How is the electrical system of electric forklift developed?

As an electric forklift, the electrical system is an important part of the electric forklift, which includes walking, lifting, steering controller, DC-DC steering controller and on-board charger. As we all know, the development and progress of electric forklift has a process, so does the electrical system of electric forklift. It is very meaningful for forklift buyers and forklift drivers to know these things. Next, Electric Forklift Manufacturer will tell you about the development of the electrical system.

In general, the traveling motor of electric forklift has gone through the development process from DC series excitation electric control to DC separate excitation electric control, and now widely used AC electric control. DC separate excitation electric control has many advantages over DC series excitation electric control. It can prevent the electric forklift from sliding down the ramp, making the driving of the electric forklift safer. This is beyond the capability of DC series excitation electric control. Moreover, the pulsation of the working current of the battery and motor is greatly reduced after using the separately excited electric control, and the electric forklift can run at the maximum speed under the conditions of no load and full load. In addition, there are no traditional three controllers for separately excited electric control: reversing contactor, full speed contactor and regenerative contactor. The advantage of this is not only to reduce the burden of the electric forklift, but also to fundamentally solve the problem of easy arcing of the contactor and frequent failures. Electric forklift manufacturer tells us that this greatly saves maintenance costs.

So, what are the advantages and characteristics of AC electric control, which is now widely used on electric forklift? It is controlled by constant torque at low speed and constant power at high speed. In the low speed section, it has the function of voltage compensation, which makes the climbing ability of electric forklift stronger. Moreover, AC motor has the function of speed feedback, which makes the operation more sensitive and the power better controlled. In addition, AC motors no longer use electric shock and brushes, making maintenance easier. It can also communicate with other components through the CAN bus. The electric forklift manufacturer told us that once a fault occurs, it can be quickly detected by the computer, making the fault detection more convenient.

The development and application of emerging electrical systems make electric forklift safer, easier to operate and more superior in performance. Now, all major electric forklift manufacturer have successively launched all AC driven forklifts, with a driving speed of 17km/h and a climbing gradient of 20%. Our electric forklift manufacturer is also keeping pace with the times and constantly innovating, and have launched electric forklifts equipped with high-performance electrical systems for consultation.
