- Q: Common problems of AC motors
- Prevention: (1) eliminating the pulsating flux and power harmonics (such as in the inverter output side with AC reactor); (2) motor design, the bearing seat and a base bearing insulation insulation cover, the outer ring of the rolling bearing and the end. 2, why can't the General Motors be used in the plateau area? The altitude has adverse effects on motor temperature rise, motor corona (high voltage motor) and commutation of DC motor. We should pay attention to the following three aspects: (1) the high altitude, the motor temperature rise, the output power is small. But when the temperature drops with the elevation, it is enough to compensate the influence of elevation on the temperature riseWhen the rated output power of the motor can be changed; (2) high voltage motor to take anti corona measures in the plateau; (3) altitude against commutation, be sure to use carbon materials. 3, why should not the motor run light load? When the motor is in light load, it will cause (1) the motor power factor is low; (2) the motor efficiency is low. Will cause waste of equipment and uneconomical operation. (1) the load is too large; (2) lack of phase; (3) the air duct is blocked; (4) the low speed running time is too long; (5) the power supply harmonic is too big.
- Q: Hey guys, my AC tries to start outside it seems, but then i hear a big BEENG sound for like 4 seconds (as if the AC tries to start). Then it stops. I have a digital thermostat and its showing all 8888. I tried to stop the circuit breaker and restart it to no avail. It's the unit outside that seems to be the problem.ANy clue what's going on here and how much it will take to fix it?
- It appears like a situation with the burden on the motor to me. The Cap is barely for beginning,you ought to have a initiate winding going undesirable or something is preserving the motor back at startup, or centirfigal change that cuts out Cap is improper.
- Q: i am restoring a old table saw. With the table saw came a westing house, a-c motor. At first i plugged in the motor and it just made a buzz noise.(didn't move) SO, i took of the the two cut wires it had, and plugged it in with the ground- on, well, the ground. it made the same noise then i pushed it and it went. yeaaaaa!!! buttttttttt i tryed it again and it went the wrong way???????? idk what to do. there have to be 4wires connect it to it, two i think go toelectricityy and two i don'tt know and there is a ground-whichh i have set up? sry is so long thanks for help.
- But the model number or more information about the motor is really needed to help you much more than that.
- Q: Relation of voltage, speed, voltage and torque of single phase AC motor
- Motor power: P=1.732 * U * I * cos PhiMotor torque: T=9549 * P/n;Motor speed: n=60f/p, P for the motor pole count, such as four motors p=2;Note: when the frequency reaches 50Hz, the motor reaches the rated power, and then increases the frequency, the power will not increase, and will maintain the rated power.The motor torque is less than 50Hz, is proportional to the variation with frequency of F; when the frequency reaches 50Hz, the motor reaches the maximum output power is rated power; if the frequency of F in 50Hz and then continue to increase, the output torque is inversely proportional to the frequency change, because its output power is so big, you have to continue to increase the frequency of F, then the formula set in the above analysis, the torque is obviously reduced.
- Q: After taking out and cleaning and coaxing the AC fan motor in my attic over the past year, I have finally removed it for good and ordered a new one along with a new capacitor, all from Grainger for around $220. This motor sits in a squirrel cage surrounded by a fan. The heat pump is located on the outside of the house. The old motor's connecting wires are red and yellow and black. How can I identify the right connections should the wires on the new one I'm picking up tomorrow have different colors? I am depending on the Grainger guys to correctly identify the correct connection to the capacitor. I do all this myself because I'm on a disability budget and have managed most similar repairs for over a decade. It's not always easy but the willingness to learn has always benefited. Thanks for guidance.
- You are more then welcome. Helps keep my idle mind working. Every fan motor I have seen has the color code in the label. Common, should be 2 browns for the capacitor and 3 or 4 colors for the speeds. Check your old motor and write down what color is what speed. Now check the new motor and match the speed to the color. In most cases I have found them to be that same. Almost a industry standard. It may even tell you how to reverse it should it be running in the wrong direction. If the old motor did not have this or you can't make it out, then you need to check the wiring diagram for your unit. Should you need more help, please tell us you model number and the motors Grainger number. I have kept my acct. with them open. I notice that you are picking the motor up tomorrow. Take the old motor with you to compare. Check the new motor's name plate for that wiring diagram.
- Q: Why are brakes on AC motors normally DC? Is it because they use an elctromagnet and maybe they work better on DC?
- The best advise i can offer you is to to check in the electronics mart then if that fails contact the manufacture...
- Q: I just got charged $889 to install a new motor and capacitor. Plus $89 to add frion.
- Some motors are cheap, some aren't! I've found that with electrical motors you really don't want the cheap one as it'll cost even more to replace it again and again. Could be that the a/c tech was selling you a motor that was first bought by the a/c manufacturer, then bought by the a/c techs service company, then finally bought by you, each company in the chain marked it up. The motor might say 'Trane' (for example) but be made by Baldor from Ft Smith, Ark. Also you mentioned 'freon', well not just anybody can handle that stuff, Federal Law, only a certified HVAC tech can even buy it
- Q: are the electric motors used by the toyota prius dc or ac?
- To help you with the confusion of AC or DC, it depends on at electrical power input point you look at it. The motor systems includes a permanent magnet synchronous motor driven by an inverter controlling the motor. The battery supply, which is DC, goes to the inverter then it is converted to variable-frequency AC power by the inverter before feeding the permanent magnet synchronous motor. Hope this helps!
- Q: How to synchronize two ordinary AC motors?
- The motor does not need to be synchronized. As long as the same type of motor on the line, the two sides automatically run at the same time into the synchronous state. As long as the load on both sides of the motor is not the same. When a motor is switched a little faster, the load of the motor is increased, the speed of the motor is slowed down automatically, the load of the other motor is reduced, and the speed of the motor is increased naturally.
- Q: How to run a dc series motor in ac? Will it limit its characteristics?
- hi. AC automobiles are designed and outfitted in a different way than DC automobiles. AC automobiles earnings on the 60 hertz clock of a capability line (or 50Hz in different countries) - this suggests the capability line ameliorations stages 60 cases a 2nd - to rotate, whilst DC automobiles are designed with the voltage point utilized. you are able to administration them the two, yet with different skill. the simplest to regulate is the DC motor (replace the skill (the voltage) and it turns slower or quicker.
