Two motor sizes (2.2kW and 3kW) were fitted to extruders on production lines as part of a programme to reduce engineering costs. They replaced modified normal-style finned motors.
The application is particularly demanding. The motors, which drive a rotating knife, have to operate in a hot and steamy environment where they can gather cereal, which calls for high pressure hose wash-down.
The original, standard motors used had a survival expectation of between 30 to 40 days before failure. The two Marlin stainless motors have been working continuously without failure for 230 days and 364 respectively. They have saved £4,250 on the original motors and against the modified motors they have saved £1,750.
