电动叉车交流电机与直流电机区别?
What is the difference between AC motor and DC motor of electric forklift?
交流电机
alternating current dynamo
是用于实现机械能和交流电能相互转换的机械。由于交流电力系统的巨大发展,交流电机已成为常用的电机。交流电机与直流电机相比,由于没有换向器(见直流电机的换向),因此结构简单,制造方便,比较牢固,容易做成高转速、高电压、大电流、大容量的电机。交流电机功率的覆盖范围很大,从几瓦到几十万千瓦、甚至上百万千瓦。20世纪80年代初,汽轮发电机已达150万千瓦。
It is a machine used to realize the mutual conversion of mechanical energy and AC energy. Due to the great development of AC motor, AC motor has become a common power system. Compared with DC motor, AC motor has no commutator (see commutation of DC motor), so it has the advantages of simple structure, convenient manufacturing, relatively firm, easy to make high speed, high voltage, large current and large capacity motor. AC motor power covers a wide range, from a few watts to tens of thousands of kilowatts, or even millions of kilowatts. In the early 1980s, the steam turbine generator has reached 1.5 million kilowatts.

直流电机
DC motor
定义输出或输入为直流电能的旋转电机,称为直流电机,它是能实现直流电能和机械能互相转换的电机。当它作电动机运行时是直流电动机,将电能转换为机械能;作发电机运行时是直流发电机,将机械能转换为电能。
The definition of output or input as DC power of the rotating motor is called DC motor, which can realize the conversion of DC power and mechanical energy. When it works as a motor, it is a DC motor, which converts electrical energy into mechanical energy; when it works as a generator, it is a DC generator, which converts mechanical energy into electrical energy.
交流驱动的优势
Advantages of AC drive
采用交流驱动系统的电动叉车,整体性能显著提高,故障及元件更换率明显降低,可靠性大大增强;叉车单位时间的生产率更高,操作及维护成本更低,将给用户带来非常显著的效益。因此,交流驱动系统一经推出,不仅得到了叉车生产企业的信赖,也越来越受到用户的青睐,成为近年来电动叉车技术发展的趋势与方向。其优势主要体现在以下方面:运行与维护成本低交流电机终生免维护。
The overall performance of the electric forklift with AC drive system is significantly improved, the failure and component replacement rate is significantly reduced, and the reliability is greatly enhanced; the productivity per unit time of the forklift is higher, and the operation and maintenance cost is lower, which will bring very significant benefits to users. Therefore, once the AC drive system is launched, it is not only trusted by forklift manufacturers, but also favored by more and more users. It has become the trend and direction of electric forklift technology development in recent years. Its advantages are mainly reflected in the following aspects: low operation and maintenance cost, AC motor life-long maintenance free.
交流电机无需换向接触器(前进、后退换向),节省了部件。更为重要的是,交流电机无碳刷和换向器,不仅电机的体积更加轻便小巧,运转速度提高了,而且彻底摆脱了定期检测和更换碳刷的麻烦。由此带来的好处是:叉车电机几乎终生不需要维护,很大地增强了叉车的可靠性与稳定性;同时,在叉车设计时不用考虑预留电机维修空间,甚至可以将电机密封起来,使叉车结构设计更加紧凑。
AC motor does not need reversing contactor (forward and backward reversing), saving parts. More importantly, AC motor without carbon brush and commutator, not only the volume of the motor is more light and compact, the operation speed is improved, but also completely get rid of the trouble of regular detection and replacement of carbon brush. The advantages are: the forklift motor almost does not need to be maintained for life, greatly enhancing the reliability and stability of the forklift; at the same time, the forklift design does not need to consider the reserved motor maintenance space, or even can seal the motor, making the forklift structure design more compact.
