How does a three phase motor work

WebJan 25, 2024 · Used in three-phase motors. The resistance in the sensor remains relatively low and constant over a wide temperature band and increases abruptly at a pre-determined temperature or trip point. When this occurs, the sensor acts as a solid-state thermal switch and de-energizes a pilot relay. Three-phase motors operate by the principle of electromagnetic induction which was discovered by the English physicist Michael Faraday back in 1830. Faraday noticed that when a conductor such as a coil or loop of wire, is placed in a changing magnetic field, there is an induced electromotive force or EMF that is … See more To understand three-phase motors, it is useful to first understand three-phase power.
