详细信息
该电动机具有体积小、重量轻、性能好、使用可靠、维修方便等优点。该系列电动机能够在频繁起动、制动、正反转、反接制动等冲击生载荷和高温、多灰尘环境的恶劣条件下连续或断续工作,具有较高的过载能力,为钢厂工作辊道和运输的专用电动机,也可应用于其他机械设备上。
电动机按用途可分为YGa、YGb两种型式。YGa型电动机具有堵转转矩大、动态常数高、机械特性软的特点,能够频繁起动、制动和反转运行,适用于单独拖动冶金工业的工作辊道辊子。YGb型电动机具有功率大、效率高、机械特性硬的特点,通常只有单向运转,适用于单独拖动冶金工业的传送辊道辊子。
电动机额定电压380V,额定频率50Hz,电动机采用Y形联结,可以满压起动。在保持电压与频率成正比变化的条件下,YGa型电动允许在40~70Hz频率范围内使用(但堵转转矩和动态常数随频率的变化而变化);YGb型电动机可在10~70Hz频率范围内作恒转矩调速运行。
YGa型电动机主要用于断续工作制,负载持续率以Fc表示:分别为15%、25%、40%、60%四种,其中40%为基准定额。
YGb型电动机主要用于连续工作制(S1)。

二、结构简介
YG系列电动机采用全封闭结构型式,外壳防护等级为IP54,机壳表面有环形散热筋,冷却方式为IC0041。
YGa型采用H级绝缘,YGb型采用下级绝缘(112~200mm)、H级绝缘(225mm)。
电动机增加了轴承润滑脂再补给装置,采用耐高温润滑剂,加强了机械强度。
电动机的安装型式有IMB3、IMB5和IMB35三种。
电机的接线盒位于机座左侧,从轴伸端看,如用户有特殊要求,要订货时说明,另行商议。
