Scheerer, H. 1985. On rationalized H- and co-H-spaces with an appendix on decomposable H- and co-H-spaces. Manuscripta Mathematica, Vol. 51, Issue. 1-3, p. 63.

The brushes make contact with a device called the commutator located on the stator. The commutator reverses the current direction flowing to the rotor wires, flipping the electromagnetic field, and ...

Electric vehicles are obviously different from gas-powered cars, but do they have engines? We explore how EV motors and drivetrains work.

[Matthias] explains how to exclude harmonics, where to find power line hum, isolating commutator artifacts, and how to do all the calculations. You’ll need to know a little about your tooling to ...

Exploring how autoclavable brushless DC motors are powering advances in surgical power tools. 18/09/2024 Portescap S.A. The ...

In a dynamo, a split ring commutator changes the coil connections every half turn. As the induced potential difference is about to change direction, the connections are reversed. This means that ...

On either side of each synth is a commutator that contacts salvaged rotary tool brushes which provide power through the hexagonal brass supports. Each synth retains its own speaker and controls ...

The RC truck world has changed dramatically over the last few years. At one point, you needed to be ready to spend hundreds of dollars and seek out specialty shops to get true hobby-quality ...

The research indicates that the most effective way to cool a motor is through a combination of pumping oil through the motor shaft and using journals to carry oil to the outside of the rotor using ...

In this study, we investigated the neuronal activity of the dentate gyrus (DG) with electrophysiological and optical imaging tools during sleep-wake cycles. We found that the activity of major ...

Having originally been performed on Broadway back in 1948, Kiss Me, Kate first appeared in the West End in 1951 and has ...
