Under normal room temperature conditions, the operating temperature range of the motor is usually between 70 and 90 degrees Celsius.

2. Motor heating is a normal phenomenon, as long as the temperature does not exceed the rated value, it will not cause any problems.

The acceptable temperature level of a motor depends on the grade of its internal insulation material. Usually, insulation materials can withstand temperatures up to 130 degrees Celsius, which means that as long as the surface temperature of the motor does not exceed this value, the motor should not be damaged.

Therefore, the surface temperature of the motor between 70 and 80 degrees Celsius is generally considered a normal range.

5. Basic temperature measurement methods include using a thermometer for precise measurement, or using touch to preliminarily determine temperature: if touched continuously for 1 to 2 seconds, the temperature is approximately below 60 degrees Celsius; If only touched, the temperature may be between 70 and 80 degrees Celsius; If the dripping water evaporates rapidly, the temperature may be above 90 degrees Celsius.

Of course, using a professional thermometer can obtain more accurate readings.

To avoid motor overheating, the following points should be noted:

a. Ensure that the selected motor size is suitable for its application environment and working cycle, as motors that are too small may not effectively dissipate heat.

b. Pay attention to the ambient temperature, as higher temperatures can hinder the normal heat dissipation of the motor.

c. Avoid prolonged continuous operation or intermittent load operation of the motor, and ensure that the motor has sufficient time to cool between cycles.

d. Maintain the correct voltage level, as incorrect voltage can cause the motor to overheat.

e. When using motors in high-altitude areas, it is necessary to ensure that the motors have the corresponding rated values to adapt to thin air.

f. Keep the ventilation holes of the motor unobstructed to avoid blockage.

According to the operating principle of servo motors, reducing motor heat generation can be achieved by reducing copper and iron losses. This may mean selecting motors with lower rated currents and considering using series motors instead of parallel motors when selecting, although this may conflict with the required torque and speed requirements.
