Electric Motor Heat Loss Formula
The following two example problems outline the steps and information needed to calculate the Electric Motor Heat Loss.
EMHL = S * (1-E/100) * 3412.142
Variables:
- EMHL is the Electric Motor Heat Loss (Btu/hr)
- S is the size of the motor (kW)
- E is the efficiency of the electric motor (%)
To calculate electric motor heat loss, subtract the efficiency ratio from 1, multiply by the size of the motor, then again by 3412.142.
How to Calculate Electric Motor Heat Loss?
The following steps outline how to calculate the Electric Motor Heat Loss.
- First, determine the size of the motor (kW).
- Next, determine the efficiency of the electric motor (%).
- Next, gather the formula from above = EMHL = S * (1-E/100) * 3412.142.
- Finally, calculate the Electric Motor Heat Loss.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
size of the motor (kW) = 100
efficiency of the electric motor (%) = 50
EMHL = S * (1-E/100) * 3412.142 = ?
