技术特点Technical Features：

YBU，YBUS, YBUD系列是水冷型煤矿井下掘进机用电机，YBU，YBUS 为单速，YBUD为4/8极双速。针对掘进机的结构特点，通过巧妙的设计，使得电机在完成驱动功能的同时，还可作为掘进机的一个重要结构件，从而简化、紧凑了掘进机的结构。                                                          

YBU，YBUS, YBUD series motors are equipped with water-cooling system and applicable to the tunnellers under ground in coal mines. YBU, YBUS are of single speed, YBUD are of double speed with 4/8 pole. The special design complied with the construction features of the tunnellers make the tunnellers more compact.

电机定子绕组采用VPI整浸工艺，转子采用中频焊接、热套工艺；可设置绕组温度、轴承温度监控、过载保护装置，使设备运行更加可靠。

The winding of the stator is wholly varnished with VPI technology. The intermediate frequency welding technology and the hot sleeve technology have been adopted in making the rotor. The motor can also be equipped with winding temperature, bearing temperature, overload protection monitor devices so that the reliable operation of the motor can be guaranteed.

电机采用钢板焊接机壳，结构紧凑，坚固耐用，冷却效果好，方便了井下使用。

The frames of the motors are welded with steel plate. The structure of  the frame are compact, firm and have excellent cooling effect, that is convenient to be used in coal mines.

电机引进了西门子先进的模块化设计理念，丰富的选件订制，能够满足客户的各种特殊需求。

With the advanced modular design concept and flexible options, the motors can meet the customer’s various requirements.
