[CN 202111643267.9] Electric Energy Management System of Servo Press
[CN 202111643267.9] Title of Electric Energy Management System for Servo Press: Application Number of Electric Energy Management System for Servo Press: CN 202111643267.9 Applicant: Jinfeng (China) Machinery Industry Co., Ltd. Application Date: 2021-12-29 Patent Type: Invention Application The present invention discloses an electric energy management system for servo press, which is characterized by comprising a rectifier and an inverter, and an AC input end of the rectifier is externally supplied with power, the rectifier is electrically connected with the inverter through a DC bus, the inverter is electrically connected with the servo motor in the servo press, the DC bus is connected with a capacitor bank, the capacitor bank is connected with a first current-limiting resistor, a second current-limiting resistor and an energy-releasing resistor, a first DC contactor is connected between the DC output end of the rectifier and the first current-limiting resistor and the second current-limiting resistor, A third DC contactor is connected to the DC bus; the advantage is that it can greatly reduce the power requirements for the input grid, reduce the cost of electricity, and protect the grid well, reduce the requirements for the grid, and reduce energy waste.
