Description
The ZIEHL-ABEGG MK137-2DK.07.N (Article Number: 210027H) is a high-performance 3-phase AC external rotor motor featuring a 137 mm stator diameter. Engineered in Germany for heavy-duty industrial applications, this robust motor features a dust-sealed design with a sealing band, long-time lubricated ball bearings, thermal contact motor protection, and IP54Z ingress protection. Operating on a 3-phase nominal voltage of 400 VAC (50 Hz) or 460 VAC (60 Hz) with ±10% tolerance in a Y (Star) connection, it delivers multi-frequency performance: at 400 VAC (50 Hz), it draws a Max. Current of 1.80 A at a rated speed of 2,820 RPM with a power factor (COSφ) of 0.78 at 40 °C. At 460 VAC (60 Hz), it operates at a Max. Current of 1.80 A with a rated speed of 3,430 RPM and a COSφ of 0.83 at 40 °C. Equipped with a 6-wire supply cable (6 x 0.75 mm² x 205 cm, Li4G4G-J), a jet black finish (RAL 9005), and a Weight of 11.60 kg, it operates reliably in ambient temperatures down to -40 °C under thermal class 155 construction, holding safety approvals including CE and RoHS.
