Inquiry Regarding Implementing Motor Current Analysis Using ADS1115 and Revolution Pi

Post by yamaivanrooij »

Dear readers,

I am currently working on a project that involves motor current analysis of a 3.5 amp, two-phase motor, utilizing a Hall sensor for current measurement. To achieve accurate analysis, it is essential to obtain a high sample rate, specifically between 4000 to 8000 samples per minute. My analysis requires sampling for 10 seconds at both motor startup and upon reaching a steady state.

Upon researching, I found that the Revolution Pi platform may not support the desired sample rate for my application. As an alternative, I am considering the use of an ADS1115 ADC module from Joy-It, which I believe could meet my sampling rate requirements through its precision and capabilities.

However, before proceeding, I would like to gather insights and feedback from the community:

1. Has anyone successfully used an ADS1115 for similar applications, particularly for motor current analysis with high sampling rates?
2. What are the challenges and considerations in integrating the ADS1115 with a Hall sensor for current measurement in terms of hardware setup and data accuracy?
3. Can the ADS1115 support the required sampling rate for this application, and how can it be configured to optimize data collection?
4. Is the data transfer speed between the ADS and revolution PI good enough for this project to do data collecting?

I appreciate any advice or experiences you can share, including potential pitfalls, alternative solutions, or confirmation of the ADS1115's and Revolution Pi's suitability for this application.

Thank you in advance for your assistance and guidance.

Best regards,

Hi yamaivanrooij, there is a hidden champion in the Revolution Pi family is the Revolution Pi Compact module.

It is the module that has the shortest cycle time in terms of access to the inputs and outputs, as it is "compact" and not modular.
Take another look at whether this performance is sufficient for you:

It is also best to take a look at the data sheet to check whether the number of inputs and outputs is sufficient to implement your application:
