Modularbelt conveyor with variablespeed drive motor . European Patent EP . Kind Code: B1 . Abstract: Abstract of EP A conveyor system in which a modular belt or chain is driven by a drive element rotated at a predetermined variable angular speed to compensate for speed fluctuations due to chordal action. A speed signal generator generates a speed signal generally inverse to the

Ein Differentialtransformator, im Rmen der Wegemessung auch als englisch Linear Variable Differential Transformer, abgekürzt als LVDT, bezeichnet, ist eine Spezialform eines besteht in der Regel aus einer Primärspule und zwei Sekundärspulen. Letztere sind gegenphasig in Reihe geschaltet, dadurch subtrieren sich die Spannungen an ihren Anschlüssen.
Das Konzept der Varianz geht auf Carl Friedrich Gauß zurück. Gauß führte den mittleren quadratischen Fehler ein, um zu zeigen, wie sehr ein Punktschätzer um den zu schätzenden Wert streut. Diese Idee wurde von Karl Pearson, dem Begründer der Biometrie, ü ersetzte, für dieselbe Idee, den von Gauß geprägten Begriff mittlerer Fehler durch seinen Begriff Standardabweichung.
Variablespeed drives for belt conveyor systems, Nov 2000 7 ABB Process Industries Open Pit Mining Materials Handling, Cottbus/Germany Fig. 9: Diagnostic tools on a conveyor Summary Some of the benefits of controlled drives are • an optimum loading of the belts through controlling the belt speed, depending on the load volume, in the range of m/s; reference values are supplied
Variablespeed drives can also run a motor in specialized patterns to further minimize mechanical and electrical stress. For example, an Scurve pattern can be applied to a conveyor application for smoother deceleration and acceleration control, which reduces the backlash that can occur when a conveyor is accelerating or decelerating.

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semisolid materials, including food waste, wood chips

Variable Speed Drive Adjust to minimum speed for sufficient chip removal and reduce coolant losses.
Variable Speed Conveyor System This little SmartMove® conveyor system is used for packaging food items. Having a variable speed motor is a must, as the operator needs to adjust the speed based on the amount of the product coming off the line.
Variablespeed drives for beltconveyor systems ABB – Openpit Mining, Cottbus/Germany 5 Fig. 7: Drive design Guiding principles for dimensioning the drives have been not only the mechanically required torque but also the objective to use common hardware as far as possible. Another important criterion has been the demanded high availability of the system. This is why a socalled emergency

Our portable Variable Speed conveyor is the ideal choice when speed adjustment is vital to your job. The VFD controls allow for materials to move as slow as 5'' per minute, or as fast as 133'' per minute. This standalone conveyor is complete with builtin controls eliminating the need for an external control box and terminator plug as are used with our system conveyors.
Most conveyor applications involve an elementary speed control strategy in which the drive simply regulates the operating speed at a setpoint that may be adjusted from time to time. The speed setpoint might be set manually by an operator or automatically by supervisory control equipment. When an adjustable speed drive is used with a conveyor to regulate a process variable, indirect control is
Accumulation conveyor that utilizes a decentralized drive system with a pancake motor located in each zone. Each motor has ability to run at a selected speed bringing ultimate versatility to this conveyor type. Best for manufacturing, warehousing, picking, food beverage. Benefits are compact design, quiet operation, variable speed adjustments

A DC motor''s speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion

A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another. Conveyors are especially useful in applications involving the transport of heavy or bulky materials. Conveyor systems allow quick and efficient transport for a wide variety of materials, which make them very popular in the material handling and packaging industries.
Variable Speed Controller Warnings − General Safety A WARNING The safety alert symbol, black triangle with white exclamation, is used to alert you to potential personal injury hazards. A DANGER Climbing, sitting, walking or riding on conveyor will cause severe injury. KEEP OFF CONVEYORS. A DANGER DO NOT OPERATE CONVEYORS IN AN EXPLOSIVE
