ABB UNS2882A 3BHE003855R0001 controller

Description

ABB UNS2882A 3BHE003855R0001 controller  refers to the master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in accordance with the predetermined order. Composed of program counter, instruction register, instruction decoder, timing generator and operation controller, it is a “decision mechanism” that issues commands, that is, to complete the coordination and command of the operation of the entire computer system.

The motor controller is mainly composed of the following parts:

1, electronic control module (ElectronicController) Electronic control module includes hardware circuit and corresponding control software. The hardware circuit mainly includes the microprocessor and its minimum system, the monitoring circuit of the motor current, voltage, speed, temperature and other states, various hardware protection circuits, and the communication circuit with the vehicle controller, battery management system and other external control unit data interaction. The control software realizes the corresponding control algorithm according to the characteristics of different types of motors.

2. Driver The driver converts the control signal of the microcontroller to the drive signal of the drive power converter, and realizes the isolation of the power signal and the control signal.

3, power conversion module (PowerConverter) Power conversion module to control the motor current. The power devices often used in electric vehicles include high-power transistors, gate turn-off thyristors, power field effect tubes, insulated gate bipolar transistors and intelligent power modules.
