SUMMARY

To calculate the motor size for a trolley with a pulley system, three primary forces must be considered: the force required to climb any slope, the force to overcome rolling resistance, and the force needed to accelerate from rest to maximum speed. The rolling resistance depends on the surface type and tire characteristics, which may require measurement or estimation. Accurate calculations of the first and third forces can be achieved through established formulas based on mass and acceleration requirements.

PREREQUISITES
  • Understanding of basic physics principles, specifically Newton's laws of motion.
  • Knowledge of rolling resistance factors, including surface type and tire specifications.
  • Familiarity with force calculations, including gravitational and acceleration forces.
  • Experience with pulley systems and their mechanical advantages.
NEXT STEPS
  • Research methods for calculating rolling resistance in various surface conditions.
  • Study the principles of pulley systems and their impact on motor torque requirements.
  • Learn about the formulas for calculating force based on mass and acceleration.
  • Explore electric motor specifications and sizing based on load requirements.
USEFUL FOR

Engineers, mechanical designers, and hobbyists involved in building or optimizing trolley systems and electric motor applications.

I want to build a trolley with four wheels and towed to a rope having pulley on both ends connected to a electric motor. one of the pulley will be drive and other will be idle. what will be the proper procedure to calculate the motor size for this type of problem. thanks in advance

First you will need to know the forces required to move and or accelerate the trolley. You could break the total force down into three parts...

1) Force required to climb slope if any.
2) Force required to overcome the rolling resistance (Depends on smooth or rough surface? Type of tyres, pressure etc)
3) Force required to accelerate from rest to max speed. Depends on mass and acceleration required.

Some things can be calculated (such as 1 and 3) but 2 may have to be measured or estimated.
