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.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.
