Fundamentals of Electric Motors

Follows "Left Hand Rule". Rotating stator flux (B) sweeps through air gap. The rotating magnetic field from the stator "cuts" through the rotor bars and induces current in them. The current flows through the bars to one of the end rings, through the bar on the opposite side of the rotor then returns through the other end ring etc.

EJ Moyer, U. Chicago April 29, 2010

Electric motors are estimated to now consume over 25% U.S. electricity use (though some estimates are even higher, to up to 50%, and over 20% of U.S. total primary energy). While large electric motors can be extremely e cient at converting electrical energy to

Electric motor

A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. The stator is similar to that of an induction machine consisting of a cylindrical iron frame with windings, usually three-phase, located in slots around the inner periphery. The difference is in the rotor, which normally ...

AC Motor Theory

In an AC induction motor, a magnetic field is induced in the rotor opposite in polarity of the magnetic field in the stator. Therefore, as the magnetic field rotates in the stator, the rotor also rotates to maintain its alignment with the stator''s magnetic field. Figure 1 : Three-Phase Stator. From one instant to the next, the magnetic fields ...

For clear understanding the principle of DC motor we have to determine the magnitude of the force, by considering the diagram below. We know that when an infinitely small charge dq is made to flow at a velocity ''v'' under the influence of an electric field E, and a magnetic field B, then the Lorentz Force dF experienced by the charge is …

How Electric Motors Work | HowStuffWorks

HowStuffWorks. The key to an electric motor is to go one step further so that, at the moment that this half turn of motion completes, the field of the electromagnet flips. You flip the magnetic field by changing the direction of the electrons flowing in the wire, which means flipping the battery over.

Electric Motor

Let''s look at the working of an Electric Motor. When battery is switched on, current flows through coil AB from A to B, and Magnetic Field is from North to South... So, by Fleming''s left hand rule, downward force is applied on AB. Similarly, upward force is applied on CD. Thus, the coil rotates with AB moving down and CD moving up.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor''s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor''s shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy.
