The pole-changing two-speed motor system of the electric order picker reclaimer is the most simple, economical, and practical. The disadvantage is that the speed change range is limited, and it is difficult to obtain good high-speed and low-speed characteristics at the same time. The common speed ratio of the order picker is 1/2 and 1/4. When the motor switches from high speed to low speed, it is in the state of generator braking, which makes the motor slow down. For the hoisting mechanism, the high-speed and low-speed characteristics of the motor should be properly selected, so as to obtain a good braking torque when changing speeds. The pole-changing motor is suitable for occasions where the speed regulation ratio is not large and the speed regulation process is not strictly controlled, such as the telescopic mechanism of the order picker and the hoisting mechanism and running mechanism with a small speed regulation ratio.
The high-end self-propelled order picker eddy current brake closed-loop speed regulation system consists of a winding motor and an eddy current brake fixed coaxially with it. After the difference between the actual speed sampling of the motor and the given speed is amplified, it is fed into the eddy current brake to adjust its excitation current to regulate the motor speed. The electric order picker reclaimer system can obtain low and hard speed regulation characteristics, and the speed regulation ratio can reach more than 20. It is more suitable to realize depth adjustment on the stacker hoisting mechanism and running mechanism.
