On the basis of YBZ series explosion-proof three-phase asynchronous motor for lifting, YBZP series explosion-proof variable frequency speed regulating three-phase asynchronous motor for lifting and metallurgy can be derived; On the basis of YBZE series explosion-proof electromagnetic braking three-phase asynchronous motor for lifting, YBZPE series explosion-proof electromagnetic braking variable frequency speed regulating three-phase asynchronous motor for lifting and metallurgy can be derived.

The YBZR series explosion-proof wound rotor three-phase asynchronous motor (referred to as the motor) is 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 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 three types of explosion-proof signs: Exd Ⅰ, Exd Ⅱ BT4, and Exd Ⅱ CT4. Suitable for places where explosive mixtures of methane or coal dust and air are formed underground, and places where explosive mixtures of flammable gases or vapors and air are formed with a detonation temperature group of T1~T4 and a transmission capacity not higher than IIB or IIC level for factory use.
