FAQ

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.

can avr improve power from dc to ac inverter?

If, I understand your question properly? The most that the AVR chip will do for you? Is smooth out the wave signal of the AC power. As, AC over your home power lines comes in as a sine wave. Most common inverters are not capable of producing true sine wave. Most, at best produce a modified sine. Which means an inverter is just fine for small appliances. Like a coffee pot, small refrigerator, etc. But, create static and white noise for laptop, TV's radios, etc. These require a pure sine wave AC signal. So, yes, it will improve the purity of the power. But, nothing to boost/amplify power.

How the AC motor with DC power transfer

If the permanent magnet synchronous motor is used, the motor will be braked and the motor will be positioned at a fixed angle. Of course, we can not add full voltage.

What are DC and AC servo motors? What are the characteristics?

Into a DC servo motor brush and brushless motor, brushless motor has the advantages of simple structure, low cost, high starting torque, wide speed range, easy control, maintenance, maintenance is convenient but (for brush), will produce electromagnetic interference, the environment requirements. Therefore, it can be used for cost sensitive ordinary industrial and civil occasions. Brushless motors are small in size, light in weight, large in output, fast in response, high in speed, low in inertia, smooth in rotation and stable in torque. It is easy to realize intelligent, and its commutation mode is flexible. It can be changed by square wave commutation or sine wave commutation. The utility model has the advantages of no maintenance, no carbon brush loss, high efficiency, low running temperature, small noise, small electromagnetic radiation, long service life and various environments.

The direction of the flow in the pump with DC/AC motor?

If there is not any circulate out from the pump, then the impellers are only rotating the liquid around the impeller chamber. The artwork achieved is only to triumph over the resistance of the liquid led to via friction with the surfaces of the chamber. If the hole is open then the liquid might desire to go out the impeller chamber and new liquid will enter. The artwork the impeller now has to do is conquer the circulate resistance of the the entering and exiting liquid, which would be greater advantageous than the artwork interior the above, closed venture. that's genuine for the two centrifugal pumps and followers. so which you hear a vacuum air purifier's fan speed advance while the inlet is blocked.

What is the purpose of the encoder and how can you tell if it is working properly. thanks

The purpose for an encoder is to know where the motor is by revolutions the motor makes. Example: If you are opening a garage door with an encoded motor the encoder can tell if the door is closed or half open by the revolutions the motor makes. Hope this helps

Hi friends,Can any one help me to find the electric motor with 40HP and 500RPM for my project. RPM upto max.1000RPM is acceptable. Please help me. The motor should be available in INDIA. Thanks in advance :)

AC motors in that HP range are usually available as three phase, at RPM's of 1200, 1800, 3600. 1800 RPM is standard speed, so that will be the cheapest. To get down to 500 RPM, you have several options: Reduce the speed using pulley ratios. This is the cheapest if your application will accept it. Use a bolt on gear reducer. This is the best and most popular solution if you only need one output speed. Both the solutions above give you the advantage of reducing the motor HP to around 15 HP since you are reducing the speed but tripling the torque to that of above 40 HP. At 15 HP, you can switch to single phase if you have too, but stick with 3 phase if you can because they are much more efficient motors. Other options which give you variable output speed are an AC motor speed control (very expensive), or switch to a DC motor and controller (very, very expensive, if they even make them that big.) Search Baldor, Emerson, Lincoln or Grainger for motors. See Emerson, Grove or Boston for gear reducers, pulleys. See Gates for belts.

can you run a brushed ac motor on dc current?

Brushed AC motors are in fact serial DC motors. So, the answer is YES, you can. But you must do some maths not to overload it so it burns out. And (as in AC) it will not be a reversible motor! (i.e. if you reverse the poles, it will still rotate in the same sense).
