Q:my ac fan motor changes directions each time it stop and start?
All ac motors have the ability to spin in both directions. Its however the start windings that force it to go in one direction. To me is sounds like the capasitor is not working or the connections are dirty going to it.
Q:synchronous motor operation?
both of the two people above are correct in their formula, one uses 120f/no. of poles, the other uses (60)f/pole pairs which are equal, besides poles are always pair in either motor or generator windings.
Q:has anyone aput an ac drive on a slip ring induction motor after shortcircuiting the rotor terminals ?
Variable frequency drives VFDs) can be connected to slip ring induction motors with shorted rotor terminals. Because of ringing voltage transients that occur at the waveform switching transition points, VFDs cause voltage stresses on the motor insulation. Motors rated for VFD use are recommended, but older motors can be used. Output reactors or dv/dt filters are recommended for use with older motors. Most VFD suppliers can provide detailed recommendations. Many suppliers have experience with crane retrofits and can provide information and VFD features for coordinating the VFD operation with friction brake controls etc.
Q:I have a AC induction motor,i use a strong clamper to lock the motor shaft.Then i open the power supply.?
Any well designed motor will have a very low impedance with a locked rotor. Low impedance means high current and much power. Locking the rotor is never a very good idea. Try to understand the concept of back EMF.
Q:Structure of alternating current motor
AC motor consists of stator and rotor, and the stator and rotor is using the same power, so the current of stator and rotor in the direction of change is synchronous, i.e. the current direction in the coil is changed, and the direction of the current in the electromagnet, according to the left-hand rule by magnetic coil coil can continue to turn the direction. Go on.
Q:speed of a six pole a.c motor?
n=120f/p =120(50)/6 =1000 slip speed=0.06(1000) = 60 Actual speed= 1000-60 =940 rpm
Q:What happens to DC motors when they are connected to AC current?
Vibration at the frequency of the AC and higher current draw, meaning the voltage will have to be lower for the same amount of power and heat. That's because a spinning motor creatures back-voltage which reduces the current, a still or oscillating/vibrating motor does not. Most AC sources are higher voltage than DC rather than lower. If you connected a cordless drill motor to wall power you'd blow a fuse. And, if the fuse doesn't pop fast enough, you'd permanently fry the motor with a bang/pop and the smell of burnt plastic.
Q:How to build a generator with AC motor?
nicely you already figured it out that this would not paintings. i could propose to ignore the assumption with a capacitor start up electric powered motor. in case you're taking the motor aside then you certainly'll see that the armature or rotor consequently would not have a winding for use for excitation. that's the trick, with the intention to generate potential you may create a rotating magnetic field which may be regulated first, that's no longer the case right here. i could propose to apply an old vehicle alternator, then cost a battery with the potential popping out of this and use an inverter to get a good (in Voltage and Frequency) AC out of it.
Q:Electric Motors?
In a DC motor power is fed usually to the internal shaft with brushes, there are two or more magnets on oposite sides of the caseing. the power goes through a winding or coil that creates a magnetic field. pushing the coil away from one magnet and towards anouther with the opposit charge. As it spins the brush looses contact with a contact plate and then makes contact with anouther contact plate for a different winding, and the process happens again, as the shaft turns different windings are energised keeping the rotation going. In an AC motor works about the same however an AC motor makes use of the alternating direction of current to create and colapse magnetic fields that push then pull the rotor around. SO in answer, it works of magnetism, specifically electromagnets.
Q:How to make a motor spin faster without using more voltage?
If it is an AC motor, the speed will be set by the frequency divided by the mumber of pair of poles. One pair of poles will give you the highest speed, equal to the network frequency. Most AC motors are two pairs of poles. You can also use a variable frequency drive. If it is a DC motor, it will spin faster if you reduce the shunt field current/voltage. I.e., descreasing the strenght of the fixed side magnets . .
