This devices are mainly used for governing the speed in the machinery. Two main causes of maintaining the rate of machinery by using variable speed drives are to regulate the process also to conserve energy. Though these drives are produced for process control, energy conservation is becoming its prime objective.

Many industrial processes need different speed to operate different products. We can save energy by controlling the speed of those processes. Since we are able to find the speed from the pre-set ranges, it's called the "adjustable" speed. This can be referred as variable speed because its output could be changed without undergoing any steps. These are purely mechanical variations.

Some advantages of using VSD are, they give smoother operation and acceleration control and enable you to choose different speed for each process, decrease operation for setup purposes, adjust rate of production, control torque, and compensate variables in changing process.

DC Drive Systems are vital for anything which has a DC Electric Motor, whether it's a golf trolley, electric wheelchair or other type of drive system. But how do they work? What are they made of? And how does one obtain the most value from it?

First a small primer on DC Motors. DC motors are used in the number of applications the place where a petrol or an AC engine will be too wasteful. They are primarily used in mobility systems such as electric wheelchairs or golf trollies, but could be used as pinsetters in bowling alleys, winching equipment & other static devices. They use a tiny direct current (which is really an alternative current converted to DC) to produce a large amount of power and torque. This is basically due on the drive system inside system.

To begin with, there's the electric motor. This - when connected to a source of energy (usually a battery or on the mains) - drives the engine. For choosing an engine for the drive system, don't skimp on quality. The engine is absolutely vital, and although cost and space constraints have to be taken into account, skimping on reliability can drastically affect your drive system. If you're after having a buyers suggestion, generally speaking, it should be minimal powerful engine required to sufficiently do your task.
