Electric Motor Model

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. Key features 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 Student investigations Voltage vs. rotor speed Vary the DC supply voltage and observe how increasing or decreasing the voltage changes the rate of rotor rotation. Magnet polarity Reverse or reposition the permanent magnets and observe the effect on the direction and speed of rotor rotation. Current direction Swap the 4mm socket connections to reverse current flow through the rotor and observe direction reversal. Commutator action Observe how the commutator switches current direction each half-turn to sustain continuous unidirectional rotation.
