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:Which motor has a great torque when the motor is under DC at the same power?: If the DC / AC motors operate under the rated 800W output power, there is no doubt that, as long as their speed is the same, the output torque is the same, which is a static consideration.

Q:Im designing a twin screw extruder, and I am using an AC motor to power it. I will have a gear box with a reduction of 10:1 and 2 out but shafts. IE motor gives 3000RPM I want the 2 screws to rotate at 300RPM. the torque at this speed should be 15Nm what will happen to the torque after its placed to 2 shafts and does it increase 10:1 through the gearboxs as the speed is reduced?Thanks folks!: either shaft can deliver the full torque if the other is not loaded. The sum of the two loads has to be less than the specified torque, minus friction losses. yes, reducing the speed by a factor of 10 will increase the total torque output by that same factor, less friction. .

Q:just bought an inverter. is it possible to connect a small motor with alternator to the AC generated by the inverter, and then use as a charger to charge the battery connected to the inverter so that as the battery is giving power to the appliances connected to the inverter, the charger is charging the battery thus ensuring that the battery wount go down?: If this simple idea worked, it would be making more energy than it expended, which as of yet hasn't really been done.

Q:All I have is a motor, fan, a plug, and about 5 or 6 wires sticking out of one side. How do I get the motor running?: It's an AC motor, you can't run it from DC, which is what i assume you mean by power supply. Someone answered this question the last time you asked, with details on how to connect the wires to an AC outlet. .

Q:what might be the sypmtoms, if theres a problem with brusehs or/and slip rings of a DC motot and of an AC motor ?whats the solution of this problem ?thanks: If you isolate your question only to the rings or brushes, you can narrow possible problems down to corroded/worn parts, overheated parts, or poorly installed parts. The symptoms will most likely be the motor not functioning at all, refusing to start itself but will run with a little helper push, noises from the end with the parts, or a completely locked up motor. The solution to the problem is most always replace the worn parts. In most cases ive seen tho, if the rings or brushes have worn naturally (without the help of careless operator), other parts are getting ready to go out (bearings, coils, and such). The symptoms can differ between the types of motors as well and always check the input power source and controller before you pull the motor apart.

Q:Even when I put the AC 78 the house will get really hot..when we check the AC..the motor is frozen. We then have to turn it off for it melt and the ac will work again until it freezes. Any suggestions as to what can be wrong, what parts need to be replaced?No we don't need a new ac...: Check that supposed air filter in the front. Clean if necessary. Next go outside if possible, and see if there is alot of water collected at the bottom of the A/C Unit. If so, most likely the drain is clogged up on it. Need to get that mold and stuff out. Hope this helps a bit.

Q:what are the names of AC motor driver IC that are manufactured in India? list some names of the IC ?: If it is Fan Motor It is only TRAIC 800-1200 PIV, 2 -10amps Your Question not clear -Give details of your AC motor ? Where it is used ?What is the capacity?Is it a simple fan Motor? Is it Used in Lift elevator ? or used in Railways Traction Motor ?

Q:i have 230v 750w ac motor , can it run in 100AH dc battery?: You cant use an AC motor with a DC power source. you will need to have an inverter to change the DC to AC and a 100ah battery is like the one I might find in a computer where you would probably need a 4000ah battery to make it worth wild

Q:Does anyone know the following,the starting and torque as awell as speed and load?and to be picky does anyone know them for a three phase AC motor?: Starting torque for both is about 250% or more of rated torque. For DC shunt motor, see curve in 2nd source. For ac, see NEMA curves in 3rd source under DESIGN A, B, C, D - FOR AC MOTORS Speed and power depend on motor you buy - check manufacturer catalogs. AC motors typically run a few % below following synchronos speeds: 1800, is most common, also 3600, 1200, 900 rpm. You can use the internet to look for catalogs and more info.

Q:lionel trains: I am not understanding your question; Lionel Trains normally use reversible universal motors and are run on AC.
