I. Characteristics and the use scope

FBZD、FBZDY粉尘防爆型三锥形转子异步电动机，防爆标志DIPA20TAT4适用于20区，T4温度组别及以下防爆场所, FBZDS粉尘防爆型三锥形转子异步电动机，防爆标志DIPA22TAT4,带有自动刹车装置,在电源切断时,依靠转子上压力弹簧产生摩擦转动可使用电机在短时间停止转动,这类电机起动力矩大,常用在起重运输机械中,也可用于自动控制流水线上或特殊的机床设备,要求能迅速制动的工作场所.

The FBZD,FBZDY dust protect motor of taper rotor , marking DIPA20TAT4 is applicable to zone 20 and temperature degree T4 and below environment filled with combustible dust . ,FBZDS dust protect motor of taper rotor , marking DIPA22TAT4.The motor have automatic brake device, at the power supply cut off, depend on to the pressure spring in the rotor creation rubs make the motor stop in short time. This motor with big start-up moment, commonly use in hoisting equipment & transport machine, also can used for the special machine tool equipments or the automatic control line, request can make the brake quickly.

二、适用范围

II. Applicability

1、粉尘防爆型三相锥形转子异步电动机使用于工作环境温度－30～＋40摄氏度，海拨不超过1000米的场合。

1. The dust protect motor of taper rotor is used in environment temperature -30～+40℃, Altitude under 1000m.

2、防爆电动机的电源为三相正弦交流电，额定频率为50Hz，额定电压为380V。（特殊要求可单独设计，如50Hz415V、60Hz220/380V、60Hz220/440V等等）。当防爆电动机接线端的电压不低于额定值的90％时（频率为额定值），隔爆电动机仍能正常工作。

2. The power of the dust protect motor of taper rotor is three phase alternating current of sine , rated frequency is 50Hz ,rated voltage is 380V ,(The special request can singleness design , such as 50Hz415V、60Hz220/380V、60Hz220/440V).When the terminal voltage not less than 90%(the frequency is rated),the motor can well-balanced operate .

3、防爆电动机的工作制度为JC25％，绝缘等级为F级，符合GB12476.1-2000《可燃性粉尘环境用电气设备 第1部分：用外壳和限制表面温度保护的电气设备》以及JB/T9008.3-1999.

3. The working restrict of the dust protect motor of taper rotor is JC25% .the insulation grade is F , According as the national standard GB12476.1-2000《 Electrical apparatus for use in the presence of combustible dust—part 1: Electrical apparatus protected by enclosures and surface temperature limitation 》ａnd JB/T9008.3-1999.
