1S SERVO MOTOR MAX TEMPERATURE

Class F for servos refers to the insulation class of the motor. This class indicates how well the motor insulation can withstand high temperatures and voltages. Class F insulation can withstand temperatures up to 155°C, which means that the motor can operate for a long time in a high temperature environment without the insulation being damaged

What are the Insulation Levels of Servo Motor?

Servomotor insulation class refers to the voltage withstand capability of the servomotor insulation system, also known as insulation withstand test voltage. The higher the insulation level of the servo motor, the stronger the voltage withstand capability of its insulation system, which can work under higher voltage and has higher safety and reliability.

 According to the standards of the International Electrotechnical Commission (IEC), the insulation class of servo motors is divided into five classes: A, E, B, F and H. The insulation class of servo motors is divided into five classes: A, E, B, F and H. Among them, class A is the lowest class and class H is the highest class. Servo motors of different grades are suitable for different working environments and electrical loads.

• Class A. Suitable for applications with minimum electrical load and minimum temperature rise requirements, such as some low power servo motor applications.
• Class E. Suitable for general industrial applications, with good voltage resistance and temperature rise characteristics.
• Class B. Suitable for applications requiring higher electrical loads and higher ambient temperatures, such as some medium-power servo motor applications.
• Class F. Suitable for long time operation under high temperature environment, with higher voltage resistance and lower temperature rise characteristics.
• Class H. Suitable for special occasions, such as high temperature, high altitude, high humidity and other extreme environment servo motor applications, with the highest pressure resistance and the lowest temperature rise characteristics.

Test standard for insulation class of servo motors:
The insulation level of high torque servo motors needs to be determined through rigorous testing. Common test standards include IEC60034-1, UL1446, and so on. These standards specify the method of insulation withstand voltage test, test voltage, test time, and judgment criteria of test results to ensure that the insulation system of servo motors meets the requirements of safety and reliability.
