Q: This american device is labeled as '60hz' but it runs on a universal brush motor, which means that it will still run fine in a '50hz' country without any frequency cycle disturbance, providing i convert the volts, right?I was told that bacause it's labeled on one stores website as '120V AC 60 Hz only' that it probably isnt a true universal motor.But I noticed You can get replacement Carbon Brush and Brush Spring Assemblies - This would futher indicate thats it's a 'true ' universal motor right?: A 60 Hz motor will operate on a 50 Hz supply, but not at rated speed and capacity. A 50 Hz motor will operate on a 60 Hz supply, but the rpm will be higher than specified. What are you operating and what is it worth to you to stay within specifications?

Q: Why would the fan motor on my ac unit stop working and will replacing it solve my problem: You didn't say what kind of car you have but you could have a bad resistor in the fan circuit. An easy fix.

Q: I have a 220v motor stripped from a hair dryer that looks like a DC. How can I differentiate (visually or through tests) a DC motor from a AC / DC (universal) motor?: It could be a universal motor or a DC motor. I have seen some 240V hair driers with a permanent magnet DC motor and a single half wave rectifier diode. Some tests: If there is a rectifier diode in series with the motor it is almost certainly DC only (keeping in mind it could only be used to reduce the average voltage by 50%). If it has permanent magnets for the field it is DC only. There would be a rectifier somewhere. If it has a laminated core for the field winding that is universal meaning AC/DC. It has to be able to reverse the field and the armature at the AC rate. Generally the armature (rotating part) will look similar for all types.

Q: I have it all disconnected and out of the unit. I am having trouble getting the blades off of the rusted shaft. (two rusted set screws) Any tricks out there on how to loosen them without damage to set screws? Any other advice would also be helpful...first time at this.: You might need a blower wheel motor puller, it's similar to a gear puller. Just don't hit the end of the motor shaft or it will mushroom it. Soak it in oil to loosen it. You know what the best thing for that is? break fluid for cars. It will loosen anything but don't get it on paint, it will strip paint off.

Q: wat vil happen if ac supply is given to dc shunt motor?: At first think how a D.C. motor works. When the coil inside the magnetic field rotates you get the mechanical energy from electric energy. In the case of DC motor the rotation in one direction is kept continuous by slip ring and brush so that we get mechanical energy continuously. But if you pass ac current through the DC motor, as a result of changing direction of current the rotation of the coil will change with respect to time. So the coil will not rotate totally rather it will vibrate. Frequency of the vibration will be equal to the frequency of the AC current. So the motor will not run in the way it generally runs. Shunt wound DC motors are not suitable for AC operation because the difference in inductance between the armature and the field causes a relative phase shift between the armature current and the field current. For a DC motor to operate with AC current, the armature and field currents must reverse at exactly the same time, as they do when the windings are connected in series. For reasonably good performance, the cores need to be laminated and the brush position needs to be set to 90°.

Q: Every dryer motor iv ever disassembled has one...I just inherited an old radiator hot water pump motor and it has one...These are the only true AC motors i ever encounter.: there are two windings (stator) in these types of motors. one is the starting windings and the other is the run windings. the switch in question is for the starting windings. start windings provide higher torque for the motor to start and as the motor comes up to speed. the switch opens due to the centrifugal force and allows the run windings to take over.

Q: Could someone explain the difference between a single phase AC motor and a multi (or three) phase motor. The info on the web is just confusing me. Thanks: single phase motor only has 1 phase wound on it's stator. These motors tend to run choppy. Three phase has all three phases wound on the stators ( + and - on opposite sides of the motor) all three phases are set 120 degrees apart around the stator (just like the phases of a 3 phase system). The function is not only to produce more torque but it make the motor run much smoother.

Q: is it necessary to use both ac and dc motor in car??: I thought DC only! Car batteries are low voltage device and short distance from the generator so no point to generate AC voltage and convert back to DC for charging the battery.

Q: I am in the process of learning about and building an electric go kart. I have several questions and am seeking help on electrical issues. I would like to power this kart with an electrical motor and car batteries, possibly chained together for more amps. I have several large AC motors and was wondering if a car adapter like this one: depends on the size(wattage output) of your inverter. you'd be better of staying DC
