An Energy-Saving Control System for an Orbital Electric Driver of a Press Coupler

详细

A control system for the orbital electric drive of a press coupler capable of reducing energy consumption is considered. Because the stator is not completely overlapped by rotors, it is proposed to reduce the power consumption by means of turning off the power supply from the unused part of the rotor. This requires use of a rotor-positioning sensor as well as an algorithm for determining the overlap area depending on the position of the rotors. A calculation algorithm, which can be applied to orbital electric drives of different configurations, is presented. The algorithm creates rotor and stator maps depending on the angle and the sought overlap area is obtained by overlapping one map on another. This allows applying the optimization methods for finding an optimal control algorithm.
