YKK motors have a welded steel frame. They are rated from 160 to 12000 kW, and are available at 50 and 60 Hz in shaft heights from 315 to 1120 mm. The complete range is designed for fixed speed drive applications with DOL power supply, and is available for VFD cases fed by frequency converters The motors are available for horizontal or vertical mounting. Vertical mounting is specifically designed for vertical, condensate and circulating water pumps. YKK 355-1120 motor has a shaft mounted inside fan (if any) using the surrounding air for cooling. The motor is so designed that the ingress of rain, snow and airborne particles into the electrical parts is reduced. The motor is protected such that splashing water from any direction will have no harmful effect. The standard filter material is galvanized steel. IC611 / IP55 This design has an air-to-air heat exchanger mounted on the motor, which is fully enclosed.
