The OMEW motor comes in two different versions. Both versions are designed mainly for propel applications, but they are optimized for different conditions. The advantage of this motor lies in the high-speed area. When the flow exceeds 40 l/min this motor is to prefer due to a lower pressure drop. The advantage of this motor lies in the low speed area. This motor has higher efficiency at low speed / medium pressure. When the flow is below 40 l/min this motor is to prefer. This motor also has the Brake nose which makes it possible to add a drum brake to the motor. Although the OMEW transmission...

Intermittent operation: the permissible values may occur for max. 10% of every minute. 2) Peak load: the permissible values may occur for max. 1% of every minute. CW version (clockwise rotation) 1. By clockwise rotation: The shaft seal pressure equals the return pressure. 2. By counterclockwise rotation: The shaft seal pressure equals the input pressure CCW version (counterclockwise rotation) 1. By counterclockwise rotation: The shaft seal pressure equals the return pressure. 2. By clockwise rotation: The shaft seal pressure equals the input pressure WHITE can accept no responsibility for possible...

Permissible shaft loads As the OMEW output shaft is embedded in needle bearings and the mounting flange is recessed it is possible to fit a wheel hub directly onto the shaft so that the radial load acts midway between the needle bearings. Based upon the requested max. speed and the point of action of the radial load the permissible shaft load can be read from the curve shown below. Curve A shows the max. radial load. If the radial load exceeds these values there is a potential risk of breakdown. The other curves apply to a B10 bearing life of 2000 hours at the indicated speed when applying a...
