Product Code : SCL-PLE-11346

Scientifc Equipment Demonstration DC Motor is an educational physics laboratory apparatus designed to demonstrate the working principle of a direct current motor. It is suitable for school physics laboratories, STEM classrooms, college practical labs, electricity and magnetism lessons, and teacher-led demonstrations.

This apparatus helps students understand how electrical energy is converted into mechanical energy. By observing the rotation of the coil or armature in a magnetic field, students can clearly learn the role of current, magnetic force, commutator, brushes, and Fleming’s left-hand rule in the operation of a DC motor.

Product Description

The Demonstration DC Motor by Scientifc Equipment is a classroom-ready model used to explain the basic construction and operation of a DC motor. The apparatus generally includes a coil or armature, permanent magnet or field magnet, commutator, brushes, connecting terminals, support frame, and base arrangement as per model configuration.

When a suitable low-voltage DC power supply is connected, electric current flows through the coil placed in a magnetic field. The interaction between the current and magnetic field produces a force on the coil, causing it to rotate. This visible rotation helps students understand the motor effect and the conversion of electrical energy into rotational motion.

Scientifc Equipment Demonstration DC Motor is useful for teaching electromagnetism, motor working principle, current direction, magnetic force, torque, energy conversion, and practical applications of electric motors in everyday devices.
