1.1YBZE, YBZSE Series lifting flameproof electromagnetic brake three-phase asynchronous motor (motor) is mainly used for various types of explosion-proof electric drive of the lifting machinery. Having a a larger overload and high mechanical strength, so it is particularly applicable to those for short-term or intermittent operation, frequent starting and braking equipment. YBZE YBZSE series motor has a disc brake, the motor having a good braking effect. The explosion-proof motor performance in line with GB3836.2-2000 explosive gas atmospheres - electrical equipment - Part 2 flameproof "d" provisions, made? ? Of flameproof explosion-proof mark Exdll the BT4 and Exdll CT4 two kinds. Apply to booster capable of not higher than IIB or IIC, detonated temperature class T1 to T4 group of flammable gas or vapor and air to form explosive mixture.
YBZE series lifting flameproof electromagnetic brake three-phase asynchronous motor can be derived on the basis of YBZPE series crane and metallurgical flameproof electromagnetic brake VVVF three-phase asynchronous motor.
1.2 motor protection class and cooling method
1.2. 1 motor enclosure protection class IP44 according to need can be made of IP54, protection class IP54 junction box.
1.2. 2 Motor cooling method: 112 to 132 frame size for IC410; 160 250 machine short frame sizes IC411.
