The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

Lock up your flywheels, folks, an American inventor is coming after them. Randy Moore of RK Transportation is working on an idea that replaces an engine's flywheel with a lightweight rotor with ...

• Electromagnetic clutches and brakes are electrically activated but transmit torque mechanically. • Engagement time depends on magnetic field strength, air gap, and inertia. • Burnishing increases ...

In 1831, Michael Faraday discovered that subjecting a coil to a moving magnetic field induces a current. Today, electromagnetic induction powers most electric motors, along with a phenomenon described ...

I recently ran into an interesting dilemma while running tests on TI’s new InstaSPIN™-FOC sensorless motor control software. “How do you define motor torque?” On the surface, this sounds like an easy ...

Horton Inc. has introduced the new higher-torque EC600 electromagnetic on/off fan drive designed for use on medium-duty trucks, buses and off-highway equipment. In today’s cost-conscious market, ...
