An Introduction to Track Conveyance Systems

A belt conveyor is prone to wear, requires scheduled maintenance, and is typically not very fast. The belt is usually driven by an asynchronous motor with a VFD (variable frequency drive), meaning the conveyor is rather on or not, but can also be driven with a servo for accurate positioning. Figure 1. An assembly conveyor.

Selecting the Optimal Conveyor Drive

There is a strong trend for variable speed fixed conveyors to be driven by a three-phase AC motor working with a variable frequency drive (VFD.) The use of DC motors to drive variable speed belt conveyors is declining because of the lower motor and control cost and high reliability of the AC motor/VFD concept. See figure 13.

Introduction to Conveyor Belt Systems

The belt is stretched across the conveyor length with pulleys at both ends to support the belt. A driving mechanism such as an electric motor rotates the pulleys, which moves the belt across the conveyor length. The belt's speed can be fixed or variable, depending upon the application required.

Here's my answer, without getting into the problems of VFD control of a single phase motor and the pros and cons of varying the conveyor speed in an assembly line. The 'speed vs power' and 'speed vs torque' curves of a motor are shown below. Energy savings would be possible should working speeds be prevalent in the constant torque zone.

How to Calculate Conveyor Belt Speed | Sciencing

The speed at which the conveyor belt moves depends on the size of the rollers and their revolutions per minute. Measure the diameter of the rollers around which the conveyor belt is wrapped. Multiply the diameter of the roller by pi, 3.14159. This calculation yields the circumference of the rollers.
