Adjustable speed drive (ASD) or variable-speed drive (VSD) describes equipment used to control the speed of machinery.

Many industrial processes such as assembly lines must operate at different speeds for different products.

Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control.

A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel.

Belts may be used as a source of motion, to transmit power efficiently, or to track relative movement.

Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts).

As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points.

A sprocket or sprocket-wheel is a profiled wheel with teeth, cogs, or even sprockets that mesh with a chain, track or other perforated or indented material.

The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it.

It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.

Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

A machine is a tool containing one or more parts that uses energy to perform an intended action.

Machines are usually powered by chemical, thermal, or electrical means, and are often motorized.

Historically, a power tool also required moving parts to classify as a machine.

However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.
