Electric technology drives the development of electric forklifts The oldest and most traditional series of DC electric forklifts have been gradually eliminated. Because the traditional electric forklifts are to deliver power to the battery and turn dry, so there is current using carbon brushes to transport, and carbon brushes It is a consumable part and needs to be replaced regularly. Not only is the performance determined by the carbon brush, which limits the performance of the braking performance, and the carbon brush is a wearing part and needs to be replaced regularly, otherwise it will be Affects motor life.
Therefore, in order to solve this problem of the majority of users, electric forklift manufacturers have a more advanced DC electric forklift. This electric forklift is the same as the series motor. This technology uses separately excited excitation magnetic field and armature. However, this motor has better performance than a series motor, but its defect is the same as that of a series motor.
Later, there was a three-phase AC motor, which is technically relatively simple. The principle is to deliver three-phase alternating current to a fixed coil, producing a rotating magnetic field that induces a voltage on the shorted rotor. This type of AC motor has no carbon brush, so there is no defect in the carbon brush, and there is no limitation on the maximum current of the DC motor. Therefore, it is the inevitable development trend of electric forklift power. The heat generated by this motor is mainly in the fixed sub-coil of the motor casing, which is good for cooling and heat dissipation, and the rotor can be sealed according to requirements. Without a carbon brush, there are no consumables that need to be replaced regularly.
At the same time, it also features high performance, maintenance-free, high reliability, high efficiency and low cost. Therefore, many electric forklift companies are currently switching from DC technology to AC forklifts. With the development of technology, as China's electric forklift market gradually integrates with the international market, China's AC drive technology is accelerating, so its market potential is huge. Welcome to the company ***http://
When the AC drive system is used as a new technology for electric forklift replacement, it will have a certain impact on the technical level, product sales, market share, profit and even the image of the electric forklift enterprise. This technology will also be used more and more widely in the future. The competition of future enterprises will be technical competition. With the development of control technology, the development of electric forklift power system will require the matching of electric motor and electronic control, and the enterprise masters this core technology, which will be in the future. Win more markets in the market.
