[Abstract]:Compared with the internal combustion forklift, the electric forklift has the advantages of no pollution, low noise, high energy efficiency and so on. In recent years, with the enhancement of the social awareness of environmental protection, the technology of the electric forklift truck has been rapidly developed, and the market quantity has been increased year by year. The driving system as its core has become the focus of current research. In this paper, the design of permanent magnet synchronous motor driver for forklift truck is completed. This paper first introduces the development of electric forklift at home and abroad and the advantages of AC drive technology of electric forklift, and deeply studies and analyzes the structure characteristics, mathematical model, vector control method and SVPWM wave generation principle of permanent magnet synchronous motor (PMSM). On this basis, a control scheme of forklift permanent magnet synchronous motor driver is presented. The high performance DSP chip TMS320F2812 is used as the core of the control circuit. The main loop inverter is triggered by the output PWM signal of the control circuit to realize the drive of the permanent magnet synchronous motor (PMSM). According to the characteristics of electric forklift and inverter circuit, peripheral circuits such as forklift overcurrent protection circuit, battery under-voltage monitoring circuit, battery overvoltage alarm circuit, power MOSFET driving circuit, inverter circuit, forklift parameter programming monitoring interface and so on are designed. Finally, the system is comprehensively debugged, and a large number of experiments are carried out. The experimental results show that the permanent magnet synchronous motor driver of forklift can meet the requirements of forklift operation, and it is reliable and has good practical value.
