                            Frame Size: H355~H450

                            额定功率:250~900kW

                            Rated Power: 250~900kW

                            极数:4~8

                            Poles: 4p,6p,8p

                            防护等级:IP54

                            Protection Degree: IP54

                            绝缘等级:F

                            Insulation Class: F

                            额定电压:380V660V

                            Rated Voltage: 380V660V

                            变频范围:恒转矩:25~50Hz

                            Frequency range: constant torque: 25~50Hz

                                      恒功率:4p50~75Hz

                                            constant power: 4p: 50~75Hz

                                            6~8p50~100Hz

                                                        6~8p: 50~100Hz

                            外形及安装尺寸同Y3低压大功率电机

                            Mounting dimensions are same as Y3 big power series

                            因独立风机电机的长度增加ΔL

                            Motor length increase by ΔL because of cool fan



                            结构特点  Structural characteristics               

                              YVF3 系列电动机采用高强度铸铁结构,具有可靠性高、调速范围宽、精度高等特点,装有独立的冷却风机,保证电机在不同转速下均有良好的冷却效果。
                                   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.
