Hi guys

I need a motor for my project, but I´m not quite sure if my calculations are correct.

I need a motor to drive 10 kg on a linear slide, where the friction constant is 0.1. The motor will drive a belt the the object is fixed to the belt.

To calculate the force required to move the object:

F = m * g *u , F = force, m = mass of object, g = gravity constant, u = friction. F = 10 kg * 9,82m/s2 * 0,1 F = 9,82 N to push the object. That must be right.

Calculating the motors torque:

T = F * d, where T = torque, F = force, d = distance

T = 9,82 N * 0,01 m (distance from motor shaft to belt) T = 0,0982 Nm

Is that right, that I dont need a larger motor, or am I missing something? Is the distance when using torque meassured from the center point of the shaft or on the shafts edge?

Kind regards Kasper
