Y / YKS / YKK High Voltage Motor


The three series use different cooling arrangements. Y motors use open-circuit air cooling, YKS motors use an air-to-water heat exchanger, and YKK motors use an air-to-air heat exchanger. Enclosure protection depends on the selected series and configuration.
Select the motor according to the required output, speed, starting conditions, driven-load inertia and cooling facilities. Standard mounting is IM B3, with other arrangements subject to confirmation.
Before installation or replacement, verify the electrical ratings, shaft dimensions, foundation interfaces, overall size and maintenance space using the model-specific documentation.ration.

Provide the required power, voltage, frequency, speed, mounting arrangement and operating duty. Include the driven-load torque, inertia, starting method, site conditions and available cooling facilities.
Y motors use open-circuit air cooling. YKS motors use an air-to-water heat exchanger, while YKK motors use an air-to-air heat exchanger. Their enclosure protection and installation requirements differ.
Yes. The air-to-water heat exchanger requires a suitable cooling-water supply. Confirm the required flow, inlet temperature, pressure and water quality for the selected motor.
Its catalog-listed air-to-air cooling arrangement does not require cooling water for the heat exchanger. Adequate airflow and clearance around the motor must still be provided.
The catalog mentions alternative-voltage versions. Submit the required voltage and frequency for confirmation of availability, ratings and dimensions.
