Conformance to
standards
AC motors and AC brake motors from SEW-EURODRIVE conform to the relevant
standards and regulations, in particular:
• IEC 60034-1, EN 60034-1
Rotating electrical machinery, rating and performance.
• EN 60529
IP degrees of protection provided by enclosures of electrical equipment.
• IEC 60072
Dimensions and performance of rotating electrical machinery.
• EN 50262
Metric threads of cable glands.
• EN 50347
Standardized dimensions and power ratings.
Rated data The specific data of an asynchronous AC motor (AC squirrel cage motor) are:
•Size
• Rated power
• Cyclic duration factor
• Rated speed
• Rated current
• Rated voltage
• Power factor cosϕ
•Enclosure
• Thermal classification
• Efficiency class
This data is given on the nameplate of the motor. In accordance with IEC 60034
(EN 60034), the nameplate data apply to a maximum ambient temperature of 40 °C (104
°F) and a maximum altitude of 1000 m (3300 ft) above sea level.
