# Power consumption for an in-wheel motor

I'm trying to estimate the power consumption of an in-wheel electric motor. I used the formula

$$P = T\cdot\omega + K_m\cdot T^2$$

where T is the torque, ω is the motor angular velocity and $$\K_m\$$ is a constant who takes into account power electronics and motor copper losses. I plotted the power over time.

Is this the right way to calculate the power consumption? How can I treat this topic in a not too detailed but exhaustive way?

All the best.

• "not too detailed" and "exhaustive" seem mutually contradictory to me. Which do you want? – Dave Tweed Dec 6 '18 at 13:15
• @DaveTweed exhaustive is good – Manuel Dec 6 '18 at 13:35
• Normally, the motor constant Km applies to copper losses in the motor only. – user28910 Dec 6 '18 at 14:58
