What is the Thermal Model of a Motor ?
Thermal Model Definition
A thermal model of a motor is defined as a simplified representation to calculate heat generation and dissipation in a motor.
Heat Generation (p1)
This is the amount of heat produced inside the motor, measured in watts.
Heat Dissipation (p2)
Heat is transferred to the cooling medium, also measured in watts.
First Order Differential Equation
This equation calculates temperature rise over time, helping predict motor heating and cooling.
Heating and Cooling Curve
This curve shows how the motor’s temperature changes during operation, crucial for understanding thermal behavior.
