二、风向:常规产品为吸风式（S），空气从电机向风罩流动。如需吹风式（B），请客户说明。
Wind Direction:Ordinary products adopt the suction type(S).The air flows to the mesh enclosure from the motor.lf the blowing type products are required,please specify
三、常规产品引出线长0.8-1m，如需特殊长度或需要安装接线盒，请客户说明。
For ordinary products,the length of the outgoing line is 0.8-1m.lf the special length is required or the terminal box is required to be installed,please specify specifications are required,please specify.
四、风机风叶直径175-800mm，输出功率40W-1800W，如需加大功率或者特殊规格产品，请客户提出。
The fan has ablade diameter of 175-800mm,with the output power of 40w-1,800w.lf the power is required to be increased or the products with special specifications are required,please specify.
五、使用电压:YWF系列为外转子电机常规产品:单相为异步电容运转的设计，电压有120V，60HZ，220-240V，50/60HZ；三相异步电机标准电压为380V，操作电压范围最高可至440V，频率50/60HZ，或者根据客户特殊要求定制。
Applicable Voltage:YWF series products are ordinary out rotor motor products.The single-phase product adopts the asynchronous capacitor-run design mode,with the applicable voltage of 120V,60HZ or 220-240V,50/60HZ;the three-phase asynchronous motor’s standard voltage is 380V.The maximum operating voltage is 440V.The frequency is 50/60HZ.products can be customized according to the special requirements of the customers.
六、电机温升为风机在零静压时测得，出厂时，一般风机温升控制在50K以下，电机防护等级IP54，绝缘等级B、F、H可供客房选择。电机绝缘等级为B级时，适应环境温度为-40℃-+60℃;电机绝缘等级为F级时，适应环境温度-40℃-+75℃。
The temperature rise of the motor is measured when the fan is under the zero static pressure.When leaving the factorym,the fan’s temperature rise is usually controlled to be below 50K.The protection grade of the motor is IP54.The insulation class has three types like B,F and H, available for selection by customers.The motor with the insulation class of Bcan be operated under the environmenta temperature of -40℃-+60℃；the motor with the insulation class of F can be operated under the environmental temperature of -40℃-+75℃.
七、单相电机内安装热保护器，为B级或者F级，三相则无热保护器，如需要请说明。
The singe-phase motor is equipped with the thermal protector.The protection grade is B or F.The three-phase motor is not furnished with the thermal protector.If the thermal protector is required to be installed,please specify.
