In most everyday materials, such as copper, silver and silicon, the behavior of electrons is relatively predictable. In ...

Zero-torque and counterbalanced putters share some things in common, but buying the wrong one can be an expensive mistake ...

Shortened overall lifespan: A motor rated for 20–30 years may fail in just 3–5 years, all because of an electrical supply ...

Bengaluru startup Vimag Labs patented its fifth rare-earth-free EV motor as China's export controls push global automakers to ditch magnets.

In the Machinery subject of the Third-Class Chief Electrical Engineer Examination, the combination of "proportional displacement + T ∝ V²" is a definitive theme for Problem B regarding wound-rotor ...

A problem on finding generated torque. The basic principle is Torque = Output / Angular Velocity, and the key is to find the armature resistance that connects the two operating states using operation ...

The nice thing about automatic transmissions is that you don't have to think about shifting gears. They appear simple as anything from the driver's seat, but as anyone who knows how automatic ...

Abstract: Magnetic properties of electrical materials are of great significance to be accurately modeled and effectively incorporated in numerical analysis of electromagnetic fields. In this article, ...

Abstract: Flux-weakening control is usually used for permanent magnet synchronous machines (PMSMs) to operate above the rated speed, which will cause a high $d$ -axis ...
