Siemens High Low Voltage Motor 1PQ Series

Q:if it is to be observed from some distance with same color wires supplied.: If you see a cylindrical bump on the frame of the motor, it has an external starting capacitor and is therefore an ac motor. Not all ac motors have them so you cannot tell if there is no capacitor.

Q:i have an old electrical blacksmith blower. the motor doesn't include a built in transformator. it just needs an it has an input of 3 Amp and 28 Volt.but i don't know if it's Alternating or Direct current.how do i test this?: Cut the wire, and connect with an LED rated for that amperage/voltage. Turn the LED around so and test to see whether it lights one way or both ways. If it lights in one direction, it's DC if it lights in both directions, AC. Chances are that it's a DC motor, and requires the input cable to have a small transformer(usually situated right next to the plug) **edit** I may as well explain why this works. An LED will only light if the current is flowing through it one way. With DC it will light only when the current is flowing through it the correct way. With AC current, it will strobe regardless of which way the LED is aligned.(but probably too fast to notice)

Q:What are the direct and alternating current motors used in daily life?: Friends, DC motors have toy motors, toy cars, toy planes, razors, rechargeable power tools, and in short, all batteries or batteries are DC motors. AC motor home pulverizer, threshing machine, ragweed machine, milling machine, water pump, submersible pump, booster pump, blower, electric fan, compressor, grinding machine and so on the use of electricity directly to work is AC motor.

Q:In a motor, in the middle, coils are used and they are magnetized when AC current flows through them.I have found permanent magnets are being placed fixed with some distance around these coils for producing deflection and thus the motor runs in some motors.Does a 7.5 HP AC motor also has permanent magnets?: 7.5 HP AC motor does not need any permanent magnets. Same to all different kinds of AC motor, they do not need permanent magnets. But a small AC generator needs permanent magnets.

Q:It is an older motor, but runs well... except that it doesn't always start in the same direction. When I switch it on, it hangs for a second and then starts in either one direction or the other.: Either the starting capacitor is worn out, or disconnected, or the centrifugal switch is not working, or the startup winding is open or disconnected. See the image in the source below.

Q:i want a fairy simple one that doesn't take too long time or not too complecated, thanks.: If you have a strobe light you can confirm that it is turning at just under 60 cycles/s because the AC is 60 cycles/s You can take off the fan blade and confirm that it is now turning even closer to 60 Hz because of a lack of load. You can increase the load by blowing air at the fan with another fan and watch it turn slower. If you can destroy the fan (there are many being thrown away each day) you can cut off the copper shading coils that help it start up. You can measure the current in all the above situations and observe that the closer to 60Hz it turns the less current there is.

Q:Now I will start off with that I have had no issues with this vehicle yet unlike some other Versa owners. Short story is whatever idiot replaced the battery right before I bought it didn't properly tighten the cable onto the terminal. So it popped off. This was easily fixable by repositioning it and tightening it down. Well the bad news is at some point or another when I tried to start with the battery partially connected (I didn't realize this was the case until I tried starting a couple times to no avail) it must have surged and blown something out in the AC electrical area. I checked all fuses, they're good. I looked at the service manual and there appears to be a relay between the switch and the compressor. So I'm hoping its that relay. The options that remain are relay blew, which is quite possible, or the switch or the BCM that controls the switch got surged or blown. Any thoughts? Also I haven't been able to locate the relay yet, do I just need to pull the dash to get to that? Thanks.: see ur mechanic and get a diagnosis ,,before you start ripping apart the dash,,to replace something that may not be bad

Q:I have a 2001 BMW 325i..the air conditioning completly went out about 2 weeks ago, nothing would work. I took it to a repair shop m,y buddy owns (so i know he didnt cheat me) and they said it may be the blow motor, so they fooled around with it and it started working after 5 minutes of messing with it it automatically came on and started working. They said the antifreeze was low so they filled that up also and I was on my way....about 3 days of the air conditioning working fine, i came out side and id had the ac on high went i turned the car off and it was still on....now even if the cars off the air still blows on high, if you try to turn the air off or turn it down its still on....what could it be??????: bad ac switch. its not sending the right signals or maybe no signal

Q:How to realize constant power or constant torque output of three-phase AC motor?: Is generally achieved through the frequency converter in the frequency power supply 50HZ, with inverter motor, the inverter output is below 50HZ, the motor is in constant torque output, but the inverter output is higher than 50HZ, the motor is of constant power output

Q:I have an air compressor AC motor and when I plug it in, it acts like it's not getting any power at all. My thoughts are the the reset switch on it is broken. Could that be it, or could the windings on the motor be bad?I've already replaced the start and run capacitors, so those work. The reset switch just seems to be in bad condition. If so, is the reset switch a special kinda one? And where could I get one?: Some electric motors have a governor device on them to automatically switch from the starter capacitor to all ac. Those switches can go bad and will cause this type of problem. If it is the reset switch, or any other type of switch, good luck in finding one. I have these switch issues at work and can not find them. Had to replace the whole motor. Good Luck
