YP, YPKK Series (H710~800) large-size High Voltage Variable Frequency Motor

　　结构特点  Structural characteristics
　　该系列电动机采用箱式钢板结构，采用高压变频器供电以达到无极调速的功能，电机通风罩或冷却器采用强制风冷的结构，确保电机在低频运行状态下的通风散热；电机轴承设计为端盖式滑动轴承，采用稀油站强迫润滑。当电机功率超过2000kW时，可根据用户要求，多配一副出线盒，用于引出三相绕组中的中性点。该产品具有高效节能、低噪音、振动小、调速范围广、精确度高和高可靠性等优点，可驱动各种通用机械如风机、水泵、压缩机、矿山机械等，被广泛应用于电站、钢厂、矿山等工矿企业中。
This series motors with box type steel structure, can be ajusted its speed using high voltage inverter; Forced cooling structure for the cooler or protective cover, ensure the cooling effect of motor under low frequency operation; Sliding bearing is installed and forced lubricated by lubricating station. When the power is more than 2000kW, according to the requirement of customer, another terminal box can be installed to pick up the neutral point of winding.
This series motors have characteristics of high reliability, wide speed range, high precision, beautiful apperance, low noise, little vibration, and can be applied to fan, pump, compressor, mining machinery, engineering machinery installed in 　power plant, steel mill, mine and so on.insulation, moisture-proof and shock resistance; Temperature senor for stator and bearing, non-stop oil filling and exit pipe, improve the protection ability and operation efficiency of the motors.
该系列产品适用于：1、较大的启动转矩；2、输电线路容量不足以启动鼠笼型电动机；3、启动时间长和启动较频繁；4、需要小范围调速。
This series motor can be applied to the requirements as follows: 1. The lager starting torque; 2. Power capacity is not enough to start a squirrel cage motor; 3. Long start time or start more frequently; 4. Adjust speed in a small range.
