沈阳同步电机


辽宁同步电机专为驱动矿山磨机设计的大型同步电动机,辽宁同步电机额定参数为额定频率为50Hz额定电压有6000V10000V; 功率因数:0.9(超前);定额为连续宁同步构及安装型式IM7311冷却方法IC0;外壳防级为IP20,通方式开启式自然通或可制成全封管道通式。TDMK系列电动机适于在海拔不超1000m,冷却介温度不超40度。宁同步机励磁系采用可控硅励磁装置。电动机允电压直接起。如用户电网不允电压直接启动时,也可采用降,此时电动机的起动电流与端电压成正比下降,而起动转矩与端电压的平方成正比降低。辽宁同步电机有一个圆柱形轴伸端,其旋转方向应按照指示牌规定的方向旋转,旋转方向由集电环端看一般为逆时针,也可根据要求制成顺时针。电动机和磨机用联轴联接时,电动机轴伸上不能承受外加的径向力或轴向力
TDMK
系列电动机主要适用于传动矿山磨机用的大型交流三相同步电动机。主要传动格子型球磨机、棒磨机、磨煤机等。
TDMK series synchronous motors are designed for driving large-scale synchronous motors of mine mills. The rated parameters of this series of motors are rated frequency of 50Hz; rated voltages are 6000V and 10000V; power factor: 0.9 (leading); the rating is continuous. The structure and installation type is IM7311; the cooling method is IC0; the protection degree of the enclosure is IP20, the ventilation mode is open natural ventilation or it can be made into fully enclosed pipeline ventilation. The TDMK series motors are suitable for use at temperatures not exceeding 1000 m and cooling media temperatures not exceeding 40 degrees. The TDMK series motor excitation system uses a thyristor excitation device. The motor allows full voltage to be started directly. If the user's power grid does not allow full voltage to start directly, a step-down start can also be used. At this time, the starting current of the motor decreases in proportion to the terminal voltage, and the starting torque decreases in proportion to the square of the terminal voltage. The TDMK series motor has a cylindrical shaft extension end, and its rotation direction should be rotated in the direction specified by the sign. The direction of rotation is generally counterclockwise from the end of the collector ring, and can also be made clockwise according to requirements. When the motor and the mill are coupled by a coupling, the motor shaft cannot be extended to withstand external radial or axial forces.
The TDMK series motors are mainly suitable for large AC three-phase synchronous motors used in transmission mine mills. The main transmission lattice ball mill, rod mill, coal mill and so on.
