What is a pole on a stator?
The motor drive energizes stator teeth one after the other to make the rotor turn, thanks to its magnets’ tendency to force alignment with the stator teeth. Simply defined, a pole is a north or south magnetic field of force that is generated by a permanent magnet or current passing through a coil of wire.
How do you find stator poles?
The actual running speed is the synchronous speed minus the slip speed. To determine the number of poles, you can read the data plate directly or calculate it from the RPM stated on the data plate or you can count the coils and divide by 3 (poles per phase) or by 6 (pairs of poles per phase).
What is the purpose of the stator?
In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
Where is the stator mounted?
The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electro-magnets arranged around a cylinder, with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor’s shaft.
Which is better 2 pole or 4 pole motor?
A 2 pole motor has high speed due to less number of poles. Conversely, a 4 pole motor has low speed due to more number of poles. A 2 pole motor is more efficient on the flip side, a 4 poles motor is less efficient. A 2 pole motor has more RPM value; on the other side, the 4 poles motor has fewer revolutions per minute.
How can you tell if your engine stator is bad?
You can tell the stator is bad, based on the symptoms of the engine. Though it won’t be a clear and cut situation. You will need to test the stator and we’ll cover that in a second. You can know you have a bad stator by looking at it. If the stator is covered in salt and corrosion.
How does the stator work on an engine?
The stator is made up of windings that produce alternating current electricity. As the magnets on the flywheel spin around the windings when the engine is running. This AC electricity is used by the engine to run all of the ignition components of the engine.
What are the different types of stators on an ATV?
There are three different types of stators: Single Phase Stators: Not as powerful. Uses a single wire to create the coils that circle the iron core. You will see two wires in the cable coming off the stator.
How do you test the resistance of a stator?
First perform the static stator tests. With the ignition switch in the “Off” position, disconnect the regulator from the stator. Set the multimeter to “Resistance” or “Ohms” on the lowest scale, and insert one probe into one of the stator pin sockets.
How is a stator attached to an engine?
First the easy: attaching the negative (black) wire going to the engine. This wire can be attached to any conductive part of the engine assembly. On cars and motorcycles the metal parts of the engine are in electrical contact with each other, which causes them to make up one large electric terminal.
How can I tell if my stator needs to be replaced?
This test makes sure that the stator isn’t shorting out to the ground. Your meter should read “OL” or open line. If the multimeter is picking up a reading, it means your stator needs to be replaced. Repeat this test for each of the windings.
How much does it cost to get a new stator?
Create a Battery-op Ignition System for Less Than $50 The cost of a new stator can be hundreds of dollars. Without a good stator, your engine will run poorly or not at all. This solution completely bypasses the stator by using a 12 volt battery to power the ignition system.
Is there a way to bypass the stator?
This solution completely bypasses the stator by using a 12 volt battery to power the ignition system. Everything required can be purchased for under $50. It will work on all contact breaker point engines (old style), and some electronic controlled ignition (newer style) ones. The guide is for contact breaker systems.
