Currently I am working on a dynamometer project for analysing PMDC motor parameter to create a laboratory setup , so how should I proceed in the selection criteria of the processor for my project ,as I have to know the speed , torque, current, temperature, and load acting on the motor ?
If the motor speed is not that high, you might find that most of the Cortex-M processors (excluding the peripherals/interface aspect) has the data processing capability for your project. However, the project you are doing to do require a number of interface/peripherals (e.g. sensors to detect motor rotation speed, ADC for current measurement, etc.). So the first step is possibly to:
- identify the peripherals that you will need for the project
- select a microcontroller product that contain the peripherals required,
- and then use a general purposed microcontroller development board to try to create each of the physical interface.
Assumed this is not for production, there are many electronic components available in online shops to help. For example:
Speed sensor: https://www.amazon.co.uk/TOOGOO-Measuring-Comparator-Sensor-Module/dp/B071G7Z2Q7
Temperature sensor: https://www.amazon.co.uk/Waterproof-DS18B20-Temperature-Digital-Thermal/dp/B01C2I9SQE/
Current sensor : ADC (inside microcontroller) with shunt resistor
