Motors for use on a frequency converter

Product catalog summary

Overview: The document discusses motors with enhanced winding insulation designed for use with inverters without filters. These motors are suitable for variable speed drives operating at mains voltages over 420 V and are developed to withstand high voltage peaks.

Specifications: The motors are designed according to DIN IEC 60034-25 standards. They can operate on inverters up to 500 V (Curve A) and 690 V (Curve B) without filters. The motors use high-quality insulation materials to handle pulse voltages effectively.

Design Series:

KU Series: Suitable for 500 V inverters without filters, featuring insulated bearings from IEC size 315 and adapted PTC thermistor insulation.
KV Series: Suitable for 690 V inverters without filters, designed with high-quality insulation materials for pulse voltages.

Technical Details:

Type of protection: IP 55 according to DIN EN 60034-5, with higher protection options available.
Type of construction: IM B3, IM B35, IM B5, IM B14, IM B34, and derived types according to EN 60034-7.
Duty type: S8, S9 according to IEC 60034-1.
Type of cooling: IC 411 (K..R) or IC 416 (K..F) according to DIN EN 60034-6.

Performance: The document provides a detailed table of motor sizes, rated output power (kW), and types of cooling for both KU and KV series motors, indicating their suitability for various pole configurations and RPMs.

Applications: These motors are robust and have high withstand voltages, making them suitable for a broad range of applications in variable speed drives.

Additional Information: For further technical details, the document refers to catalogues available in printed or digital formats.
