Hi, anyone can tell me where can get control circuit diagram of motor for 220 V/ 4KVA motor drive automatic varic.?

hello i have a windmill with a generator that give`s me from 0 to 33 volt dc.

i want to load up a accu at 12v dc at all time`s even the time that the voltage is below 12 v dc.

can enywhone explane how to do that ,help me

i have LT GENERATOR .5 M,BUT POWER FACTOR (P.F) at load .7 need design power factor correction 200kvar

ask connection power factor correction, parallel after main circuit breaker

My customer wants to recycle water which has TDS about 300 after gravity settling in clarifier (outlet is below 20ppm). His worry is about possible deposits in the pipe lines due to TDS in water.

Question:

1. will this TDS level will cause any deposition in pipelines at normal te

Typically we use Air Handling Units (AHU) at large offices in India. Recently we are seeing variable Refrigerant Flow (VRF) system being aggressively promoted as something which is low-maintenance, more efficient system.

We have an old Brown and ..something.. surface grinder in the shop that neeed to be kooked up. The table is about 5" wide by 20" long.

Im am pretty sure it is a British machine.

Would you Brits have a good guess what voltage it likely needs, or what is a common supply voltage for i

Hi guys,

I am currenly in the midst of designing a system grounding for a 6.6kV 3 phase Generator.

Basically, i am just following my customer's specifications for the system grounding according to their Single Line Diagram.

They have rated their Neutral Grounding Resistor

I would like to create a very large adiabatic decompression device. My goal is to force the majority of the ambient water vapor(humidity) to go through a phase change back into liquid (like a fog). How would you design a machine that could adiabatically decompress 5,000 cubic meters of ambient ai

Kindly inform me how I can calculate the nominated Voltage test value required for Megger Testing of 11KV motor.

your kind immediate reply is highly appreciated.

This is driving me nuts. I am looking for a source for what I have always called a ball-and-ramp actuator or ball-and-ramp cam. They have been used on motorcycles for clutch release, and look vaguely like a ball thrust bearing. If you took all but four of the balls out of a thrust bearing, and pu
