.motor running hot

1. Electrical overload caused by excessive voltage supply or overwork by drawing more current will lead to overheating issues. As the motor works harder or under unusual load, heat will be the chief byproduct, leading to failure.

2. Low resistance is the most common reason behind electric motor failure. Degradation of motor windings by heat will pave the way for short-circuits and leakages, which leave the motor at risk for failure.

3. Contamination of dust and debris will raise the internal temperature of a motor and keep it from cooling, which leads to excessive heat over a longer period of time. This generally occurs without proper maintenance or venting for particles.

• A lack of ventilation: If there is something blocking the ventilation holes for your electric motor, then hot air won’t escape and will build up within the system, causing damage. Scheduling regular maintenance on your motor can help reduce this risk.

4. Start-stop frequency plays a big role in heat damage. Excessively starting, stopping, and starting the motor again won’t allow it to cool properly. The result is a high-heat environment that wears on the integrity of components.

5. Vibration from a condition like soft foot leads to excessive heat. If vibrations are severe enough, they’ll raise temperatures to unsafe levels and stress components beyond their capacity for heat.

6. High ambient temperatures

If a motor is running in a much warmer environment than it was designed for, it can overheat because the ambient temperatures will make it more difficult for the motor to cool down properly. Check the insulation class of your motor (found on the motor’s nameplate).

7. High or low voltage supply

Power supply may be insufficient due to amp draw. In order to overcome load or inertia at a stand-still, the motor’s running current will be too much high under load. Incorrect voltage supply will make the motor work harder and could cause it to overheat.
