《邮@.com》4T3R7GB型号变频器。因为变频器正反转次数较多,且负载较重,考虑变频器容量放大一档。
(3)动态效果:实现电机参数动态调谐,起动力矩大,控制精度高,快速加减速可调。动态调谐后,电机参数输入变频器中央处理器,保证运行参数高度匹配。
(4)行业功能:全自动洗衣机所完成的初洗、洗涤、漂洗、漂白、脱水等功能,都由变频器多功能端子最多15段速度控制,完美配合时序控制器实现。
(5)保护功能:变频器保护功能完善,实现工业洗衣机电机的欠压、过压、过流、过载、输出短路等全面保护。适当降低电机过载保护系数,提高电机保护精度。
(6)静态运行:变频器控制电机最高运行频率为140HZ,整个静态运行过程平稳,运行电流在变频器额定电流范围内随负载变化合理波动。
(7)节能效果:整个洗涤阶段,随着变频器的频率自动调节而实现无中间过渡(变速箱、变速装置或联轴器、离合器等)装置的无冲击恒转矩变速(无级调速),使洗涤过程的能耗得到明显下降。
