Definition of a resistance-start induction run motor?
Resistance start-induction run motors are commonly known as split phase. They are only single phase motors. They have 2 sets of windings, the Start winding which is high resistance and low inductance made for thin wire, and the Run winding which is low resistance and high inductance made for thick wire. The 2 windings are set skewed about 30 degrees on a twist. This is to create the angular rotary motion, which is what a motor is all about. On start up both start and run windings are energised. Some form of switch disconnects the start winding when the motor is about 75% up to speed, and only the run winding remains in the circuit. There you have it.....
The part of an ac induction motor that turns is called?
The part of an AC induction motor that turns is called the rotor. The rotor is located inside the stator, which is the stationary part of the motor. When alternating current flows through the stator windings, it creates a rotating magnetic field that induces current in the rotor, causing it to spin and produce mechanical output.
What are motor made from?
an electric motor is a copper winding or 3 separate windings depending on the phase, the copper winding is the centralised inside of a iron magnet, this is also how a generator is made instead of putting a current on you turn the windings to receive a voltage .
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
What is a split phase motor?
Well the big identifier of a split phase induction motor is the main and aux. winding. The rotor, stator, case, etc. These two windings is what sets it apart from other motors. These windings are phase shifted to produce a rotating magnetic field for starting to allow the motor to have better starting torque.
Induction Motor working principle?
An induction motor works on the principle of electromagnetic induction. When an alternating current flows through the stator windings, it creates a rotating magnetic field. This magnetic field induces a current in the rotor windings, causing it to rotate and drive the attached load.
How do you get the number of turns of the primary windings of the induction motor?
made on a machine that counts the loops of the wire as they are formed into usable coils, once coils are completed they are installed into the stator slots.
Reverse direction of singlr phase ac induction motor?
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
What will happen if you run induction motor beyond its rated speed?
The windings will heat up and evntually be destroyed due to the high rate of speed which induces more ccurrent in the windings
Why transformer does not rotate like induction motor Inspite both having same principle?
because transformer has primary and secondary windings only but in motor has stator has two windings and rotorAnswerIt could be something to do with the part that there are no moving parts!
Why dc motor is not named as conduction motor?
In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a Conduction motor. However, in ac motors, the rotor does not receive any electric power by conduction but by induction in exactly the same way as the secondary of a two winding transformer receives its power from the primary. That is why such motors are called as Induction motors. An induction motor can be treated as a rotating transformer i.e., one in which primary winding is stationary but secondary is free to rotate.
Where are the main windings of an AC induction motor situated?
Front and rear.AnswerThey are located in longitudinal slots that are machined into the inner surface of the stator.

What happens if the rotor in an induction machine is replaced with an iron cylinder?
Nothing. The motor won't run because you would no longer have the counter-acting magnetic field from the induction windings in the rotor.
What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
What is the minimum windings an induction machines has?
Two.
How Synchronous motor work with principal?
A synchronous motor comprises of a stator windings and a rotor with a squirrel cage and inside that is windings(coils). At starting, this motor is an induction motor running with slip. After the rotor has reached a certain speed, a DC current is applied to the windings inside the squirrel cage. A fixed field is induced in these windings. This field locks in with the synchronous rotating magnetic flux of the stator windings. The rotating stator windings then pull the rotor along. The amount of excitation current can be used to control the power factor of the motor, making this a popular type of motor for high power use with a constant mechanical load.
