Why does my SCHABMULLER Engine overheat during operation under load?
- MMelissa MillerAug 17, 2025
There are several reasons why your SCHABMULLER Engine might overheat during operation: * Unfavorable pulse width modulation (for permanent magnet motors): If the rotor is demagnetized, replace it. Check the stator (resistance and insulation) and replace if necessary. * Overload: Reduce the load on the motor. * Blocked ventilation: Clean the ventilation openings and cooling ducts to ensure continuous airflow. * Poor connection: Check that all lines are correctly connected. * Shorted winding: The stator must be rewound. * High ambient temperature: Locate and shield the motor from the heat source, or switch it off if necessary.
