Demonstration Motor AC/DC
Demonstration Motor AC/DC (Product Code: SLE/PHY/153) is a hand-wheel operated demonstration machine used to show the generation of alternating and direct current in physics classrooms and laboratories. Turning the hand wheel produces AC and DC at the same time, and LED diodes make the generated voltage visible to the whole class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the AC/DC Demonstration Motor Used For?
Students often find it hard to picture the difference between alternating and direct current, because both simply "make a bulb light". This model tackles that directly: as the hand wheel turns, it produces AC and DC together and shows each through LED diodes, so the class can compare the two outputs side by side. Since an LED lights only when current passes through it in one direction, it is a natural way to reveal how the generated output behaves.
A good routine is to turn the wheel slowly first so students can watch the LEDs closely, then faster to show how the output responds to speed. The demonstration supports textbook topics such as electromagnetic induction, generators and the role of the commutator, and it complements any AC DC circuits experiment kit used later in student practicals.
OEM Manufacturer
The Demonstration Motor AC/DC is built by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, acting as OEM (original equipment manufacturer). Production takes place at its own licensed factory at Saha, Ambala, Haryana, India, and the model is supplied factory-direct to schools, colleges, teacher-training institutes, dealers and importers. If an indicator or other part needs attention after years of classroom use, ask us — the request goes straight to the maker. Read about the company on our company profile.

Frequently Asked Questions
What does the Demonstration Motor AC/DC show?
The Demonstration Motor AC/DC shows the generation of alternating and direct current. When its hand wheel is turned it produces AC and DC simultaneously, and LED diodes represent each generated voltage, so students can compare the two outputs during a single demonstration.
Does the Demonstration Motor AC/DC need a power supply?
The Demonstration Motor AC/DC generates its own output when the hand wheel is turned, so the LED display of AC and DC generation works by hand. If you want to discuss other ways of using it, contact us before ordering.
Why does the Demonstration Motor AC/DC use LED diodes?
The Demonstration Motor AC/DC uses LED diodes because an LED lights only when current flows through it in one direction. That property makes LEDs a clear, simple way to represent the difference between the alternating and direct voltage being generated.
Which lessons is the Demonstration Motor AC/DC suitable for?
The Demonstration Motor AC/DC suits lessons on electromagnetic induction, generators, alternating versus direct current and the purpose of a commutator. It works as a teacher demonstration at the front of the class and as a hands-on station for small student groups.
Who manufactures the Demonstration Motor AC/DC?
The Demonstration Motor AC/DC is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own factory at Saha, Ambala, Haryana, India. Enquiries, quotations and repeat orders go directly to the manufacturer.
