Remember, when wiring motors for a certain voltage, the service technician must always refer to the motor manufacturer’s literature and numbering scheme before wiring the motor for the desired voltage or damage to the motor’s windings may occur.
Too often, compressors get replaced when an external component, such as a defective start relay, start capacitor, or overload, is the true cause. A technician must always check these components before condemning the compressor.
The Alfa Laval T8 gasketed plate heat exchanger can be used for HVAC applications in buildings and numerous other industries such as fluid power, metalworking, marine, power generation, general manufacturing, general utility cooling, engine cooling, and the semi-conductor industry.
Voltage unbalances exceeding more than 2 percent in three-phase systems can cause current unbalance among the windings. These voltage and current unbalances can cause an increase in winding temperature and an overheating problem that can be detrimental to the motor.
