Electric Motor Model

Investigate the relationship between voltage supplied to the rotor and the polarity and position of magnets — a hands-on window into the principles powering every electric motor.

The Electric Motor Model (SE.EM1412-01) is a clear, open-construction demonstration motor designed for physics and STEM laboratories. By exposing the rotor, magnets, and commutator, students can observe exactly how electrical energy converts to mechanical rotation.

On applying 6V DC to the 4mm input sockets, the rotor begins rotating about its vertical axis. Students can then vary the supply voltage, reverse the connections, or reposition the magnets to directly observe how each variable affects rotor speed and direction — building a genuine conceptual understanding of electromagnetic motor principles.

• Open-construction model — rotor, magnets, and commutator fully visible
• Rotor rotates about vertical axis — clear, observable motion
• 6V DC supply via standard 4mm sockets
• Investigate effect of varying voltage on rotor speed
• Investigate effect of magnet polarity and position on rotation
• Commutator and brush contacts visible for circuit-switching study
• Sturdy base with integrated 4mm input terminals
• Ideal for secondary school physics and STEM curriculum
