Description
Open ventilation IC01 with a shaft-mounted fan, or IC06 with an independent fan for operation from a frequency converter, gives high power density in a compact frame. The number of poles is 2, 4, 6, 8 or 10, supplied from the grid or a converter. Insulation is class 155 (F) used to class 130 (B), or class 180 (H) used to 155 (F). Mounting versions are B3, B35, B5, V1, V3, V5, V6 and others, with CE marking. For IP23 motors an operating manual is issued in many languages, covering installation, alignment, connection, lubrication and bearing replacement. The manufacturer has made electrical machines since 1882 and has belonged to a larger group since 2011. It has its own repair shop with crane equipment of 80 t capacity, and rewinds and modernises low-voltage machines.
How to choose
Compressors, pumps, fans, blowers and mills in mechanical engineering, power generation, water management and chemicals work with this series while the air is clean. In dust or moisture take enclosed motors, for example KA2 with protection degrees IP55–IP66, and for explosive zones WEX3. The series replaces protected-type motors 4AN, AN and 5AN.

FAQ
What power and shaft height do KN motors have?
Power 37–1300 kW at shaft height 250–400, voltage 200–690 V from the grid or a frequency converter.
How do cooling schemes IC01 and IC06 differ?
IC01 has a shaft-mounted fan. IC06 provides an independent fan, which is needed for operation from a frequency converter.
What efficiency classes and numbers of poles are available?
Classes IE2 and IE3, and the number of poles is 2, 4, 6, 8 or 10.
Is an IP23 motor suitable for a dusty workshop?
No, the open design is intended for fairly clean ambient air. For heavy conditions enclosed series are chosen.
What mounting versions are provided?
B3, B35, B5, V1, V3, V5, V6 and others. CE marking.
