What is the difference between a field winding and an armature winding in any machine?
simply saying u that field winding is a winding present at the stator of the motor and is used to produce the magnetic field and the armature winding is the winding present in the rotor and is used to rotate the shaft of the motor. there are some machines with permanent magnets, those permanent magnets are used as the major source of magnetic flux in the machine instead of the field winding .
Will a single-phase Induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
What are stationary part of dc motor?
The stationary part of any motor or generator is termed the 'stator', and the rotating part is termed the 'rotor'.The stator comprises the main frame (chassis), the magnetic circuit, and field windings.
Causes of over temperature of induction motor?
the main reason is the amount of current flowing in the motor's winding is huge (over current) that why temperature begins to build up, continues using may end up to a burned motor. over voltage, defective bearing / bushing, shaft misalignment, defective insulation are some of the reason why motor experience over current.
Why a single phase induction motor is not self starting?
Single phase induction motor is not self starting because, when the main winding is excited from a single phase supply, it produces an alternating magnetic field instead of rotating magnetic field in two phase and 3 phase induction motor. According to double field revolving theory any alternating vector can be resolved into two vectors rotating in opposite directions, each having magnitude equal to one half the magnitude of the actual vector. The vectors will be rotating in such a way that their resultant will be zero at every instant. Thus a single phase induction motor fails to produce a net starting torque, and is not self starting.It can be made self starting by any of the methods below1) By using an aux winding in series with a very high resistance2) using two capacitors,in series with the aux wdg,one with intermittent duty and the other one with continuous duty3) Using shaded poles
Where are 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 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.
What the main different between shunt motor and induction motor and AC motors?
induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
How do you counter the induced voltage spark during the generator?
By creating a rotating electric field. The generator has two main sets of windings - the field windings (the spinning ones on the rotor usually) and the stator windings(the stationary part connected to the grid). The field windings are electrified to create an electromagnet out of the rotor. Spinning the rotor creates a rotating electric field, which induces a voltage on the stator windings.
Differences of induction motors and synchronous motors?
An induction motor is a type of electric motor. It uses alternating current (AC) electricity and induces (hence the name) a current in the rotating part to make it move. You might call it a rotating transformer. A hydraulic motor is powered by a fluid. Typically this might be an oil, The oil forces round some gears or vanes to make the motor shaft turn. A hydraulic motor requires an external supply of pressurised fluid, e.g. oil. Large earthmoving equipment or diggers use hydraulic power as it is compact and powerful for its size.
Can an older pool pump draw more amps to trip main breaker?
Yes, an older pump/motor can draw more amps. This usually happens when the motors windings are going bad or the bearings are going out. This causes the motor to have to work harder to rotate. It should have its own breaker. If its blowing your main, The motors windings are probably bad and the motor should be replaced.
Does a induction motor need excitation?
The induction motor is the special kind of motor which runs below and above the synchronous speed. which the synchronous motor runs nearly equal the synchronous speed. The operation of synchronous motor runs with dc field excited hence separate dc field current is given to the field circuit. where as the induction motor the field and main field is drawn from the same supply hence no excitation is required. But due to this separate starting mechanism has to be required in case of the single phase induction motor.
Will a induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
Principle and working of single phase induction motor?
Will the principle operation is very complex and would require a fair amount of reading in a text book. But the simple operation of a split phase motor is when a single phase motor has two windings. The main operating winding a and auxiliary winding used to create a rotating magnetic field. The main winding is large wire with lots of turns so under locked rotor conditions it is seen as a large inductive reactance and the aux. winding the smaller wire with fewer turns so it is seen a mainly resistive. This 90 degree phase shift is used to produce more starting torque. If a resistive split phase motor aux. winding is switched out shortly after starting. The aux. winding can also be phase shifted by using a capacitor installed in series with it. This is in the case of capacitor start and capacitor run motors.
