                              恒功率:4p50~75Hz

                                    constant power: 4p: 50~75Hz

                                    6~8p50~100Hz

                                                6~8p: 50~100Hz

                    外形及安裝尺寸同Y3低壓大功率電機

                    Mounting dimensions are same as Y3 big power series

                    因獨立風機電機的長度增加ΔL

                    Motor length increase by ΔL because of cool fan



                    結構特點  Structural characteristics               

                      YVF3 系列電動機采用高強度鑄鐵結構,具有可靠性高、調速范圍寬、精度高等特點,裝有獨立的冷卻風機,保證電機在不同轉速下均有良好的冷卻效果。
                           The Y2VF series motors with high strengh cast iron structure, have the characteristics of high reliability, wide speed range, high precision. The Y2VP series motors have independent cooling fan to ensure good cooling effect under different speed.
