Discussion Overview

The discussion centers on identifying an appropriate motor for controlling slider crank motion, with a focus on motor speed regulation and the specific requirements of the application.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the necessary speed, force, and work required for the slider crank motion.
  • Another participant specifies that the motor should operate at a controlled rotation speed between 200-400 rpm, with a small magnet attached to the slider.
  • Some participants suggest that many small electric motors could be suitable for the task, emphasizing that the construction of the slider crank and motor mounting will influence the choice of motor.
  • There are suggestions regarding speed regulation of a small DC motor through supply voltage adjustment, and torque regulation through current control or the use of a series resistor.

Areas of Agreement / Disagreement

Participants express differing views on the specific motor requirements and methods for speed and torque regulation, indicating that multiple competing perspectives exist without a consensus.

Contextual Notes

Participants have not provided specific details on the force requirements or the work to be done by the slider crank, which may limit the applicability of their suggestions.

which motor is reasonable for slider crank motion , where the motion of slider should be control with motor speed.

Thank you

the motor should be controlled rotation between 200-400rpm , a small magnet will be attached at the end of slider

There are too many possibilities. Almost any small electric motor will do the job. How you construct the slider crank, and mount the motor, will depend on your choice.

To regulate the speed of a small DC motor, you should regulate the supply voltage.

To regulate the torque of a small DC motor, you should regulate the current, or use a series resistor.
