Large Motor/Generator
Large Motor/Generator (Product Code: SCI-1531/014) is a dual-purpose DC machine used either as a driving unit or as a dynamo in physics lessons on motors, generators and energy conversion. It comprises a 2 to 6 V DC motor fitted with a 15 mm diameter V pulley and comes with a driving belt, so it links easily to other apparatus, a useful piece of physics lab equipment for schools. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Large Motor/Generator Used For?
Connected to a low-voltage DC supply, the machine runs as a motor and, through its V pulley and belt, drives other apparatus. Turned by an external drive instead, it works as a dynamo and produces a voltage that students can read on a meter. Showing the same machine doing both jobs is one of the clearest ways to explain that motors and generators share the same principle, run in opposite directions of energy conversion.
For quantitative work, pair it with a smaller motor/generator: drive one with the other, meter the voltage and current on each side, and compare power in with power out to discuss losses and efficiency between larger and smaller machines. Keep the supply within the 2 to 6 V range, align the belt so it runs true, and avoid over-tightening it, which loads the bearings and wastes power.
What to Specify When Ordering
- Whether you also need the Small Motor/Generator for input/output comparison experiments.
- The number of units for your demonstration bench or student groups.
- Any DC supply and meters you want quoted, checked against the 2 to 6 V rating.
Supplier
Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies the Large Motor/Generator from Ambala, Haryana, India, sourcing this DC motor unit for school and college physics laboratories. It can be quoted together with the Small Motor/Generator, meters and a DC supply, so a complete energy-conversion setup arrives in one delivery. For vendor registration, the supplying company holds Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT. See the ScienceLab profile page for more.

Frequently Asked Questions
What voltage does the Large Motor/Generator run on?
The Large Motor/Generator is built around a 2 to 6 V DC motor. Run it from a low-voltage DC supply within that range; exceeding the rated voltage can overheat the windings and shorten the life of the machine.
Can the Large Motor/Generator be used as a generator?
Yes. The Large Motor/Generator is intended for use either as a driving unit or as a dynamo. When its pulley is turned by another motor or a hand drive, it generates a voltage that can be measured with a voltmeter.
What is supplied with the Large Motor/Generator?
The Large Motor/Generator comprises the 2 to 6 V DC motor with a 15 mm diameter V pulley and is supplied with a driving belt. A power supply and meters are not listed, so ask us if you want them quoted.
How is the Large Motor/Generator used with the Small Motor/Generator?
The Large Motor/Generator and the Small Motor/Generator are belted together and each is driven in turn by the other. Metering voltage and current on both lets students compare power input and output and discuss efficiency.
Who supplies the Large Motor/Generator?
The Large Motor/Generator is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, which sources the unit for schools, colleges, institutions, dealers and importers. Quotations and repeat orders are handled directly by the company.
Is the Large Motor/Generator available in bulk or for export?
Yes. ScienceLab supplies the Large Motor/Generator to schools, colleges, institutions, dealers and importers in India and international markets. Send the product code SCI-1531/014, the quantity and the destination to receive a quotation.
