If you are interested in our products, please contact us in time for a more comprehensive solution!
YBBP series flameproof frequency control and timing three-phase asynchronous motors, its explosion-proof performance meets the requirements ofb GB38361-2010" Explosive environment Part 1: General requirements of equipment" and GB38362-201 0 "Explosive environment Part 2: Equipment protected by flameproof endosure"d". As general driving force, are suitable for flammable gases containing certain components or explosive mixtures of steam and air. The motor can be matched with all kinds of frequency conversion devices at home and abroad. The speed control system consists of energy-saving economy, wide speed range, strong overload capacity and good low-speed performance. It can be widely used in petroleum, chemical and other industries.
The motor is equipped with a separate flameproof axial fan as the cooling air source to ensure the temperature rise of the motor at low frequencies.
The motor can also be equipped with auxiliary equipment such as winding temperature sensor, bearing temperature sensortemperature transmitter and heater according to user needs.
