Why do we need to keep more turns in running winding?
If you twist motor shaft with fingers it will run in whichever direction you twist. To self start a single phase motor one must create a rotating magnetic field on the stator. Two windings are used and the difference in impedance creates a phase delay in the magnetic fields produced by each winding allowing the motor to start.
What causes an electric motor to stop running?
The motor’s design may be capacitor start, or capacitor run. These types of motors are what you will find in most home and workshop applications. Special purpose industrial motors (DC, three phase) will have some differences and I still know nothing about them. The most common cause of HVAC failure during the hot summer is a motor capacitor.
Is it possible to make an electric motor run again?
There will always be a little drag, but the shaft should spin relatively freely. Still, an older motor may have bearings with dried grease. If the bearings are not rusted inside, you can probably work new grease into them. and improve them greatly.
Can a Ford F-150 start and run?
Truck will start and run as long as you want, but does have hesitation when hitting gas. Sounds fine when pressing on gas peddle gently though. Turn off truck, try to restart, engine just cranks. Try to start with gas peddle to floor, engine starts up very poorly (sputtering). I keep holding gas and the sputtering finally clears up.
Why does my Car start but won’t start?
If it cranks but does not start, sometimes a temperature sensor is bad and the computer can’t figure out the proper amount of fuel to inject. Just a little off and the engine won’t start. After a half hour, the engine just happens to get to a good starting temperature.
Why does my car run when the ignition is turned off?
With the ignition turned off and the car continuing to run, simply remove the plug from the alternator (DO NOT TRY AND REMOVE THE BATTERY POWER WIRE FROM THE POWER STUD!) and the car should shut off if the alternator is creating the problem. If it does not stop running, your feedback problem is coming from something other that the alternator.
What to do when your car does not stop running?
If it does not stop running, your feedback problem is coming from something other that the alternator. If you are using an aftermarket ignition unit, check to see if there is a fix available that includes a diode to put in line on the ignition feed to keep their system from back feeding into the ignition switch.
Why does my alternator run when I Turn Off the car?
Generally, an OEM harness will not have the problem of alternator “run-on”, as there is usually a resistance wire in the dash harness to keep this from happening. Solution: To figure out where the problem exists, start the car and with the key in the ON position and the car running, turn off the key.
