Overview

YVF(E) three-phase asychronous motor for brakingv is provided with an electromagnetic brake set between the rear cover of the primary motor and axial-flow fan
This kind of motor is widely applied to the occasions requiring for speed regulation, rapid stop and accurate positioning.

Features

Variable-frequency regulation in a broad range;
High efficiency, small starting current and big starting torque;
Capable of rapid braking and accurate positioning. It is suitable for frequent starting and braking

Q: Is it possible to have an AC current applied to a DC motor ? How about an AC motor with DC current? how is this done?: AC power to DC motor ----- motor shall not run at all and heats up. DC power to AC motor ---- it runs at the beginning then burn out.

Q: Boyfriend is trying to repair our window AC unit. He says the problem is the fan motor (not the compressor, etc). It'll run and cool the room for a little while (20-30 minutes maybe) and then it will die. We can wait and turn it back on, but it always dies after a little while. What exactly could be wrong with the fan motor?: will you do us a favor, and post pictures of him changing it on this site. And tell him hes gotta do it without breaking any plastic parts and cant bend any of the coils when he takes the blades off both sides of the shaft. And no swearing when he puts the clip back on the squirrell cage. Actually you can unscrew and GENTLY move both coils out of the way, but dont bend the freon lines too much, just enough to get to the blades.

Q: The direction of alternating current keeps changing. How about the direction of AC motor?: The direction of rotation of the AC motor is not determined by AC + Half direction, but by the alternating current through the processing of a certain way to produce a rotating magnetic field acting on the rotor, as you hold a permanent magnet in the circle around the same compass compass as the principle of rotation make the rotor rotate, it the rotation direction depends on the direction of rotating field.

Q: I have 2 dc motors running off a 12 volt battery charger. It works but the motors run very slow. What can I do to make them run faster. Can I use a power inverter to convert 110v, ac into 24v, dc?: first check is the current supply on by touching the main wire

Q: For example, I have an old fan. How do I modify the motor to generate electricity from the wind?: Oh man I just Loved jenifers answer - very practical! For the simple reason it is impossible to reasonably convert a single phase induction motor to be a generator of useable electricity ...

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.: It may be you a/c compressor. If you leave your a/c on when you turn off and start your car it is bad for the compressor. You would be very lucky for it to be a relay. I'm not positive where the relays are located on a versa though. Goodluck!

Q: How to distinguish AC and DC machines: The main difference between AC and DC motor is the power properties of different AC motors using AC generator, the AC and DC motor; using direct current, the generator is DC. Advantages of DC motor (AC motor and more): smooth speed control characteristics, can achieve economic. And AC motor need to use inverter, electromagnetic regulator and other components to achieve this function.

Q: The difference between a direct current motor and an alternating current motor: As the name suggests, the direct current motor uses DC as the power supply. AC motors use alternating current as power source. Structurally, the principle of the direct current motor is relatively simple, but the structure is complex, and it is not easy to maintain.

Q: AC servo motor why drive?: Servo motor control is more complex, you need to change the frequency, voltage, current, in order to achieve the motor speed, torque, position of the overall control, servo drive is dry. The servo motor is only responsible for how much frequency and voltage you give me, so I'll do the right thing. Changes in frequency, voltage, direction, etc., are handled by the servo controller.

Q: Can AC motors be converted into generators?: Another method is to replace the original rotor directly with the one or two pole permanent magnet. Note: the poles of the permanent magnet should be as close to the stator as possible, but they cannot be touched. Rotating the rotor (or permanent magnet rotor) can pass the stator around the output voltage, current. If the speed is increased, the voltage can be mentioned very high.
