Provide quick and accurate measurements
Where we strive to provide you with innovative and user-friendly tools for various applications. We present the Motor Subcooling Calculator, a powerful tool designed to help you determine the subcooling requirements for electric motors. Proper subcooling is essential for maintaining optimal motor performance and preventing overheating. With our calculator, you can easily assess and adjust the cooling system to ensure efficient operation and prolong the lifespan of your motors.
Understanding Motor Subcooling:
Electric motors generate heat during operation, and effective cooling is necessary to maintain their temperature within safe limits. Subcooling refers to the temperature difference between the cooling medium (e.g., air or liquid) and the motor winding temperature. It acts as a buffer, preventing the motor from reaching its thermal limits and enhancing its overall performance.

Formula for Calculating Subcooling
The formula for calculating subcooling varies depending on the cooling medium (air or liquid) used. Here are the formulas for both scenarios:
Subcooling Calculation for Air Cooling:
Subcooling (ΔTsub) = Winding Temperature (Tw) – Ambient Temperature (Ta)
Where:
- ΔTsub is the subcooling temperature in degrees Celsius or Fahrenheit.
- Tw is the motor winding temperature in degrees Celsius or Fahrenheit.
- Ta is the ambient temperature in degrees Celsius or Fahrenheit.
Subcooling Calculation for Liquid Cooling:
Subcooling (ΔTsub) = Liquid Temperature (Tl) – Winding Temperature (Tw)
Where:
- ΔTsub is the subcooling temperature in degrees Celsius or Fahrenheit.
- Tl is the temperature of the cooling liquid in degrees Celsius or Fahrenheit.
- Tw is the motor winding temperature in degrees Celsius or Fahrenheit.
Note: Ensure that the temperatures used in the calculation are in the same unit (either Celsius or Fahrenheit) to obtain accurate
Determining subcooling requirements
Motor Specifications:
- Enter the rated power of the motor (in kilowatts or horsepower).
- Provide the motor’s voltage and current ratings.
- Specify the type of cooling system employed (air or liquid).
Cooling System Details:
- Input the ambient temperature of the environment in which the motor operates.
- Specify the temperature of the cooling medium (air or liquid) used for cooling the motor.
Subcooling Calculation:
- Once all the relevant information is provided, the Motor Subcooling Calculator automatically computes the subcooling requirement for the motor.
