  Tiffany AndersonAug 12, 2025
  The operating temperature of the Stober Engine might be too high due to several reasons. The speed or torque could be too high, requiring a check of the gear unit's design. The motor might be heating the gear unit excessively, in which case you should ensure sufficient motor cooling. Also, check the motor wiring. If the surrounding temperature is too high, provide sufficient cooling for the gear unit. In some cases, the motor should be replaced. If the issue persists, it may be due to bearing damage.
