The speed ratio i between the input speed and output speed of the gear unit serves as a measure of this. Another important measured variable for a gearmotor is the maximum torque on the output side. This torque is specified in newton meters (Nm) and is the measurement for the force of the gearmotor and the load that it can move with that force.

The industrial power transmission market works with basic power transmission open-drive products like belt drives, chain drives, gear drives and each has its own set of advantages and disadvantages. In this post, we will look into the pros and cons of these components of power transmission technology.

The ideal location for the drive of a belt conveyor is the place which minimizes belt tensions both during the acceleration and running periods. Although circumstances may dictate that a drive be located somewhere between the ends of a conveyor, locating it at the head end when the conveyor has to be powered to drive it is preferred.
