centrifugal device) are dependent on the speed of the coupling, and in particular, reduction in speed from those conditions identified in the selection tables will cause diminishing performance . All variable speed or multi-speed applications should be referred to the Factory to determine whether a fluid coupling is suitable for the application .
The input stage of the Inverter Drive is a one way power device, while the output stage allows power to flow in both directions. It follows that inertia of a load will return its stored energy to the Inverter Drive when an attempt is made to slow its speed at a greater rate …
Among typical uses for these positive drive conveyor belts are removal of heat treated parts from quench baths, washing and drying applications and the handling of products in the food processing industry. While the belt is long or the article is heavy, you should choose chain drive to …

May 06, 2015· If you can find another solution with a textile belt or some kind of non slip drive the power requirement will be reduced and maybe a windshield or other geared dc motor will do. Adjusting the speed will be much easier but you have to take into account that the speed will be more load dependent than with an ac motor.
Overhead conveyors are great when paired with control systems and variable speed drives; ensure these specifications are given to your supplier, if needed for your application. Also, provide the working environment for the conveyor, as certain working conditions (corrosive, humid, dry, etc.) will affect conveyor performance.
An endless polyurethane 'troughed' belt conveyor mounted on a braced rigid frame takes the product over an integral weigh bed section. The unit is supported on an open framework. A microprocessor-based weigh controller conditions load cell and belt speed signals to generate outputs of rate (tonnes/hr., kg/m) and total weight conveyed.
supplies DC electric charge to the 12V DC motor as the conveyor drive, and increases the value DC electric current that comes out of the automatic timer circuit on relay 1 which supplies DC electrical charge to the 12 V DC motor as the conveyor drive, the conveyor speed increases, and the car washing process takes longer.
conveying capacity. The conveying capacity and material loading rate of the belt conveyor can be adapted to the actual material flow by lowering the belt speed [3]. Figure 1.1 and 1.2 shows the belt conveyor system used in this project. This conveyor system is driven by a DC motor equipped with the driver for direction and
