    Design Of A Power Saving Industrial Conveyor System

    Most industrial conveyor systems have continuous operation without stopping for the reason of avoiding high power consumption during starting and stoppage of the system. High starting power will result high starting torque and shock loads giving rise to problems of short belt life due to more tension and also leads to more energy costs.

    Suitable Softstarter For Application With Conveyor Belts

    Sep 07, 2015 Conveyor belts often need a starting torque very near or just above the rated torque of the motor. A direct-on-line start with a normal squirrel cage motor gives approx. 1.5 to 2.5 times rated torque of the motor depending on motor size, type etc. When making a direct-on-line start there is a very high risk of slipping between the belt and the driving role depending on this high starting torque.
