle drives the dynamo through a gear, and a bulb glows while it rotates. Its open-frame construction leaves every part in view, so students can follow how a real dynamo turns motion into electricity. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Dynamo Models?
| Model | How it is driven | Output shown by | Other listed features |
|---|---|---|---|
| This model (EL-SLE-4537) | By hand, through a gear | Glowing bulb | Open frame |
| Dynamo (AC/DC) - Motor Working Model | AC/DC motor driven | Glowing bulb | Open frame |
| Demonstration Dynamo Model | Rubber belt to a smaller dynamo pulley (step-up ratio) | Lamp; output sockets | Can also run as a motor on 6–8 V DC |
Choose this model when students should do the work themselves and feel that more effort gives a brighter bulb. The motor-driven version runs steadily for a whole-class demonstration, and the belt-drive demonstration dynamo adds output sockets and doubles as a motor.
What Is the Dynamo Working Model Used For?
A dynamo turns mechanical energy into electrical energy by electromagnetic induction: as the coil and magnet move relative to each other, the magnetic flux through the coil keeps changing and a voltage is induced, which drives a current through the bulb. Turning the handle faster changes the flux more quickly, so the induced voltage rises and the bulb glows more brightly — a direct, visible link between work done and electrical energy produced. With the open frame, a teacher can point out the coil, the magnet, the gear and the connections to the bulb, and explain how a slip-ring arrangement gives alternating current while a split-ring commutator gives direct current; the listing does not say which arrangement this model uses. The model supports lessons on electromagnetic induction and the AC generator in class 12 physics, the electromagnetism chapter of ICSE class 10, and energy-conversion topics in lower classes, as well as science exhibitions.
What to Specify When Ordering
- Drive type — this hand-driven model, or the motor-driven AC/DC version for continuous running.
- Quantity — the minimum order is 10 models.
- Companion models — an electric motor model shows the reverse energy change and makes a natural pair.
- Delivery — destination country, port or city and delivery terms for an export quotation.
Frequently Asked Questions
How does the Dynamo Working Model work?
By electromagnetic induction. Turning the handle drives the dynamo through a gear, the changing magnetic flux induces a voltage in the coil, and the bulb glows while it rotates.
Does it need batteries or a mains supply?
It is listed as hand driven, so the energy comes from turning the handle. No power source is mentioned in the listing.
Does it produce AC or DC?
The listing does not say. Ask JLab to confirm the output type if your lesson plan depends on it; the AC/DC motor-driven model is the related listing that names AC/DC.
Why does the bulb get brighter when the handle is turned faster?
Faster turning changes the magnetic flux through the coil more quickly, which induces a larger voltage and so a larger current through the bulb.
What information should an export enquiry include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements and any tender reference.
Who manufactures this model?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India, and quotes directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of physics demonstration models and school laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This dynamo model is assembled at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers buy from the maker directly; each model is visually inspected before dispatch, and repeat orders and replacement parts are handled by the manufacturer. JLab exports worldwide and can ship to buyers in every region — for instance Slovakia in Eastern Europe, Peru in South America, Hong Kong in East Asia, Bahrain in the Middle East and Austria in Western Europe. Tender information is on the JLab lab tenders page.
