Title: Innovations of Xiaojun Zhang

Introduction

Xiaojun Zhang is a notable inventor based in Peoria, IL (US), recognized for his contributions to the field of electromagnetic lift systems. With a total of five patents to his name, he has made significant advancements that enhance the efficiency and safety of material handling operations.

Latest Patents

Among his latest patents is a "System and method for controlling electromagnet lift power for material handlers." This innovative method involves operating an electromagnetic lift that includes a generator-driven electromagnet. It comprises adjusting the position of the electromagnet in response to a first position command. Upon receiving a lift command, the output power level of the generator is established at a predetermined level above a predefined normal power level. In response to an excess release command, the output power level is set to a first predetermined level below the normal power level. For transport commands, the output power level is maintained at approximately the normal power level. Upon receiving a release command, the output power level is established at a second predetermined level below the normal power level.

Another significant patent is the "Overload protection system for an electromagnetic lift." This method protects against current overload conditions associated with an electromagnetic lift system. It involves receiving current data from a monitoring device and determining a current level based on this data. If the current level exceeds an overload current threshold, the method identifies a predetermined overload range. It also includes monitoring the duration that the current level remains within this range and providing a command signal to an actuator if the time exceeds a predetermined limit. This command signal effectively limits the mechanical power provided to the generator, ensuring safety and reliability.
