AC Motor Speed Controller | Motor Speed Control | Motor

An electronic speed variator (in English, variable frequency drive or VFD) is a device intended to regulate the speed and the torque of an AC electric motor by varying the frequency respectively the current, delivered at the output thereof. this.

Their applications range from smaller to larger motors, such as those used by drills. While about a quarter of the world's electricity consumption comes from electric motors used by industry, variable speed drives are still not widely used, while they allow significant reductions in energy consumption.

Advances in power electronics have reduced the cost and size of variable speed drives over the past four decades. They concerned both the semiconductor switches used, the topology, the methods used in control and simulation, as well as the hardware and software used for the control.

Variable speed drives can be either low voltage or medium voltage. Some operate as inverters, others as rectifier / inverter.
