The YBZ and YBZD series explosion-proof three-phase asynchronous motors for lifting and the YBZE and YBZDE series explosion-proof electromagnetic braking three-phase asynchronous motors (referred to as motors) for lifting are mainly used for electric drive of various types of explosion-proof lifting machinery. It has a large overload capacity and high mechanical strength, making it particularly suitable for equipment that operates for short or intermittent periods, frequently starts and brakes. The YBZE and YBZDE series motors are equipped with disc brakes, which provide excellent braking performance. The explosion-proof performance of the electric motor complies with the provisions of GB3836.2-2000 Electrical Equipment for Explosive Gas Environments Part 2 Explosion proof Type "d", and is marked with two types of explosion-proof marks: Exd Ⅱ BT4 and Exd Ⅱ CT4. Suitable for places where explosive mixtures of flammable gases or vapors with air are formed, with a detonation temperature group of T1~T4 and a transmission capacity not higher than level IIB or IIC.
