Description
Technical Field
The utility model relates to a belt feeder motor field, concretely relates to belt feeder system based on converter speed governing.
Background
Construction waste disposal projects are generally provided with a plurality of conveying devices, the conveying devices convey various construction wastes to various screening devices or crushing devices, and the most common conveying device is a belt conveyor.
However, the motor of the existing belt conveyor is generally started by a contactor at direct power frequency, and the power frequency is fixed to be 50Hz, so that the belt conveyor is difficult to realize real-time speed regulation.
Moreover, the instantaneous current for starting the belt conveyor motor is too large, usually 4-7 times of the rated current, the current fluctuation is unstable, and the service life of the motor is greatly shortened after long-term use. Especially, when the high-power belt conveyor is started, the impact on a power grid is easily caused by overlarge current.
