8. Others

    8-1 Whatever items which be not stated in this specification will be not guaranteed.

    8-2 Do not subject the motor under locked condition for long times.

    8-3 Reflow Temperature : 250˚CMax
            Exceeding this temperature will result in shorting and dead spot failures.
            Excessive heat weakens the magnets and it is also possible that the coating
            on the magnet wires melts causing a short in the motor.

8-4 Output test date and Cpk will be attached (n-35) of follows:
           Loaded rotation                             rpm
           Loaded current                              mA
           Lock current (Starting Current)         mA
           Starting voltage V (without consideration of Cpk value)
