Webb12 sep. 2024 · It depends on the shapes and relative positions of the two coils, and it is independent of the currents in the coils. The SI unit for mutual inductance M is called the henry (H) in honor of Joseph Henry (1799–1878), an American scientist who discovered induced emf independently of Faraday. Thus, we have 1 H = 1 V ⋅ s / A. Webb8 apr. 2024 · Induction motor-Induction motor is the type of AC motor which runs on non-synchronous speed; that is why it is also called asynchronous motor. This motor applies … WebbTorque is produced in an induction motor through the interaction of two magnetic fields. The first rotating magnetic field is created by currents flowing in the stator windings. This rotating field cuts the conductors in the rotor and induces a voltage in them. lodge alley inn charleston
