What is the measured motor voltage for a screw compressor?

The measured motor voltage for a screw compressor typically aligns with industrial standards, particularly in the North American market. A voltage of 480 VAC is common for large industrial motors, including those used in screw compressors. This voltage level supports the efficient operation of the compressor, ensuring adequate power delivery while minimizing electrical losses.

In industrial settings, 480 VAC is frequently utilized due to its balance between providing sufficient horsepower to drive equipment and the infrastructure available for handling this voltage without requiring extensive modifications or specialized equipment. This makes it a standard choice for machinery that requires significant operational loads, such as screw compressors in refrigeration systems.

Other voltage options like 240 VAC and 600 VAC are less common for such large-scale applications, while 380 VAC is more commonly found in certain international standards. Hence, 480 VAC is the most appropriate choice for the motor voltage of a screw compressor in industrial refrigeration contexts.
