Q:What is the best choice?AC motor , DC motor, or Capacitor Start motor? Thanks!
I prefer a DC motor. A rheostat can be used to control voltage/RPM speed and DC motors are more reliable.
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 rotation!
Q:i have an ac 1 hp motor and when i rotate the motor with an 2T engine or any other which current does the mortor produces and i f the engine is rotating maximum at 500 rpm how much current does the mortor produces
Ac motor is not a generator but dc motor used as a generator.you can check current via multimeter in series of the load.
Q:I found a cheap washing machine motor that I want to use in my ball mill. How do I wire it to work from the wall outlet?
It is a single phase 115 volts AC motor. It has a capacitor sit at the top of motor or install some other place. It connects in series with the motor winding. It has two wires,plug them into power outlet,it shall turn unless it was defective.
Q:I think it's the coil, but I can't remember why. I think it has to do with the more surface for current to travel, but I can''t remember. Any help?
The simple motor tries to reach an output speed proportional to applied voltage. So the battery is the no. 1 influence on speed. The motor actually generates a back EMF when running (that's how it approaches a speed proportional to voltage; the lower the speed the lower the opposing EMF so the more current flows). Interestingly, a weaker magnet, or fewer windings in the coil, will also make the motor run faster; it has to in order to make the same back EMF. So both could be considered secondary influences on speed. EDIT: The AC requirement changes things. First, there's no battery. The simplest AC motor I can think of is an eddy-current motor, with an AC stator and a simple single-conductor rotor (e.g., a solid cylinder), a reduced version of the single-phase induction motor, whose rotor has either conducting coils or a squirrel-cage design with several conducting bars. The primary no-load speed influence is the AC frequency; the field strength and coil area affect torque. The next simplest AC motor I can think of is a synchronous type; AC on the stator coil and a permanent-magnet rotor. As long as it runs at all, it runs at synchronous speed determined by the AC frequency, e.g., 3600 rpm for 60 Hz and a dipole rotor. Assuming it's running with no load, changes in magnet strength or coil turns or current either stop it or don't affect its speed.
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:Siemens Motor 132M frame, 1450RPM, weighs 108lbs. Motor sat in a storage bin for 13 years, never wired-up or used.
as long as it was kept dry it's fine, bet that baby will do a number on your electricity bill
Q:Which motor has a great torque when the motor is under DC at the same power?
To sum up, the DC motor is still larger than the torque of the AC motor.
Q:I have a typical small DC motor which runs on 3-9 volts dc at thousands of RPM.Making use of wall power outlet and some resitors, can I run this motor properly? Will the motor run properly because of the 50Hz freq. of changing polarity as I am not planning to add diode bridges. If it might not run properly, then how to AC motors run normally?Thanks
Connected to an AC source, a DC motor will sit there and vibrate. DC motors work on magnetic repulsion by perfectly timed pulses. AC motors normally work on magnetic induction with either a rotating or ratcheting magnetic field. In most of them, the part that spins doesn't contain any coils or magnets at all. It's usually just layers of aluminum and iron. If you need finite details, Google is your friend.
Q:do conveyors use induction ac motors?
Yes, with variable frequency drives (VFD) there is a higher level of control of speed, acceleration and torque, so they can be used as well as any motor.
