Stainless steel gearmotor meets extreme washdown rating for food use

Olsen Engineering : 27 August, 2013  (New Product)
Olsen Engineering UK has launched the Bison SaniMotor range of stainless steel gearmotors that meets the IP69K extreme washdown rating. Following successful implementation in the US, SaniMotor has aroused interest in the international OEM food packaging industry from as far afield as Dubai.
Stainless steel gearmotor meets extreme washdown rating for food use
SaniMotor gearmotors are designed to meet the IP69K extreme washdown rating established by the European IEC for equipment exposed to temperature extremes, constantly wet environments, and the use of harsh cleaning agents. Electrical components are encapsulated in thermally conductive epoxy resin, allowing use at up to 40C ambient temperature and - with derating - higher temperatures. SaniMotor features a smooth outer exterior, encased in 304 grade stainless steel to ensure clean, hygienic food processing while enduring moisture, heat and harsh cleaning solvents.
Encapsulation optimises heat conduction within the motor, allowing totally enclosed non-ventilated (TENV) operation, VSD / Inverter compatible based on a 10:1 turndown ratio for constant operation. Output shaft sealing is achieved with a two part rotor-stator style seal, providing three sealing surfaces. Electrical termination is provided by an IP69K rated stainless steel, modular, multi-pin power connector. The gear motors can be mounted in an orientation and have high side load ratings, fully tested.
The three-phase 230V inverter-duty SaniMotor range employs Bison’s Verdant Duty design for increased energy efficiency. It is available in two frame sizes; 88.4 and 127mm, each of which is mated to seven standard gearing packages, offering fixed output speeds from 345 to 8rpm at rated torque from 0.8 to 56.5Nm. 
“SaniMotor is ideally suited for food, chemical, medical and pharmaceutical processing applications,” explained Piers Olsen of Olsen Engineering UK. “It also finds a home in food service equipment, packaging machinery, factory automation, conveying, car washing and a wide variety of demanding applications where gearmotors are exposed to harsh environments or frequent washdowns.”
The SaniMotor has had proven success in the US at Eaglestone, a custom conveyor and equipment manufacturer specialising in food processing and packaging machinery. With the intention of reducing the accumulation of food borne bacteria, Eaglestone designed a new stainless steel conveyor for baked and frozen goods, incorporating the SaniMotor .
Once installed, the SaniMotor performed well in the harsh environment created by the washdown process and provided reliable operation of the transfer conveyor without any maintenance issues. Units are sealed for life with H1 food grade grease.
“We chose SaniMotor for its ability to stand up to the conditions of an extreme wash-down environment, and Bison exceeded our expectations,” explained Carmen Sammauro, Eaglestone’s President.
