TMS320F280039C: InstaSPIN power internal power calculation

Krzysztof Golda

Part Number: TMS320F280039C

Hello,

Is in InstaSPIN software (I based on universal_motorcontrol_lab) an already made method which computes input and/or output power of motor?

Best Regards,

Hi Krzysztof,

Our universal motor control lab expert is out of office until Monday, please expect a response back early next week.

Thank you,

Luke

Only the output power calculation is in Universal lab. The input power can't be calculated directly, you have to add the current sensing circuit accordingly. And the calculation power is not related to the motor control algorithm, that could be used for InstaSPIN as well.

In the motor_common.c source file in line 757 there is power calculation, and comment suggest it is reagrding input power.

Yes, it's the input power of the motor that's equal to the output power of the inverter, not the input power of the inverter.
