General Specifications
| Item | Specifications |
|---|---|
| Insulation Resistance | After rated operation at normal ambient temperature and humidity, the measurement between the coils and the case is 100 MΩ min. using a 500 VDC megger. |
| Dielectric Strength | After continuous rated operation at normal ambient temperature and humidity, no abnormalities were observed even with an application of 1.5 kV at 50 Hz or 60 Hz between the coils and the case for 1 minute. |
| Temperature Rise | After a gearhead or equivalent heat sink*is connected for rated operation at normal ambient temperature and humidity, the measurement value of the winding temperature rise is 70 °C max. using the resistance change method. |
