YG、YGEJ系列三相异步电动机

YG系列辊道用三相异步电动机

YG SERIES THREE PHASE ASYNCHRONOUS MOTOR USED IN THE ROLLER WAY

YGEJ系列辊道用制动三相异步电动机

YGEJ SERIES THREE PHASE ASYNCHRONOUS MOTOR WITH BRAKE USED IN THE ROLLER WAY

  YG系列辊道用三相异步电动机采用封闭自冷式结构,是取代JG2系列电动机的更新换代产品。YG系列电动机按用途可分为YGa和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,适用于单独动冶金工业的传动辊子。

  YG系列电动机额定电压380V,额定频率50Hz,电机采用Y接法,可以满压起动。在保持电压与频率成正比变化的条件下,YGa型电动机允许在40Hz~70Hz范围内使用(但堵转转矩和动态常数随频率变化而变化),YGb型电动机可以在10Hz~70Hz频率范围内作恒转矩调速运行。YG系列电动机安装尺寸符合IEC标准,外壳防护等级为IP54,冷却方式为IC0041。YGa型电动机采用H级绝缘,YGb型电动机中心高112mm~200mm,采用F级绝缘,中心高225mm采用H级绝缘。YGa型电动机主要用于断续工作制,按表1中的堵转转矩和相应于一定的负载持续率进行选用,负载持续率FC表示,分为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,按表2的额定功率选用。

  YGEJ系列电动机是由YG系列电动机附加交流制动器组合而成。交流制动器无整流二极管,由三相380V电源直接供电,具有运行可靠,使用寿命长,制动速度快,定位准确,制动力矩可以从零调到需要值等优点。

  该系列变频电机中交流制动器经国家专利局审批获得专利。专利号:97206492.3

  本系列变频电机可以按用户提供的图纸设计并制造。


YG Series 3-Phase Asynchronous Motor Used in the Roller Way adopts the self cooling construction, which replaced the pervious generation of JG2 series motors. This series motor can be divided into two sub-models, namely, YGa and YGb according to their usage. The YGa series motor is suitable for driving roller of the roller way in the metallurgical industry,as it has a large braking torque, high dynamic constant, soft mechanical performance, and suitable for frequently starting, stopping and inverting capacity. The YGb is used for driving the conveying roller in single direction in the metallurgical industry, due to it features large power, high efficiency and hard mechanical performance.

YG series motor is capable to start under normal voltage condition; therefore it is not necessary to reduce starting voltage, eg. It can be started at 380V and 50Hz. Under condition of the voltage changing in the positive proportion to the frequency, the YGa series motor is allowed to operate freely at range from 40Hz to 70Hz, while the braking torque and dynamic constant varying correspondent to the change of the frequency. The YGb series motor is capable to operate in variable speed and constant torque within the frequency range of 10Hz to 70Hz.

The mounting dimension of the YG series motor meets the IEC Standard. The protection for its outside layer is IP54, and cooling method is IC041. YGa adopts Class H insulation. However, YGb uses Class F insulation for frame height between 112mm to 200mm while Class H insulation for frame height of 225mm.

YGa series motor mainly operates non-continuous duty. Its duty cycle can be selected from one of duties corresponding to the braking torque shown in the table below. The ratio of duty cycle is represented as FC. It can be specified in 15%, 25%, 40% and 60%, among those ratio 40% is considered as the basic cycle. YGb series motor mostly operates under continuous duty. The selection of its duty cycle demonstrated in the table below.

Compared with YG Series 3-Phase Asynchronous Motor Used in the Roller Way, YGEJ Series 3-Phase Asynchronous Motor with Brake Used in the Roller Way has the same features and functions as YG series motors, but it is added a build-in AC brake. The AC brake is powered directly from a three phase power supply without rectified diodes. The AC brakes are not only quick response braking (100 times quicker than a DC single phase brake) but also have improved reliability and long service life. The advantages of AC brakes also include precise positioning, such as no axial movements, and the capability of a wide adjustable range of braking torque, such as from zero (0) to any desired values. The AC brake is an approved patent from the National Patent Bureau. The approval patent number is: 97206492.3.

Above series motors are available in the direct connection between the motor and the gearbox. Please refer to tables below for details.

These series motors can be customized designed and produced to meet your request.
