Brushes do not transfer power. They allow current to flow. The current flowing through the windings creates a magnetic field which interacts with the permanent magnets. A turning force is generated, torque. The rate at which that torque is produced is power.
Jim. John Thorpe of Pomona was the first to sell Fiddlesticks. I have one of his all-brass ones I bought in the early '70s, as well as a Sonic with the black barrel which were sold much later. You can calibrate them using a gram scale.
2:01 Answers B and C are the same "Higher top end and less torque"
Good thing you don't have to wind your own motors today.

Yes they do. Brushes transfer electric power.

There were two I didn't know as they related to products from way before I got into this hobby.
Good recap. But the Kemtron was far from one of the first motors used in slot racing... lots of motors preceded it, especially Pittman.
