MKG / MKP — low-voltage finned and air-cooled induction motors 55–1600 kW (including smoke extraction)
Country: Austria · Model: MKG / MKP
MKG and MKP are three-phase low-voltage squirrel-cage induction motors of 55–1600 kW, with a voltage up to 1 kV and a rotational speed up to 3600 rpm. Air cools them through the frame. MKP is designed for smoke extraction fans that work in a flow of hot gases.

Description
MKG has a finned self-ventilated frame (IC411, TEFC), IEC frame sizes 200–560 and power ratings of 55–1600 kW. The mounting versions are IM B3 (IM1001), IM B5 (IM3001), IM V1 (IM3011) and special ones on request, with protection up to IP55 and class H insulation. MKP has no fan of its own and is cooled by an air flow from the driven fan (IC418, TEAO), with frame sizes 315–560, power 100–1500 kW and IM B5 and IM V1 versions. For smoke extraction it meets the temperature classes of EN 12101-3 up to 400 °C for 2 hours, and the absence of a fan makes it easier to build into the housing of an axial fan. Direct starting, soft starting and a frequency converter are allowed. The motors are made to IEC 60034 or NEMA MG1, and MKG has special ATEX, IECEx, marine and nuclear power plant versions; the nuclear overview for MKG/HKG states up to 2500 kW, up to 13.8 kV and frame sizes 250–630 (the high-voltage HKG is a separate item).
How to choose
If you need self-ventilation and power up to 1600 kW, MKG with an IC411 frame is used. For a smoke extraction fan, where the motor sits in the hot flow, you need MKP per EN 12101-3. Both series replace large 0.4–0.69 kV motors of the 5AM and AIR types. For water cooling, look at MKH motors with a water jacket up to 2000–2500 kW of class IE4.

FAQ
How does MKG differ from MKP?
MKG has its own self-ventilation (IC411, TEFC), while MKP is cooled by an air flow from the driven fan (IC418, TEAO).
What is the power range of MKG and MKP?
MKG covers 55–1600 kW, MKP 100–1500 kW. They are installed in pumps, fans, compressors and mills.
Is MKP suitable for smoke extraction?
Yes, the design meets the temperature classes of EN 12101-3 up to 400 °C for 2 hours for operation in hot gases during a fire.
Can the motor be started from a frequency converter?
Yes, direct starting, soft starting and a frequency converter are allowed, with a rotational speed up to 3600 rpm.
Which mounting versions are available?
For MKG IM B3, IM B5 and IM V1, for MKP IM B5 and IM V1. Protection up to IP55, class H insulation.
