A capacitor is connected in the machine's starting winding. This places the starting-winding current out of phase with the current through the main winding, and results in a rotating magnetic field, providing the torque necessary for the machine to start.
No, caps are rated for different tasks like starting motors and for different motors. Just look at it this way, a capacitor is a battery and a AA battery will unlikly start your car!
no, it will burn out, sir i am sorry for you but my 1.5 HP 220 volts water pump has a 125 volts starting capacitor since new and still work for the past 3 years.
Most refrigerators use a single-phase induction motor which needs a capacitor to make it start running in the right direction.
no
Definitely.
Do you have a dual capacitor that starts both the compressor and the fan motor? You need 230V to power the compressor. You should have one wire from the capacitor going from the start terminal on the compressor and one going from the common terminal to common on the capacitor.
Yes. Or the motor has just burnt out! If there is no burnt smell from the motor's windings and you know the power supply to the fan is good, it is worth replacing the capacitor with an identical one. NOTE: It must not be a polarised electrolytic type, it must be non-polarised and rated at the peak mains supply voltage or higher. Such capacitors are usually sold as "AC Motor Start" or "AC Motor Run" capacitors. For a 120 Volts motor use a capacitor rated to operate at 170 Volts peak. Usually these are manufactured to handle at least 200 Volts Peak AC . For a 240 Volts motor use a capacitor rated to operate at 340 Volts peak. Usually these are manufactured to handle at least 400 Volts Peak AC. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
In Europe 240 volts is standard, so no a 115 volt motor will not work. In USA 120 volts is standard, so if your sub-panel has 120 volts, (check with voltage meter) then yes. Read carefully, To get 240 volts in a sub-panel in USA the electric company brings two (2) wires, each wire has 120 volts, 120 + 120 = 240. One of those 120 volts will run your motor. Look for the wires from the electric company and check them with your voltage meter. If this is a commercial application you will need to call an electrical contractor, power companies for commercial applications do not follow the above.
No, you will need a commercial mixer for that.
Yes, if you try to continuously run the motor at 120 volts. It may run, but at a slower speed. The slower speed will not provide enough cooling for the windings, and thus it will eventually be destroyed. No, if you incorrectly wired it at 120 volts, and then rewired it correctly, for the HIGHER 240 volts. Keep in mind that there are many different types of motors out there and this answer only applies to this specific application.
The voltage of 120 volts is more common that the lower voltage of 12 volts.

A circuit board is the inducer motor. It runs off of 120 volts.
A starting cap is placed in circuit of the start windings only when the motor is starting and is normally of a higher capacitance than a running cap, in the region of 70 - 120 mf, where a running cap stay connected with the start windings of the motor and is normally an 8 mf cap.

SPL means the motor is Split-Phase, on the motor where you found that it should have two numbers, i.e. 120/240 SPL HP. Meaning the motor operates different given 120 volts compared with 240 volts.

12/2 with ground.
Volts * Amps = Watts 120 Volts * 12.5 Amps = 1500 Watts Doesn't sound like a good idea.
50% of 120 volts = 50% * 120 = 0.5 * 120 = 60 volts
It is possible to check the resistance of the motor leads compared to a known motor. You can also connect the leads to 120 volts temporarily. If the motor hums and runs slowly or not at all it is a 220 volt motor. If it runs normally, then it is a 120 volt motor. Testing should be done for only a few seconds so if the motor is designed to be run on 220 volts, you don't overheat or damage it on 120 volts.AnswerRead the nameplate information.
No, you will need a commercial mixer for that.
