When classifying electric forklift inverters according to their purposes, they can be divided into the following types:
As the name suggests, the general inverter is characterized by its versatility. The general-purpose inverter can control the speed of the asynchronous motor of the electric stacker.
High-performance special frequency converter, with the development of control theory, AC speed regulation theory and power electronic technology, the vector control method of the asynchronous motor of intelligent electric forklift has been fully valued and developed. The electric forklift adopts the vector control method of high-performance frequency converter and frequency conversion The speed control system composed of the special motor for the machine has reached and surpassed the DC servo system in performance.
High-frequency inverters often use high-speed motors in the area of ultra-precision machining and high-performance machinery. In order to meet the needs of these high-speed motor drives, frequency converters for high-speed motor drives using PAM control methods have appeared. The output frequency of this type of inverter can reach 3KHz, so the maximum speed of the motor can reach 180000r/min when driving a two-pole asynchronous motor.
Single-phase inverter and three-phase inverter AC motors can be divided into two types: single-phase AC motors and three-phase AC motors. Electric forklift stacker inverters are also divided into single-phase inverters and three-phase inverters. The two work on the same principle, but the structure of the circuit is different.
