How do electromagnets work in motors
WebDec 13, 2024 · Electromagnets use magnetism to transfer energy from one to the other. The motor is powered by direct current and runs on an alternating current generated by an electronic card that converts the direct current into three-phase variable frequency. WebThe electric and magnetic force are really two faces of one phenomenon - electromagnetism. Electromagnetism is responsible for the phenomena of electricity, magnetism and electromagnetic radiation. On one hand, moving charges produce a magnetic field. On the other hand, an electric current can be produced in a circuit by a …
