Notes: All current ratings are rms values per motor phase. Internal algorithms automatically reduce maximum current limit when
heatsink temperature is >85°C or battery voltage is outside the allowed limits. Heatsink temperature is measured internally
near the power MOSFETs.
The 2-minute rating is based on an initial controller heatsink temperature of 25°C and a maximum heatsink temperature
of 85°C. No additional external heatsink is used for the 2-minute rating test.
Operation at or below the continuous rating is required to achieve the lifetime rating.
Ratings are based on the more conservative result of an airflow test and a power capacitor lifetime calculation. For the airflow test,
the controller is mounted on a 6mm thick square steel plate (0.25m 2 ) in a 6km/hr airflow at 25°C temperature. Rated current is when
the controller baseplate temperature reaches 85°C (thermal cutback). The capacitor lifetime calculation assumes internal controller
temperature = 70°C (same as baseplate temperature), modulation index = 60%, and power factor = 0.866.
