Electric motors are the workhorses behind countless machines in homes, businesses, and industrial facilities. Because they often run quietly in the background, it can be easy to overlook early signs of trouble. Catching problems early can help prevent breakdowns, more expensive repairs, and lost productivity. Knowing what to watch for allows you to take action before a minor issue turns into major motor failure. At Industrial Motors & Machining , we provide expert electric motor repair in the greater Denver area . Here are four common signs of an electric motor problem. Abnormal Sounds During Operation Grinding, squealing, rattling, or buzzing sounds can point to worn bearings, loose components, or electrical issues inside the motor. Bearings naturally wear over time, and when they begin to fail, they often create worrisome sounds. Ignoring these noises can potentially cause the motor to seize. Overheating Electric motors generate some heat during normal operation, but excessive heat is a warning sign that something is wrong. Overheating may be caused by overloaded circuits, poor ventilation, failing insulation, or mechanical friction. If the motor housing feels unusually hot to the touch, the motor should be inspected. Prolonged overheating can degrade internal components and significantly shorten the motor’s lifespan. Vibration/Shaking A properly functioning motor should run smoothly with minimal vibration. Noticeable shaking or vibration can indicate imbalance, misalignment, or bent shafts. Over time, persistent vibration can loosen bolts, wear down mounts, and lead to more serious mechanical issues. Addressing vibration early can help prevent more widespread equipment damage. Reduced Performance or Power Loss If equipment powered by the motor seems to be running slower, struggling under normal loads, or losing efficiency, the motor may be at fault. Electrical problems such as winding damage, voltage imbalance, or worn internal parts can reduce output power. A drop in performance may mean the motor is working harder than it should, which can cause additional stress and overheating. Monitoring performance changes helps catch issues before they worsen.
