Induction Motors, 1PH7 (APH7S) – 05.04 Edition
Ambient/cooling medium temperature
Operation: T = –15 °C to +40 °C (without any restrictions)
Bearing design: T = –20 °C to +70 °C
All of the Catalog data refer to an ambient temperature of 40 °C, mounted so that
the motors are not thermally insulated and an installation altitude up to 1000 m
above sea level.
If the ambient conditions differ (ambient temperature > 40 °C or the installation alti-
tude > 1000 m above sea level), the permissible torques and power ratings must
be reduced (refer to the factors from Table 1-5).
Ambient temperatures and installation altitudes are rounded-off to 5 °C or 500 m.
Table 1-5 Factors for reducing the torque/power acc. to EN 60034-6
