Q:Does the power (current * watts) by an AC motor = the heat produced ?
Short answer: take the BTU rating and add about 1/6 more to account for the power consumed by the motor to get the total maximum heat rate dumped out the dump If the A/C motor consumes 6 amps of 120 volts, then that 720 watts that needs to be dissapated somewhere, somehow. About 15% will be wasted in the motor for a single-phase motor and 85% will be do useful work (and ultimately end up as heat. 0.720 kilowatts x 3413 BTU/hr per kw = 2460 BTU/hour Refridgeration, depending on the coolant used and the temperature range (inside versus outside the cabinet) have efficiencies of 4 to 11 or so. Let's try 7.5. So 2460 BTU/hour of electrical power consumed x 7.5 = 18,000 BTU/hour of heat moved from inside to outside. Add the 2460 (motor) + 18,000 (cooling) and there's your total heat dumped out the back of the cabinet. Note that A/C systems often have duty cycles and all of the above is about peak rates. When the cabinet contents generated a lot of heat and its a hot day, the A/C will run for a long time. If the contents are unpowered, the duty cycle of the A/C might 10-15% of the time.
Q:The difference between AC motor frequency conversion speed regulation and voltage regulation speed regulation
Variable frequency speed regulation: large speed range, high smoothness, energy saving, can realize constant torque or constant power speed regulation, but must have dedicated frequency conversion power supply, the cost is high.
Q:synchronous motor operation?
both of the two people above are correct in their formula, one uses 120f/no. of poles, the other uses (60)f/pole pairs which are equal, besides poles are always pair in either motor or generator windings.
Q:What are the features,characteristics and applications of an ac motor?
ac motor? do you want to ask about AC (Air conditioner) Motor?
Q:Why capacitor is needed in single phase ac motor?
Single phase motors (some of them) require a capacitor to create turning torque for the armature. Once started, these capacitors are disconnected from the circuit by centrifugal switches. Some small motors use a shaded pole to apply the torque to start the motors. A capacitor connected in the circuit creates an essential magnetic force which imparts a torque to the motor similar to the action of bringing similar poles of two magnets together. Like pole repel.
Q:How can i slow the RPM on an AC motor?
The motor you are describing is a synchronous motor; the speed cannot be changed easily. Variable frequency as suggested $$$$ can do for a bit, maybe 20% So you are stuck with the gear thing, I would suggest that you get a few BBQ motors at a local store because it has all the gearing. A few, because they may not last for the entire job depending on how well balanced is the load (the pig) If the load is well balanced, meaning that the effort is constant throughout the revolution then the BBQ motor will do fine. If the motor has to break the rotation in some portion and supply enormous torque in other portions it will die on the job I hope this answers your question
Q:AC Direct Drive Motor question?
Q:Relation of voltage, speed, voltage and torque of single phase AC motor
The speed and frequency are the same, because the supply voltage is constant, the frequency of the change, the result of direct reaction is the same speed change, frequency increase, speed also increased, it minus the other also reduced.On voltage analysis, look at these formulas.Motor stator voltage: U = E + I * R (I is current, R is electronic resistance, and E is inductive potential);And E = k * f * X (k: constant, f: frequency, X: flux);For asynchronous machines, T=K * I * X (K: constant, I: current, X: flux);It is easy to see that the frequency of F changes, is also accompanied by the change of E, voltage of the stator should also change, frequency control methods commonly used in fact is that, when the frequency changes, the inverter output voltage, also is the increase in voltage at both ends of the stator is changed, is proportional to the this is the ratio of frequency conversion constant V/f. Analysis of the three equations can also be used in front of the same results can be obtained.
Q:Why is AC motor control more difficult than DC?
In addition, the DC variable voltage is easy to realize and the communication is troublesome. Therefore, the AC speed regulation uses frequency conversion speed regulation more frequently, but the frequency conversion speed regulation system is more complex than the DC voltage regulation speed regulation.
Q:AC Fan Motor connection?
In a vehicle the fan motor runs from the battery whilst the A/C compressor runs from the engine. The A/C fan motor runs each and every time the automobile's fan change is located in between the ON positions (and the secret's 'ON', etc.). many times the person would desire to decide on the Snow Flake image on the dashboard to instruct on the A/C. besides the undeniable fact that, till the engine is working the A/C compressor isn't doing the paintings needed to make chilly air (different than the A/C fairly runs additionally whilst interior the defrost place on the that different fan administration knob). in case you decide on the snowflake image and the fan is ON and the engine is working and the ignition key's on and you at the instant are not interior the defrost place and you do not have some style of fault interior the equipment then you certainly would desire to get chilly air out of the vents given which you furthermore would have the temperature slider set to grant chilly air too.
