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.
