Efficiency Calculation

[selman]

Hello everyone,

I’m trying to calculate efficiency(based on ODrive, no Dyno).
There are some parameters in ODrive but i’m confused.

1. axis0.motor.current_control.power
2. axis0.controller.electrical_power
3. axis0.controller.mechanical_power
   and i also added this parameters
4. vbus_voltage * ibus
5. VdId+VqIq (motor.current_control.v_current_control_integral_q x motor.current_control.Iq_setpoint+motor.current_control.v_current_control_integral_d
   x motor.current_control.Id_setpoint)

What are the differences between this parameters and which are the best way for calculation of efficiency?

Thanks for help.

Some updates and results

VdqIdq=1.5*dev0.axis0.motor.current_control.v_current_control_integral_q*dev0.axis0.motor.current_control.Iq_setpoint + dev0.axis0.motor.current_control.v_current_control_integral_d*dev0.axis0.motor.current_control.Id_measured
	Ep=dev0.axis0.controller.electrical_power
	Mp=dev0.axis0.controller.mechanical_power
	VIbus=dev0.vbus_voltage*dev0.ibus
	CCp=dev0.axis0.motor.current_control.power

mechanical power shouldn’t be that low.

Also, all the other stuff is calculated from the same sensors so it won’t really be useful
