车博客全自动洗车机核心技术之直驱科技
车博客洗车机采用德国品孚PW60高压柱塞泵，是品孚厂家为车博客专属定制款,配合15KW六级电机，采用联轴器方式直驱驱动，运行稳定，安全高效，免维护。
如果采用传统皮带轮传动链接方式，皮带运行容易产生危险的同时，皮带老化需要定期更换，容易出现脱转现象，运行转数不稳定。

四级电机/六级电机动力对比： 

四级  18.5千瓦电机--117N/M（牛/米）
                                             N（转速）=60f/p                    
                                                             =60*50/(4/2)                  
                                                             =1500r/min  

                                             T（扭矩）=9550*P/N                                          
                                                            =9550*18.5kw/1500r/min  
                                                            =117N/M


六级  15千瓦电机--143N/M（牛/米）
                                             T（扭矩）=9550*P/N                     
                                                             =60*50/(6/2)                  
                                                             =1000r/min  

                                             T（扭矩）=9550*P/N                                          
                                                            =9550*15kw/1000r/min 
                                                            =143N/M
