*Note: The characteristics have been determined under warm
conditions at a coil temperature of 80C, a rotor temperature of 60C
and 85C electronic temperature, tested in conjunction with our
proprietary CPM controller. Due to tolerances the performance data
may deviate +/-5 % from the specified data due to production
tolerances.
