Description
MEBKSL is a modular series of three-phase squirrel-cage induction motors in enclosed design with an air-to-air heat exchanger for low, medium and high voltage. The motors have a compact design but very high output. The manufacturer positions them for heavy industrial applications, for example drives of crushers and fans at cement plants.
Cooling is arranged as IC611 (shaft-mounted fans), IC616 (external circuit with an independent fan) or IC666 (both circuits with independent fans). The internal air circulates in a closed circuit through a tubular heat exchanger, and the external air does not enter the machine. Therefore no cooling water is needed, and the active parts are protected from dust. The heat exchanger is usually of welded construction with steel or aluminium tubes.
Main parameters: voltage from 380 V to 13.8 kV, output up to 20 MW, shaft height up to 900 mm (frame sizes 315–900), degree of protection IP23 or IP55. For medium and high voltage the standard values lie within 3–11 kV at 50 Hz and 2.3–13.8 kV at 60 Hz. The frame is welded steel with integrated bearing plates, which gives good cooling and high torsional rigidity. Terminal boxes are placed on the left and/or right. Insulation is class F with temperature rise to class B. Mounting arrangements are IM B3 and IM V1, while special designs and non-standard connection dimensions are made on request. The motors are intended for supply from the mains and from a frequency converter.
The basic design of the MEBKSL, MEBKSW and MEBKSD motors is practically the same, while the cooling systems, degrees of protection and mounting arrangements vary. This speeds up manufacture and allows the motor to be adapted quickly to the industrial task. Before shipment every motor is tested on the manufacturer's own test field (up to 2300 kVA, 400–13,800 V, up to 120 Hz). Typical applications are crushers, mills and fans in the cement and mining industries, compressors in the chemical and oil and gas industries, and pumps in power plants and water utilities. Completed projects include a 690 V motor for a mill with ATEX certification and a standby 690 V motor for four sugar factories.

Questions and answers
What cooling arrangements does MEBKSL have?
There are three arrangements. IC611 has shaft-mounted fans, IC616 has an external circuit with an independent fan, and IC666 has independent fans in both circuits. No cooling water is needed.
What voltage and output range does the MEBKSL series have?
Voltage from 380 V to 13.8 kV, output up to 20 MW, shaft height up to 900 mm (frame sizes 315–900).
What degree of protection do the motors have and what tests do they undergo?
The degree of protection is IP23 or IP55. Before shipment every motor is tested on the manufacturer's test field, up to 2300 kVA, 400–13,800 V, up to 120 Hz.
