The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding. As a result, the … Se mer An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, … Se mer Polyphase synchronous motor If connections to the rotor coils of a three-phase motor are taken out on slip-rings and fed a separate field current to create a continuous magnetic field (or if the rotor consists of a permanent magnet), the result is called a Se mer • Silvanus Phillips Thompson: Polyphase electric currents and alternate current motors • Univ.Prof. Dr.Ing. Martin Doppelbauer: The invention of the electric motor, Karlsruhe Institute of Technology – KIT Se mer Alternating current technology was rooted in Michael Faraday's and Joseph Henry's 1830–31 discovery that a changing magnetic field can … Se mer Slip If the rotor of a squirrel cage motor were to run at the true synchronous speed, the flux in the rotor at any given place on the rotor would not change, … Se mer Universal motor and series wound motor A universal motor is a design that can operate on either AC or DC power. In universal motors the stator and rotor of a brushed DC motor are both wound and supplied from an external source, with the torque being a … Se mer NettetMotors that cannot be independently measured, such as pump motors with wet rotors.
