What happens when voltage is applied to the stator?
Stator Voltage Control is a method used to control the speed of an Induction Motor. Hence, to reduce the speed for the same value of the same current, the value of the voltage is reduced and as a result, the torque developed by the motor is reduced. …
Does a stator rotate?
As the magnetic field of the stator rotates, due to the effect of the three-phase AC power supply, the induced magnetic field of the rotor is attracted and will follow the rotation. The rotor is connected to the motor shaft, so the shaft rotates and drives the connection load.
What are the drawbacks of stator voltage control method?
Disadvantages of this method is that the smooth speed control is not possible . This method is more costly and less efficient as two different stator winding are required. This method of speed control can only be applied for squirrel cage motor.
What are the disadvantages of stator voltage control method?
Due to change in firing angle ‘α’, the output voltage waveform is distorted and it will be rich in harmonics.
What happens when a stator goes bad in an engine?
While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up. Click to see full answer. Keeping this in view, what causes a stator to go bad?
What causes voltage imbalance in a stator motor?
Voltage imbalance has the same impact as that of the under voltage. If one of the winding gets partially damaged, its winding impedance will change and will try to create magnetic imbalance which in turn will create current imbalance. (To measure Undervoltage, Load and Current imbalance you can use MachineSense PA.
When do you need to replace a stator on a motorcycle?
Generally speaking, you don’t need to replace a stator if your motorcycle or motorsport machine is still running smoothly. Stators have unpredictable lifespans, and the timing of replacements isn’t always dependent on the stator’s age, so there’s no reason to replace one that may very well run for several thousand more miles if left untouched.
What happens if you short circuit a stator winding?
Current waveform gets distorted and more importantly peak can even go beyond fundamental peak which unneccessairily increases heating of the coil. In the long run, insulation can get damaged and inter-turn ( a portion of the winding) can be short circuited/burnt.
What to do if your stator on your ATV is bad?
This is a free and easy fix so try it out if your battery is still good. Voltage regulator rectifier unit: If your voltage regulator is bad, you’ll have the same problems as if your stator is bad. This can make it difficult to determine, which is the problem. You can test this with a multimeter to see if it is working.
What happens when a stator dies on an engine?
While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up. This needs to be a fairly heavy duty coil. I previously tried using two universal coils intended for small engines.
What should I do if my Honda stator is weak?
Note that as written this system will bypass the CDI portion of your ignition system (if present) and replace it with a more traditional one. I devised this system when the stator on my Honda XR-100 got so weak that it couldn’t power the spark plug, preventing the engine from running.
