Proteus Speed and rpm measuring

[voyager2]

I am working on a Proteus circuit in which I am operating a 3 phase motor however I trying to take measure the speed and rpm and don't know how. There is no tachometer component I can use and I've tried setting up some sort of encoder with no success. The signals are generated from pwm pins on an Arduino. If anyone Anyone has any ideas to help it would be appreciated.

In the directory C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\SAMPLES\Graph Based Simulation you find "Induction 3-phase motor.pdsprj" file that shows how to get rpm and speed information.
