YBBP series flameproof three-phase asynchronous motor with variable frequency speed regulation
YBBP series flameproof three-phase asynchronous motor with frequency conversion speed regulation meets the requirements of GB3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Environment Part 2: Equipment Protected by Flameproof Shell"d". It is made of flameproof type. The flameproof marks are Ex D II A T4 Gb, Ex D II B T4 Gb.
YBBP series motors are suitable for equipment in places containing combustible gases or explosive mixtures of steam and air. They are general driving forces. Mainly used in petroleum, chemical and other industries, but also in textile, metallurgy, urban gas, transportation, grain and oil processing, paper making, medicine and other industries are widely used, driving pumps, fans, reducers, compressors, conveyors and other transmission machinery.
The motor is equipped with an independent flameproof axial flow fan as cooling air source, which ensures the temperature rise of the motor at low frequency.
The main junction box of the motor is located at the top, and auxiliary equipment such as winding temperature sensor, bearing temperature sensor, temperature transmitter and heater can also be installed according to user's needs.
