The difference between electric forklift exchange and DC technology:First, the motor is automatically maintained
The electric forklift of the AC drive system, the overall performance is significantly improved, the fault and component change rate is significantly reduced, the reliability is greatly enhanced; the productivity of the forklift unit time is higher, the operation and maintenance cost is lower, will bring very significant benefits to users. . Therefore, the exchange-drive system has been launched, not only the trust of the forklift production enterprise, but also is increasingly favored by the user, and has become the trend and direction of the development of electric forklift technology in recent years. Its advantage is mainly reflected in the following: operation and maintenance cost low AC motor.
The AC motor does not need to reverse the replacement (forward, retreat), saving components. More importantly, the AC motor has no carbon brush and commutator, not only the size of the motor is smaller, but the speed is improved, but it is completely joined to regularly detect and replace carbon brush. The greatest advantage of this is that the forklift motor does not require maintenance, which greatly enhances the reliability and stability of the forklift; Make the forklift structure design more compact.
Second, the regeneration braking function
Reducing wear regeneration braking is a non-contact brake, which is greatly simplified than traditional brake systems. Whether the driver brakes in the brake pedal or the driving direction of the traveling direction, the motor is in the generator state, and the electromagnetic torque will become a torque of braking properties. This means that the wear of the brake pads minimize. The mechanical wear is greatly reduced, and the forklift maintenance cost is reduced, which makes the operating cost lower. At the same time, the efficiency of the AC motor is higher in driving and braking. When braking or commutation, there will be regenerative energy generation. The stronger the brake, the more energy is regenerated. The energy storage device of the AC drive system will automatically start when the brake or commutation, and the energy is returned to the battery, so that the battery is extended, and the life is longer. Although there are regenerative brakes on some DC drive forklifts, it must be enabled in a strong brake, which means that some of the energy of regeneration is converted into heat during brakes. In all cases, the AC motor will generate energy regeneration, and continue to actually be completely stationary, obviously higher than the energy regeneration efficiency of DC motor.
Third, accelerate faster, improve efficiency
The maximum speed of the AC motor is much higher than the DC motor, and the power is more powerful. Moreover, the AC motor can feed back the obtained regenerative energy to the battery, extending both the battery usage, and can use these energy to improve the overall performance of the forklift. As a result, the forklift was started faster, accelerated / deceleration performance, shortening the time and walking distance studies to achieve the highest speed showed that in most actual use, the forklift self-starting to the stop of the handling job is very Less than 20m. The excellent acceleration performance of the AC motor makes it possible to achieve full speed of the forklift within such a short distance, and the working efficiency of the forklift is significantly improved.
Fourth, the operation is more flexible
AC drive systems have different effects from improving the comfort of the forklift driver's operation. Since the AC motor is smaller than the DC motor, this makes the design of the forklift more flexible. For example, using this flexibility, the space can be effectively arranged, so that the components such as the tubing, the harness can be reasonable, and the center of gravity can be reduced, so that the stability of the whole vehicle is better, and the driving is more comfortable. In short, the exchange-driven system is used as a forklift to update the technique, and it will be more widely used. This is known as the "revolutionary technology of the electric forklift in the 21st Century", the technical level, product sales, market share, profit and even innovative image, etc. of the forklift enterprises. After all, the future competition is more embodied as the context of technology. Who masters new technologies, who can win more advantages in the future market, occupying more favorable positions. It can foresee the forklifts manufactured in China in the next five years. In terms of technology, more important trends is that with the development of control technology, the development of electric forklift power systems requires motor and electric control matching each other.
