The relation between motor speed and pulley diameter
At the speed of your machine you can see that you have a few levels of the motor on top of the brand name and 3000, 1500, 750 and so on You must know the diameter of the wheel on your motor shaft N1 N2 = D2 / D1 N1 = motor speed N2 = belt wheel speed D2 = pulley diameter D1 = motor shaft wheel diameter To understand the
The motor speed is - fixed, it has no relation to the pulley diameter of the pulley. It's all about the wheel speed and the diameter of the pulley
Specifically, can have a drive shaft directly connected between motor and belt pulley, also have through the other transmission device, such as gear meshing, too general a bad answer
