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.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more.
I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things.
It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic.
I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together.
I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray.
Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know.
PRO:
* Very likable characters
* Lots of steamy scenes that are written very well
* The spelling and grammar are good
* The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens.
CON:
* Almost no interactions with any characters outside of Madison and the pack
* Nearly no plot. They meet, get together for a heat, agree to make it permanent, done
* Quite a few typos such as extraneous words, missing words and words out of order
THINGS TO KNOW:
* More steamy scenes than storytelling
* A lot of MM & MMM, some MFMM during heat
