Induction motor - Wikipedia

The power factor of induction motors varies with load, typically from around 0.85 or 0.90 at full load to as low as about 0.20 at no-load, due to stator and rotor leakage and magnetizing reactances. Power factor can be improved by connecting capacitors either on an individual motor basis or, by preference, on a common bus covering several motors. For economic and other considerations, power ...

Squirrel Cage Induction Motor - an overview ...

The induction motor speed decreases by a few percent when the motor goes from no load to full-load operation. The full-load speed is a function of the motor design and power and is usually in the range of 94–99% of the synchronous speed; the difference is the “slip.” Figure 2 shows the typical construction of a squirrel-cage induction ...

speed caged induction motors which use conventional alternating electric current (AC) to induce a force (torque) on their rotor, causing it to rotate. The diagram below shows the components of a fixed speed caged induction motor. As electrical power is applied to the motor, a rotating magnetic field is created around the stator (1). This induces currents and associated magnetic fields in the ...

What Is an Inductive Load? (with pictures)

01/02/2021  David Sandoval Date: February 01, 2021 An electric motor is one type of inductive load.. An inductive load is a part of an electrical circuit that uses magnetic energy to produce work. Most electrical appliances, motors, and other devices can be classified as either inductive or reductive, and this usually has to do with how they absorb and process energy.

All About Induction Motors - What They Are and How They Work

18/03/2021  In induction motors, the stator’s rotating EMF induces an opposing EMF in the rotor wires, causing it to spin (via Faraday’s Law Lenz’s Law). Induction motors are often called “asynchronous” motors because their rotational frequency is always lower than the AC frequency.

Effect of Voltage Variation on Induction Motor ...

Some motors are name plated 208-230 / 460V, indicating that the motor is "suitable for use" at 208 volts. Extreme care should be exercised if using this motor at 208V. 230V is the "rated" voltage, and 208V falls within the minus 10% range. So theoretically, the motor will work at 208V. This logic has some danger. The motor will draw higher amps, run hotter, and have lower efficiency. It should ...

Voltage controller - Wikipedia

The overall power is reduced by any inductive component of the resistive load. The load has to be of increasing torque in nature: Voltage controllers can alter the speed of a motor by altering the incoming voltage, but the motor must have an increasing torque load (e.g. Industrial fans, winding machines).
