An electricbattery is a device consisting of two or more electrochemical cellsthat convert stored chemical energy into electrical energy. Eachcell has a positive terminal, or cathode, and a negative terminal,or anode. The terminal marked positive is at a higher electricalpotential energy than is the terminal marked negative. The terminalmarked positive is the source of electrons that when connected toan external circuit will flow and deliver energy to an externaldevice. When a battery is connected to an external circuit,Electrolytes are able to move as ions within, allowing the chemicalreactions to be completed at the separate terminals and so deliverenergy to the external circuit. It is the movement of those ionswithin the battery which allows current to flow out of the batteryto perform work.[1] Although the term battery technically means adevice with multiple cells, single cells are also popularly calledbatteries.
Primary(single-use or "disposable") batteries are used once and discarded;the electrode materials are irreversibly changed during discharge.Common examples are the alkaline battery used for flashlights and amultitude of portable devices. Secondary (rechargeable batteries)can be discharged and recharged multiple times; the originalcomPOSTTTION of the electrodes can be restored by reverse current.Examples include the lead-acid batteries used in vehicles andlithium-ion batteries used for portable electronics.
电池是一种由两个或多个电化学电池组成的装置，将储存的化学能量转化为电能。每个电池都有一个正极或阴极，还有一个负极。V端子，或阳极。标记为正的端子具有比负端子更高的电势能。标记为正的终端是当c时电子的来源。连接到外部电路将流动和传送能量到外部设备。当电池连接到外部电路时，电解液能够以离子的形式在内部移动，从而使化学物质得以运行。校准将在单独的端子处完成并且将能量传递到外部电路。这就是这些离子在电池内的运动,其允许电流从电池中流出,Ry执行工作。[1]术语“电池技术”是指具有多个电池的器件，单个电池也被称为电池。
一次(一次性或“一次性”)电池被一次性使用和丢弃，电极材料在放电过程中发生不可逆转的变化。常见的例子是用于闪光灯的碱性电池。紧身衣和许多便携式设备。二次(可充电电池)可多次放电和充电；电极的原点可通过反向电流恢复。租金。例子包括用于车辆的铅酸电池和用于便携式电子产品的锂离子电池。
Batteries come inmany shapes and sizes, from miniature cells used to power hearingaids and wristwatches to battery banks the size of rooms thatprovide standby power for telephone exchanges and computer datacenters.
According to a2005 estimate, the worldwide battery industry generates US$48billion in sales each year,[2] with 6% annual growth.
Batteries havemuch lower specific energy (energy per unit mass) than common fuelssuch as gasoline. This is somewhat offset by the higher efficiencyof electric motors in producing mechanical work, compared tocombustion engines.
电池有多种形状和大小，从用于为助听器和手表供电的微型电池到为电话交换机和comp提供备用电源的房间大小的电池组。数据中心。根据2005年的估计，全球电池行业每年的销售额为480亿美元，年增长率为6%。电池的比能量(能量)要低得多。(每单位质量y)比普通燃料(如汽油)。与内燃机相比，电机的机械工作效率更高，这在一定程度上抵消了这一现象。

①液压和气压驱动:响应速度慢、精度低,伴随着焊接机器人伺服驱动系统对响应速度、控制精度要求的提高,液压和气压驱动正逐步退出市场;
②直流电机伺服:直流伺服具有精度高、控制系统简单等优点，是当前伺服系统的主流。存在电刷机械换向机构，换向时的打火现象可能对工作现场的安全造成危害，机械换向机构易磨损，不利于伺服系统的持续可靠工作，且维护困难;
③交流永磁同步电机伺服:质量功率比小,无机械换向机构,易维护,但控制系统较为复杂,不易实现高精度控制。随着技术发展,交流同步电机逐步具备了宽调速范围、高稳速精度、快速动态响应及四象限运行等良好的技术性能,正逐步取代直流电机。
每台多轴机器人由一套控制系统控制,这也意味着控制器性能要求较高。一旦控制器因为电力问题(断电、浪涌、过、低压等)发生误动作、宕机、甚至引发数据丢失,将引发重大事故。在分析控制器的输入端前加配的稳压电源故障后,发现造成稳压电源98%的故障即不能正常工作,是因为电压暂降即“晃电”引起的,稳压电源的配置有天生缺陷,应选用工业型UPS。
