Hi, I’m designing my final year project for electrical engineering and i need to select the correct motor. I’ve narrowed my options to a dc motor or a stepper motor with roughly minimum 1Nm of torque and ideally 12V operating voltage. RPM isn’t too important as the project is proof in concept. I will outline the project below;
The project is a automatic bollard system whereby bollards are risen or brought back down by a motor that takes input from a range of stimuli. The motor will be connected to a microcontroller (Arduino or Adafruit ESP32). The motor’s power will be supplied by a separate power supply. The bollards will stay activated until inactivated manually by the user. Knowing where the bollard is would be useful. I know a DC Motor with an encoder may work but I will need assistance in selecting the correct motor and encoder for the task.
Ideally the cost should be kept under £75.
Thanks for the help!
