For conventional flow (plus to minus) FLH rule is for motor action, and FRH rule is for generator action. So you can use FRH rule to determine the direction in which voltages are induced into the rotor by the rotating magnetic field, then use FLH rule to determine the direction in which the resulting forces, due to the rotor-bar currents, will act to rotate the rotor.

What is the main purpose of a single phase capacitor start induction ac motor?

A single-phase induction motor can run either way depending on how it's started because the stator field does not rotate. The starting winding, fed by a capacitor to produce a phase-advanced current, generates a small rotating field to start the motor going in the right direction. Once the motor has run up to speed it latches on to the main stator field, which can be resolved into two oppositely-rotating fields. The armature produces torque from only one of the rotating components.


Can you run a 230v 60HZ motor on 230v 50HZ power?

You may or you may not. It all depends on the task you are using the motor. If speed is not a concern for you then you may, but for sensitive systems where changes in motor speed affects the system then you may not. The reason is that the frequency of the power supply affects the motor speed. Frequency is directly proportional to speed.


What is induction heating?

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.induction heater including high frequency induction heating machine and middle frequencey heating machine. Induction heating applications for an induction furnace include induction welding, induction brazing, induction hardening, induction melting, quenching, forging, soldening, induction annealing and other forms of heat treatment. Induction heating is often used to heat graphite crucibles (containing other materials) and is used extensively in the semiconductor industry for the heating of silicon and other semiconductors. Induction heating can produce high power densities which allow short interaction times to reach the required temperature. That translates into lots of energy transferred into a material right now, with a very rapid rise in temperature.


What is the working principle of ac motor?

AC commutator motors, like comparable DC motors, have higher starting torque and higher speed than AC induction motors. The series motor operates well above the synchronous speed of a conventional AC motor. AC commutator motors may be either single-phase or poly-phase. The single-phase AC version suffers a double line frequency torque pulsation, not present in poly-phase motor. Since a commutator motor can operate at much higher speed than an induction motor, it can output more power than a similar size induction motor. However commutator motors are not as maintenance free as induction motors, due to brush and commutator wear.


How are the windings of a star delta motor tested?

In a 3 phase induction motor there is 6 wires frm the windings.Inwhich ,we can measure ohms value between each other.there are 2 different ohms value between each pair of three wires. lets say,10 ohm and 30 ohm.low voltage and high voltage side.can anyone say is it right to find the wingings of star and delta side?

How does electromagnetic induction works?

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. Basically it works because of electricity.

What is difference between d.c genrator and motor?

GENERATOR:converts mechanical energy to electrical energy.It works on flemings right hand rule.It works on the princple that an EMF is induced when a changing magnetic field links with the conductor. This emf is directly proportional to the rate of change of magnetic field linking the conductor.MOTOR:converts electrical energy to mechanical energy.works on flemings left hand rule.It works on the princple that a mechanical force is experienced by the current carrying conductor when placed in magnetic field.

What is the principle of motor action?

Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".
