hi everyone, I am an engineer in Singapore. I have come to a question that required the formula of calculating the energy consumption of ECM. Can my engineer bodies please give me a hand?

Can you monitor the electrical power draw of the motor? If the know the voltage and current, you can calculate power consumption, which seems to me would be the most straightforward method.

Or if you know the load and the efficiency you can calculate the power input needed.
