In the use of DC motors, it is crucial to operate them properly. However, even if the equipment passes quality checks, improper usage can lead to malfunctions. Let's take a common issue as an example: what should you do if the device overheats beyond the temperature rise standard or starts smoking after startup? Today, we'll provide you with the solution. Read on in the following article.

Reason:

(1) Low power voltage resulted in excessive temperature rise under the rated load for the machinery.

(2) Poor equipment ventilation or excessively high humidity levels.

Equipment overload or single-phase operation.

(4) Frequent mechanical startups or excessive forward/reverse cycles.

Stator and rotor friction.

Approach to Handling:

(1) Measure no-load and loaded voltages.

Inspect motor fans and clean ventilation ducts to enhance ventilation and reduce ambient temperature.

After checking the phase currents with a clamp meter, address the issues accordingly.

(4) Reduce the number of forward and reverse cycles of the equipment, or replace it with a model suitable for frequent startups and forward/reverse operations.

Direct current (DC) motor overheating or smoking and repair methods are now at your fingertips. In the future, when everyone encounters this situation, you won't be at a loss. By identifying the cause of the fault and then "treating the root of the problem," you can resolve the issue promptly, thus avoiding disruption to the work process and unnecessary trouble.
