Liquid Cooled Motors

 Liquid-cooled servo motors is a type of servo motor that uses a liquid (typically water or coolant) as a cooling medium. Its key advantage lies in its extremely high heat dissipation efficiency, which allows it to achieve significantly higher power output than air-cooled motors within the same installation space.

Design Standards:

Design standards for air-cooled servo motors primarily cover several areas, including basic general standards, cooling method standards, specialized standards, and energy efficiency standards. Together, these standards define key design requirements for motor performance, safety, and cooling methods.

Liquid-cooled servo motors can be classified in various ways, based on the following criteria:
Classification by Cooling Medium
Water-cooled: The most common type, which uses water or a water-based coolant. Water has a high specific heat capacity, provides excellent heat dissipation, and is relatively low-cost.
Oil-cooled: Uses specialized cooling oil. Oil offers better insulation and rust protection, making it suitable for certain specialized environments, but its thermal conductivity is generally slightly inferior to that of water.
Liquid-cooled servo motors Name How It Works Features
Water-cooled Since water is not an insulator, water-cooled servo motors generally use an indirect cooling method. The coolant circulates within the water jacket (or cooling jacket) of the motor housing and does not come into direct contact with the internal windings or permanent magnets. Extremely high heat dissipation efficiency

Significant power boost

Good temperature uniformity
Oil-cooled Oil cooling uses mineral oil or synthetic oil as the cooling medium; its most notable feature is its excellent insulating properties, which allow the oil to flow directly into the motor for cooling. Can come into direct contact with heat sources

Excellent cooling performance

High adaptability to various environments


 

Liquid Cooled Motors Features

   Excellent Heat Dissipation: The thermal conductivity and specific heat capacity of liquids are far higher than those of air, resulting in low temperature rise and rapid heat dissipation.

High Power Density: Delivers greater power and torque per unit volume, with power output increases of up to 50% or more.

High Overload Capacity: Features high short-term peak torque and stall torque, making it suitable for heavy loads and frequent start-stop cycles.

Compact Design: Requires no fans or heat sinks, resulting in a small footprint that facilitates equipment integration.

Excellent Protection: Typically rated IP65 or higher, resistant to dust, oil, and moisture.

Low Noise and Maintenance-Free: No cooling fan means low noise, minimal maintenance, and a long service life.

Stable Precision: Uniform temperature distribution and minimal thermal deformation help maintain positioning accuracy.

Wide Environmental Adaptability: Water cooling is highly efficient and economical, while oil cooling provides insulation and withstands harsh environments.

Air Cooled Electric Motors FAQ

  • Q How do I choose between air cooling and liquid cooling (water cooling)?

    A
    Air cooling: Simple design, lower cost, and easy maintenance, but with limited heat dissipation capacity; fans may also generate noise.
    Liquid cooling: Extremely high heat dissipation efficiency, enabling higher power and torque for the same volume, but the system is complex, costly, and carries a risk of fluid leaks.
    Recommendation: Prioritize air cooling; if air cooling cannot meet heat dissipation requirements (such as extremely high power density requirements), then consider liquid cooling.

  • Q Why is air cooling necessary?

    A During operation, servo motors generate heat due to copper losses, iron losses, and mechanical friction. If heat builds up, it can lead to problems such as insulation aging and demagnetization of the permanent magnets. Forced air cooling effectively controls temperature rise and ensures stable motor operation.

  • Q What is an air-cooled servo motor?

    A
    Air-cooled servo motors are servo motors that rely on airflow to dissipate heat from inside the motor. They are typically classified into two types:
    Natural cooling (convection cooling): Heat is dissipated naturally through the heat sinks on the motor housing; this is suitable for applications with lower power requirements or intermittent operation.
    Forced air cooling (fan cooling): The motor is equipped with a separate fan at the rear or side, which significantly improves heat dissipation efficiency through forced convection.
