How does a permanent-split capacitor motor work?
This is a piece of machinery similar to a capacitor-start motor and operates on an LC circuit. One of the main differences, however between the two is that there is no centrifugal switch and instead of being initiated by an inital start winding montion, the permanent-split capacity motor is permanantly connected to the power source.
Why 3 phase induction motor is self starting but synchronous motor is not?
the induction motor as soon as you turn on the power the rotating magnetic field is set up. the shorted winding in the squirrel cage see this and builds up a temporary magnet when its up to synchronous speed there is no longer current in the shorted winding in a single pole motor 60hz this speed is 3600 rpm depending on coupling and skew induction motor is always less than synchronous speed. the synchronous motor as soon as you turn on the power the rotating magnetic field is set up the permanent magnet 0 to 3600 rpm in 1/60th of a second this requires all the power you can deliver until you reach synchronous speed a bit hard on the power source smaller synchronous motors sometimes have a squirrel cage and permanent magnets and enough impedance so they dont put a heavy load on the power electric clocks have the shorted windings on the poles self starting hi impedance some older electric clocks didnt have the shorted windings and need to be nudged to get then spinning
Can you change the generator into motor?
Yes. Certain types of motor. The best for this are DC motors with a permanent magnet field. DC motors with a field windings, need an excitation voltage to produce power. Simply rotate the motor, with an external force and DC current comes out of where you normally put power in. AC motors, induction motors, (squirrel cage type, typically used for domestic fans) are no good.
Can a Ac electric motor be converted into a generator?
I found a web site that explains how to do it: (1st link) It seems to make sense, but I have not tried it yet. That is for single phase induction motor here is for three phase motor (2nd link) I tested both links and it works perfectly.
What do you need to build your own dynamo?
Physics is reversible. SO you can use the inverse properties of any DC motor. Which means that when you give electricity, the motor rotates. But if you rotate the motor, with some extra circuit, It can act like a dynamo.
How you do Speed control of permanent magnet synchronous motor?
To vary the speed of a permanent magnet synchronous motor, you need to vary the frequency of the AC power source. Of course, this also means you need to vary the voltage because the power factor is going to change, and you need to compensate for that or you might damage the motor.
Is a north or south magnet in a compass a permagnet or an electromagnet?

Is there any successful magnetic motor?
Yes, they are permanent magnet DC motors. They run on DC and have been here for decades. The idea of a motor powered by magnets has been also with us for generations now. These are called perpetual motion devices. Motors will always need energy to run. They can not derive their energy from a magnet unless it consumes that magnet.
Can a permanent magnet solenoid be modified to work like a permanent magnet linear generator?
yes - need to run electricity through it to make it a linear magnetic generator.
When would you want to use an electromagnet rather than a permanent magnet?
When you need a magnet you can turn on and off an electromagnet is used.
Why do you need a magnet for a homemade electric motor?
ya dont
Does a vacuum cleaner need a magnet to work?
Some kind of magnet or magnetic field is necessary for a motor to operate. Alternating current vacuum cleaners (that plug into the wall) have motors with electromagnets. Direct current vacuum cleaners (that plug into the car's cigarette lighter socket) have motors with permanent magnets.
Where from permanent magnet get energy?
Permanent magnets don't get energy from anywhere. The nature of the atoms a natural magnet is made of allow for the free exchange of electrons with other objects that also have free electrons. Energy is conserved in the system, not used and so a natural magnet doesn't need power to operate.
A magnet made from a steel paperclip is most likely an?
A magnet made from a steel paperclip is most likely a(n) temporary magnet.
Which TWO types of magnets do you need to make a simple motor?
The most basic of electric motors consists of a permanent magnet and an electromagnet. This is not a requirement for all types of electric motors and most modern electric motors do not have permanent magnets. The stator and rotor are the two active elements of a simple electric motor and both have magnetic fields in the various types and designs of simple motors.
Atv Motor seized what do you need to replace?
No way of just knowing until you disassemble it and carefully inspect EVERYTHING. Good luck.
Do a Vacuum cleaner needs a magnet?
If the vacuum cleaner is powered by electricity this is used to turn the electric motor which is needed to create the suction or vacuum. That motor either has permanent magnets inside it, or the current passes through many "turns" of wire to create magnets when you switch the cleaner on. Early experiment in electricity showed that if a wire is moved in a magnetic field some current is created. Similarly, if a magnet is moved near to a wire the same result occurs. So, yes the cleaner does need a magnet.
