Q: I have AC motor with star/triangle that blow the fuse after 30 seconds it started: Bluto B also has a good point. There is a centrifugal switch that is supposed to cut out the low speed starter windings on may AC motors, and if that were stuck, it could cause excess drain.

Q: Its design for a 20second operation. Pass decades, it working perfectly ok. However, lately, sometime after an operation, it rotate the other way, and then for the next turn, it rotate perfectly again... :(: Depends on the motor. Some small motors have a cam that prevents reverse rotation if this is the case maybe it has stuck possible a bit of grease in the wrong place.

Q: I have it all disconnected and out of the unit. I am having trouble getting the blades off of the rusted shaft. (two rusted set screws) Any tricks out there on how to loosen them without damage to set screws? Any other advice would also be helpful...first time at this.: ive done alot of them and they are not any fun. I like pb blaster to spray on them and let them set for a bit then give it a try

Q: Does the DC motor work the same as the AC motor?: 1KW DC motor with 1KW AC motor is not the same, 1000 Watt DC motor will be a lot of small volume, although the power is 1000 watts, DC motor torque is relatively large, speed control is relatively easy. The DC motor is more powerful against overload, but the price is more expensive.1KW DC motor can bring a large generator, 900 watt generator, the actual output power of power generation is at most 800 watts. If you want to get the power of different types, using a motor driven generator is one of the most stupid way to use the lowest efficiency, power supply module, the highest efficiency, fast response, easy to adjust the noise to a minimum, the price is the cheapest.

Q: I used my ohm meter and find the pairs and number at random, 6-3, 5-2, 1-4, then I found my last 3 leads that showed continuity and number at random 7-8-9...then I wired the motor for 208 3ph as follows, 4-5-6- togethers,then 7-1 for line 1, then 8-2 to line 2, and 9-3 to line 3, the motor it is not grounded and the leads are not open, m' I missing something or the motor it's not good?: **** in it

Q: Siemens Motor 132M frame, 1450RPM, weighs 108lbs. Motor sat in a storage bin for 13 years, never wired-up or used.: Inside? The centrifugal switch might be kind of sticky, and the contacts might be dirty. But if was kept dry, it should be just fine. Outside? It's toast.

Q: Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?: AC motor: wind, make the sound small, more durable, hot and cold big difference, large volume, stable current to prevent overvoltage protection AC fever dead machine, most hair dryer is now all communication, have built-in motor protection diode

Q: I am connecting a 400 watt electric motor to my bike, along with a inverter since the motor runs of ac power. I am trying to find someway of adding a new and separate gear onto my bike without damaging the bike, or welding anything, and making the device possibly removable. I am hoping to run a chain from the motor to the gear I added on.: anything is possible if ya study it long enough. try different parts off of different things till ya find a combo that works. main thing is dont rush into it,patience and some good ol thinking on the problem can make anything work. look at all the custom rods out there with home made parts on them. think it out and you will make it work

Q: and act as a brake or actuator? I realize an electric motor can act as a brake but can its position be locked solid?: not an ordinary one. A stepper motor can. Blocking movement with an ordinary motor, normally possible only if gearing is involved and a delicate adjustment of forces/current is done requires a fairly high current flow and can burn out the stalled motor.

Q: Motor PWM how to speed?: PWM speed control principle of AC motor and DC motor speed control principle is different, it is not through frequency modulation to adjust the motor speed, but by adjusting the driving voltage of the pulse width, and the circuit of some energy storage elements, change the delivery to the amplitude of the armature voltage, so as to achieve the purpose of changing the speed of DC motor. Its modulation mode is amplitude modulation.
