YBBP Series Flameproof Three-phase Asynchronous Motors Used in Underground Coal Mines

technical superiority

This series of flameproof variable frequency speed regulating three-phase asynchronous motors adopts flameproof axial fan for forced ventilation, and the independent fan is not limited by the motor speed, which can not only ensure the constant power operation of the motor at high frequency, but also maintain constant torque output at low frequency. Explosion-proof mark: ExdⅡ BT4 Gb, which can replace Exd Ⅱ AT1Gb, Exd Ⅱ AT2 Gb, Exd Ⅱ AT3 Gb, Exd Ⅱ AT4 Gb, Exd Ⅱ BT1 Gb, Exd Ⅱ BT2 Gb and Exd Ⅱ BT3 Gb. The speed regulation system composed of it and frequency converter is the best choice for speed regulation and energy saving, which can realize smooth stepless speed regulation with remarkable energy saving effect and high speed regulation accuracy.

Operating conditions

Ambient air temperature:-15℃ ~+40℃; Altitude: ≤ 1 km; Monthly average ambient air humidity (when the temperature is 25℃): ≤ 90%.

Product features
