Some of its common problems include failure to start, motor overheating, noise, and vibration. Check the face of the brushes- it should be shiny or polished which will indicate good contact. DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. Ambient temperature too high. %PDF-1.3 %���� Look for: Broken mounting holes or feet; Darkened paint in the middle of the motor (indicating excessive heat) The DC Motor Troubleshooting Trainer, H-113. DC motor fault zone analysis is a vital part of any DC motor maintenance program. Remove the load from the motor and inspect the amp draw of the motor unloaded. 2 This review may reveal on-going problems that are both integral to the motor itself as well as external conditions (e.g., overloads, unbalances, misapplications) that are adversely affecting the motor’s normal operating condition. Troubleshooting Electric Motor Problems Made Easy for You. ����QK2R��C�m Y@ Y� �F4JR��e�z��ne�pB`]. Check the brush length.
