How to Use Electric Motor Heat Loss Calculator
To calculate electric motor heat loss, follow these steps:
- Input Motor Size (kW): Enter the size of the electric motor in kilowatts (kW).
- Input Motor Efficiency (%): Input the efficiency of the electric motor in percentage.
- Calculate: Click the “Calculate” button to get the Electric Motor Heat Loss in Btu/hr.
Formula
The formula for calculating Electric Motor Heat Loss is as follows: EMHL = S * (1 – E/100) * 3412.142 Where:
- EMHL = Electric Motor Heat Loss (Btu/hr)
- S = Motor Size (kW)
- E = Efficiency of the electric motor (%)
Example
Let’s say you have an electric motor with a size of 5 kW and an efficiency of 85%. To calculate the heat loss: EMHL = 5 * (1 – 85/100) * 3412.142 EMHL = 5 * 0.15 * 3412.142 EMHL ≈ 25681.0657 Btu/hr
