Electric motors can seem very mysterious! How do they use electricity to start rotating? Let's break it down step by step to ...

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 ...

[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 ...

With the recession in Germany spreading to the automotive supply chain, and the difficulty of making the transition to a ...

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 ...

Kevin Brannigan, Marketing Manager at Makita, outlines the benefits of cordless tools for hard landscaping work and highlights some of the products that professionals should consider.  The conventiona ...

One of the first big improvements of this build style is the shift from the originally used spark gap commutator to that of a direct AC drive via a MOSFET oscillator. This improves the primary ...

This causes the motor to begin to rotate. After half a turn, the split ring commutator reverses the direction of the current through the coil so that the motor continues to rotate. Answering tip ...

It used direct current and had the same basic components that are still in use today: a stator, a rotor and a commutator. Jedlik put his electric motor on a small wheeled board in 1828 ...
