Q:I dont need to control the speed. What is the easiest way to convert and what would be the least expensive way. Thanks.
What is the nameplate rating for this motor ? Voltage Running current Locked rotor current You will have to get a AC-to-DC power supply, it can be made from an autotransformer and rectifier bridges, but it won't be inexpensive, or you can buy an industrial power supply for several hundred dollars. I could not find one on Google with a quick search; that motor is too large for the 2-horsepower supplies I did find. A 2.25 hp motor is difficult to start and run on 110 V AC power because the running current will be a minimum of 15 amperes, thus requiring a sized 20 amp or larger. You will need motor overload circuit protection which is sized for the current requirements of the motor. The starting current for the motor, if the motor has a heavy load, will be more than a 20 amp breaker can handle, so you really need 30-amp service.
Q:What is the principle of the single-phase AC motor in the washing machine?
The motor of the washing machine should be called: capacitance type single-phase asynchronous motor. The principle is a series capacitor in the amount of the starting winding, the voltage and current of capacitor lags behind its 90 degree, it will produce a magnetic field in the stator, the motor rotating motor! Static centrifugal switch is turned on when the electric starting capacitor in after starting work, when the rotor speed reaches the rated value of 70% to 80% when the centrifugal switch will automatically jump, starting capacitor to complete the task, and disconnected. The running capacitor is connected to the starting winding to participate in the operation. This method is generally used in air compressors, cutting machines, woodworking machines and other heavy load and unstable place.
Q:I know many AC motors don't have brushes but there are some that have brushes. How do you call that type of motor? Thanks!
If you are talking about a single phase motor, its likely a universal motor. These are often found in domestic appliances such as vacuum cleaners or washers. If you are talking about 3 phase motors, then one type is a wound rotor induction motors. There are usually 3 sets of brushes and rings that allow resistances to be connected into the rotor circuit. Large synchronous motors will also have brushes (except brushless, of course). These supply the rotor with the DC excitation.
Q:Hi friends,Can any one help me to find the electric motor with 40HP and 500RPM for my project. RPM upto max.1000RPM is acceptable. Please help me. The motor should be available in INDIA. Thanks in advance :)
AC motors in that HP range are usually available as three phase, at RPM's of 1200, 1800, 3600. 1800 RPM is standard speed, so that will be the cheapest. To get down to 500 RPM, you have several options: Reduce the speed using pulley ratios. This is the cheapest if your application will accept it. Use a bolt on gear reducer. This is the best and most popular solution if you only need one output speed. Both the solutions above give you the advantage of reducing the motor HP to around 15 HP since you are reducing the speed but tripling the torque to that of above 40 HP. At 15 HP, you can switch to single phase if you have too, but stick with 3 phase if you can because they are much more efficient motors. Other options which give you variable output speed are an AC motor speed control (very expensive), or switch to a DC motor and controller (very, very expensive, if they even make them that big.) Search Baldor, Emerson, Lincoln or Grainger for motors. See Emerson, Grove or Boston for gear reducers, pulleys. See Gates for belts.
Q:The pack is 12v and I really don't have any experience with electrical engines, only gas.
Fisher-Price battery packs are a disappointment to many Fisher Price, riding toy owners. You are probably better off considering a motorcycle, car, or deep cycle marine battery. This does bring up a set of issues that electric vehicle makers have in general: cost, weight, volume/space, and bracketing for the batteries required. The next set of issues relate to charging systems; you might want to visit a couple of automotive and RV shops to get an idea of the considerations involved in selecting a charging system of which cost is only one. It also sounds like it is time to learn more about electricty, physics, and electrical motors. I'm sure that there is a reasonable amount of information available for free on the internet. But, the library is a great source for free information too.
Q:How do I test an AC single phase electric motor with a meter to see if it is burnt?
Ideally you need a megger but you may detect a fault with a multimeter but it will only tell you if its bad not if its definitely good. A single phase motor has 2 windings. Test each one (any wire) to ground. You should have a very high reading (many millions of ohms). You should then be able to test a circuit through each winding but not much way of knowing the resistance unless you have an identical motor to check against. If it has a contact to open the start winding, then this should be checked (closed stopped) as it is a common fault and easy to test. If it has a capacitor then try replacing it.
Q:the motor is 580 watts ac motor 11000 rpm 50hz i need to know the hp of the motor
1 horsepower (hp) = 745.699872 Watts Therefore, 580 Watts = 0.777792812 hp.
Q:I have this AC single phase motor, 115 volts at 1800 RPM. If i spin the shaft faster than 1800 RPM will the voltage stay the same, increase, or decrease around 115 volts?
Also, the mechanical design of the motor may not be designed for such speed. Vibration and wear may decrease the life of the motor without enough load to slow it down. The motor may start to screech from such vibration and oscillation.
Q:I was wondering how much would it be to replace the heater blower motor on my car and also how much the labor costs would be?.
Get estimates from at least three places. That's what I'd do if I weren't willing or able to do it myself.
Q:I want to put a quot;dimmer switchquot; (like the kind you put instead of a light switch to control how much electricity the circuit gets) before an AC motor running on 120 volts. Basically, we needed a motor for a project and it has a switch already on it for 2 different speeds of 600rpm or 1200 rpm (It was from a rather large industrial fan). I need it to spin slower and i was wondering if it will damage the motor to give it less voltage with the variable switch, or if the motor will run at all.Thanks in advance
An industrial fan will be ok on the dimmer switch, as long as the dimmer is rated for that power. Check carefully to be sure that it is. This won't hurt the motor.
