What is the difference between a low temperature servo motor and an ordinary motor?

Low-temperature servo motors and ordinary motors are two different types of motors, which have some differences in working principle, performance characteristics and application scope. In this article, the difference between low temperature servo motors and ordinary motors will be introduced in detail.
First of all, we need to understand the basic concept of low temperature servo motor and ordinary motor. Cryogenic servo motor is a kind of servo motor that can work normally in low temperature environment, it has high precision and response speed, and is suitable for precision control in low temperature environment. Ordinary motor is a kind of common electric motor, which is widely used in various industrial and civil fields.

Next, let’s explore the difference between low-temperature servo motors and ordinary motors:
Working environment: the main difference between low-temperature servo motors and ordinary motors is the working environment. Low-temperature servo motors are suitable for low-temperature environment, usually working temperature between -40 ℃ and +85 ℃. While ordinary motors are suitable for working in room temperature environment, usually the working temperature is between 0℃ and +40℃.

  • Material Selection: Because the low temperature servo motor needs to work in a low temperature environment, its material selection is different from the ordinary motor. Low-temperature servo motor materials need to have good low-temperature toughness and resistance to cold brittleness, in order to ensure that the normal work in a low-temperature environment. The material selection of ordinary motors is mainly to consider its performance and cost in room temperature environment and other factors.
  • Cooling method: the cooling method of low temperature servo motor and ordinary motor is also different. Low-temperature servo motors usually use liquid nitrogen or liquid helium and other low-temperature cooling medium for cooling to keep the temperature of the motor within the operating range. While ordinary motors are usually cooled by room temperature cooling media such as air or water.
  • Control precision: low-temperature servo motors have high control precision and response speed, which can realize precise control of the motor. While the control precision and response speed of ordinary motors are relatively low.
  • Price and maintenance cost: Because the material selection and manufacturing process of Low-temperature servo motor are more complicated, its price and maintenance cost are relatively high. While the price and maintenance cost of ordinary motors are relatively low.

In conclusion, low temperature servo motor and ordinary motor are two different types of motors, which have some differences in working principle, performance characteristics and application scope. Low-temperature servo motors are suitable for precision control in low-temperature environments, with high control accuracy and response speed; while ordinary motors are suitable for general industrial and civil applications in room temperature environments, with lower prices and maintenance costs. In actual application, we need to choose the right motor according to the specific application scenario, and use and maintain it correctly to ensure its normal work.
