A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...
Home machinists can often find great deals on used industrial equipment, and many a South Bend lathe or Bridgeport milling machine has followed someone home. Then comes the moment to plug it in, and ...
Hardware-Software Solution for Three-Phase BLDC Motor Inverters Enables Greater Than 98 Percent Efficiency, Saves PCB Space and Speeds Time-to-Market NUREMBERG, Germany--(BUSINESS WIRE)--Embedded ...
Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...
The QAS 45 generator has an Isuzu 4LE2X diesl that achieves Tier 4-Final with a DOC. Output is 480/277, 208/120, and 240/139 volt 3-phase settings; and 120/240 volt single-phase. A 72.5-gallon fuel ...
The QAS 200 Atlas Copco generator is a new unit, delivering 200 kVA/160 kW. It has a John Deere 6068 diesel engine, and is dual frequency capable. An AREP alternator excitation system enables quick ...
This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...
Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...
