Need Suggestions to Control the Position of an AC Motor Using an Inverter

Click For Summary
SUMMARY

The discussion centers on controlling the position of an AC motor using the Altivar 16 Square D inverter. The user seeks advice on suitable sensors, specifically considering a rotary encoder for position feedback. Additionally, concerns about torque management during sudden direction changes of the motor are raised. The suggestion to explore Servo Motors as an alternative is also presented.

Hi, I'm new in this forum. Nice to meet you all.

I'm currently working on a project that uses AC motor. The goal is to make a position control system for the motor. Currently I'm using the Altivar 16 Square D inverter to control the speed of the motor. It uses a logic voltage to control the directoin of the AC motor and a DC voltage as the input and gives an AC voltage with a corresponding frequency that will be feeded to the motor to achieve a certain speed.

What becomes my concern is what sensors should I use? I'm thinking of a rotary encoder, but is it enough? And I'm also concerned about the torque, is it okay if I suddenly change the direction of the motor? How to calculate or check this?

Thanks for the help. :smile:

It sounds like you should be looking into Servo Motors instead, no? :smile:
