Cool running, super-clean stainless steel motors
14 December 2014
Marathon Electric has enhanced its ranges of stainless steel, washdown heavy-duty motors for applications requiring clean or hygienic facilities, such as food processing.
Made from top quality stainless steel, the motor construction is IEC compliant, so can be easily swapped with existing cast iron motors. Protected to IP66, they offer exceptional resistance against water penetration, with three layers of defence – a shaft seal, a long ingress path and an internal slinger mechanism.
The outer surface of the motors is clean-lined, to avoid crevices and corners where dirt or grease could collect and thereby compromise cleanliness. The totally enclosed, non-ventilated (TENV) design makes them suitable for hose down and pressure washing. They are also suitable for hot water (80°C) jet washing.
The ball bearings are lubricated for life, which reduces maintenance and also helps ensure clean operation.
In terms of energy efficiency, the Marathon stainless steel motor range is fully ErP (energy-related product) compliant and meets Efficiency Class IE3. This efficient operation is a result of a design that guarantees low electrical losses in operation, which in turn means low heat emissions and compliance with food industry requirements for cool running.
The motors are available in a range of sizes and powers, and all sizes are fitted with a conventional six-pin terminal block and are suitable for use with an inverter drive for variable speed operation.
