The first locomotive to successfully use an AC (alternating current) three-phase asynchronous traction motor drive system was the German DE2500 diesel-electric in 1971, built by Henschel-BBC. DB ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it’s ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

BEN Buchele introduced a robust, low-maintenance three-phase asynchronous motor whose stable grey cast iron design is touted to withstand the harshest environmental conditions: salt water, salty air ...
