Q:How would you measure the resistance of a 2-pole, 3-phase AC induction motor?
Dear, Thanks, am also fine like you,for remind always during measuring resistance do not switch on the system, by use megger please check the resistance between one terminal @ body another be each one end of 3phase input to motor.Ensure it must be open now the winding resistance between any 2 of 3phase input to motor.it should offer some resistance in ohms.
Q:New AC to DC idea, but will it work?
Yes, it will work, but it's not nearly as efficient as the traditional method of a bridge rectfier and capacitor bank. The AC motor will not be more than 90% efficient, and the DC generator will not be more than 90% efficient, so the whole assembly will not be more than 81% efficient. The bridge rectifier/cap bank will easily be more than 95% efficient.
Q:a starter capacitor of 6mf on a 240 volt electric motor question?
It's for starting the motor. Many AC motors work fine as long as they are moving the least little bit. But from a dead stop, the capacitor provides a phase-shifted voltage to an extra winding that gives a little bump to get the motor going.
Q:What part of the simple motor-wire coil, magnet, or battery has most impact on output of motor (rate of spin)?
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:What is the essence of motor rpm in industrial applications?
An induction motor is going to cost below a synchronous motor. An induction motor has slip and a synchronous motor does not. check out the 1st paragraph on wiki below. So which a million is greater valuable has greater to do with money than the burden.
Q:Do blenders use AC or DC motors?
Most blenders have brush-type motors that look like they could run on DC, but they can't; they run on AC only. Check the ratings on the bottom of the housing of any given blender to find out for certain. I would normally expect to see the words AC only there.
Q:What about a single phase AC motor reversing?
The steering of a single AC motor has different rotating principles according to the structural differences. The following is a reference for professional data:Single phase motors are usually divided into four types: split phase, push cabinet, hood type and ordinary series excitation type. Since the structure of the four is different, the method of changing its rotation direction is also different
Q:How do you build a very simple, very basic 120 Volt AC induction motor?
For wire wrapped around nails or something, use a lower voltage. Look at descriptions of how motors work and compare AC motors with DC motors. A permanent magnet AC motor might work better than an induction motor. Study all the kinds of AC motors. Single-phase AC motors usually need capacitors. If possible, wind the wire on something U shaped and put the rotor between the ends of the U.
Q:How much does it cost to replace a AC motor and capacitor?
Was it the indoor fan motor for the furnace/air handler or the outdoor condenser motor? It sounds like the tech felt bad about overcharging you for the fan motor and gave you a deal on the Freon. He probably didn't add much Freon. There are no $889 fan motors (not for a 1200 sq ft townhome), there are only customers willing to overpay for a $350 motor. You said it was an AC motor. DC motors are more expensive.
Q:Should I use a DC motor for a variable speed mechanism or an AC motor with an inverter?
Hi. AC motors are designed and built differently than DC motors. AC motors take advantage of the 60 hertz clock of a power line (or 50Hz in other countries) - this means the power line changes phases 60 times a second - to rotate, while DC motors are designed with the voltage level applied. You can control them both, but with different means. The easiest to control is the DC motor (change the potential (the voltage) and it turns slower or faster.
