您好，建议您可以了解下苏州星之瑞的伺服改造技术，节能改造工程不只是卖产品这么简单，而且还需要有专业伺服机器改造技术员及改造后的专业使用指导，让您解决所改造机器上相关的一些常见问题。以下是为您解析关于注塑机节能方面的节电原理。
高节能：与定量泵相比电机节能高达 91.7%
与变量泵比电机节能最低50%
1、动能回收系统
内置大容量电容，可将电机快速下降时的动能转化为电能储存起来，下次加速时再次释放，减少制动单元工作频次。
2、点击最佳效率点自动跟随
国内唯一自主研发和生产成套伺服驱动和电机的企业，从设计，研发，生产，调试每个环节确保系统的高效一致，独创的电机最佳效率点自动跟随技术，使伺服系统始终处于高效状态，可以大大提高设备的节能指标。
3、节省了液压油冷却系统的消耗
传统注塑机由于高压节流的存在，油温迅速上升，导致油体变稀、管路软化、漏油等，所以必须对液压油进行强波冷却，这需要消耗相当大的功率。使用星辰伺服后，，绝大多数工况下，在自然冷却下，油温温升小于6℃
高转速、高响应速度使注塑机效率最高提升25%
1、高转速带来高效率
星辰伺服将电机进行恒功率升速，在保持油泵低俗大压力的同时提高油泵排量，普通驱动器只能在额定转速内驱动交流永磁同步电机，同样功率的电机仅能通过降低转矩提高转速，降低了保压压力、若通过提高电流来提高转速，电机就会发热和退磁。
星辰伺服将额定转速1500rpm的电机，通过软件控制，将电机在1500rpm以上恒功率升速到最大可达2200RPM，有效的提高了泵的排量，而并不增加驱动电流，注塑机运行既安全，又迅速。
2、高响应
星辰伺服响应速度快，压力上升时间和流量上升时间快至30ms，提高了液压系统的响应速度，减少了动作转换时间，加快了征集的运行节拍；
1500转加速时间只需要15毫秒，适合做螺杆射速在0-400mm/s的高速机型。星辰伺服已配合注塑机长假生产过实际射速达240mm/s和330mm/s的高速机型，该机型在终端客户处应用良好，节能率达80%。既解决了变量泵爆发力不强的问题，有避免了定量泵的高能耗。
万倍调速比和高响应速度大大提高注塑精度
1、高位置重复精度
星辰伺服的高抗绕动能力和高响应保障了开、合模，射胶终点等位置的重复精度可达到正负0.1mm；配合高响应电脑，多段速度射胶后的射胶重点位置偏差可保证0.1mm
2、高压力控制精度
星辰伺服的高响应，压力闭环控制模式使系统压力非常稳定，稳态，压力波动量低于正负0.2bar，提高了塑料产品的成型质量；适合于在两扳机等精密注塑机上使用。
3、降低产品平均质量
在保证100%的成品率的同时，可降低产品重量，大幅降低原料成本。
广东做伺服改造比较专业的是广东美高，规模比较大，楼主可以关注下
