Description

Torque reaches 16 000 N·m at 350–1500 rpm, with 4–16 poles and frames 132–450. The housing is grey cast iron or, on request, steel, and the shaft has one or two ends, tapered or cylindrical. Mounting is B3, B5, B35 and V1, cooling IC411 or IC416, protection degree IP55. The strong mechanical design withstands shock loads, a high pull-out torque gives starting under full load even with voltage fluctuations, and overload capability reaches 150 %. As standard the motors are designed for temperatures up to 40 °C, optionally up to 80 °C. Copies of old motors are also available, for example for 550 V with exactly reproduced mounting dimensions.

How to choose

The duty type to IEC 60034-1 and EN 60034-1 (S2, S3 or S4) and the number of starts determine the motor design. For metallurgical and smelting plants with dust and slag, and for ports with salty air and strong wind, special versions are made, including marine ones fully protected from moisture. In place of the MTN, MTF, MTKN and 4MT series, motors to customer requirements or exact mechanical and electrical copies are fitted, extending crane service without rework. Modernisation with better drive dynamics and lower no-load consumption is also available.
