Standard motor, design for direct or partial winding start

Designation on the name plate

Compressors with this marking are suitable for direct or partial winding start. The motor winding is

subdivided into two parts:

Part winding 1 = 50% and part winding 2 = 50%.

This winding division reduces the start-up current needed for a part winding start to approx. 50% of

that for a direct start.
