I am very new to this topic area. i am currently using the Pololu (item #: 1442) motor to simply spin up a mechnical component on a fixture and am using Labview to measure and display the component’s RPMs. I am manually increasing/decreasing voltage on a power supply in order to achieve the desired RPM value. What is the easiest way to close-loop control this motor using Labview and power supply ? Should i be incorporating Pololu’s DRV8838 Single Brushed DC Motor Driver Carrier (item #: 2990) somehow. Would i be using Labview to input the PWM into the ENABLE input on this driver PCB ? Or, can i control the power supply (programmable Rigor DP832 pwr supply) with Labview and directly interface to motor from pwr supply to automatically increase/decrease voltage to achieve a desired spin rate?
Any guidance and/or technical literature references on this topic/application would be very appreciated. i’m not sure where to start, but since i already am using the Pololu motor with its encoder, i thought it best to start here on this blog.
thank-you very much for any help!
