# Health index / performance curve of a motor

I am collecting daily data of motors that consists of vibration in three direction x,y,z , RPM, Temperature, kVAh, kWh, kVArh, average voltage (LL), average voltage (LN), average PF, average current and frequency.

I am supposed to plot a health curve/Performance curve of this motor using the given parameters like this.(an example how the health curve should be.

May I know what parameters are important to plot performance curve of motor? I know speed, temperature, vibration, kWh are to be considered. But i have no idea how to use these parameters to state a performance of motor.

Here are some calculations to find out torque and plotting speed-torque curve, temperature- current, temperature- voltage.

How do i use all these plots, curves to depict a health index of motor?

Thank you.

• The picture seems more an introduction commercial for the economists. Not based upon any EE knowledge. The next slide is probably BUY something. – Marko Buršič Aug 28 '17 at 6:26
• That was just an example to plot. I would like to know how to use these parameters to make a performance curve of a motor.
