The cooling method for YY-H series single-phase capacitor operated marine asynchronous motors is IC0041 for machine bases 56 and below, IC01 41 for machine bases 63 and above, and IP44 for external protection level. This series uses 8-level insulation materials, and the windings have good insulation and mechanical strength. The junction box is mounted on the top of the motor for easy wiring in all four directions.

The YY-H series single-phase capacitor operated marine asynchronous motor has the following four basic types of installation methods
1. B3 type - The machine base has feet and the end cover has no flange
2. B34 type - the machine base has feet, the end cover has a small flange, and the shaft extends at the flange end;
3. Bl4 type - the machine base has no feet, and there is a small flange on the end cover, with the shaft extending from the flange end;
4. B5 type - The machine base has no feet, and there is a large flange on the end cover, with the shaft extending from the flange end.
