M Line – MAF – Low and High Voltage – TEAAC – Slip Ring
M Line motors are manufactured in different configurations in reference to cooling methods and degree of protection, allowing the machine to be designed as suitable as possible to meet operation and environment requirements.
Motors in frame sizes IEC 280 to 560 are manufactured in cast iron, while frame sizes IEC 630 and above are fabricated in welded steel plates.
