An electric motor is an electrical machine that converts electrical energy into mechanical energymost electric motors operate through the interaction between the motors magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft. How to control 3 phase induction motors.
It is also used to power large motors and other heavy loads. The main principal of driving such a motor is a particular sequence of commutation of the stator windings that creates several points in which the windings attract magnetically opposite poles of the rotor with maximum force. Secrets behind the rotation.
This surge current reduces as the motor accelerates up to its running speed. Working of three phase induction motor production of rotating magnetic field. Three phase motor power control wiring diagrams 3 phase motor power control wiring diagrams three phase motor connection schematic power and control.
Three phase electric power is a common method of alternating current electric power generation transmission and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. When the stator windings of an induction motor are connected directly to its 3 phase supply a very large current 5 7 times full load current flows initially.
It has been estimated that 70 to 80 of all electricity in the world is consumed by these motors. A three wire three phase circuit is usually more economical than an equivalent two wire. Electric motors can be powered by direct current dc sources such as from batteries motor vehicles or rectifiers.
With three driver inputs it is possible to create only two levels at the ends of the windings. The stator of the motor consists of overlapping winding offset by an electrical angle of 120 owhen we connect the primary winding or the stator to a 3 phase ac source it establishes rotating magnetic field which rotates at the synchronous speed.
