Variable frequency adjustable speed explosion-proof motor

YBBP series flameproof frequency conversion speed regulation three-phase asynchronous motors are suitable for power driving in underground coal mines (non-mining faces) and workplaces containing explosive gas mixtures in factories. The motors are matched with frequency conversion devices and are characterized with sound speed regulation performance, energy saving, large temperature rise margin, long life, good performance, low noise, advanced explosion-proof structure, high reliability, convenient use and maintenance etc. In addition, its speed is adjustable by changing the frequency and has wide speed regulation range. Under the condition of open-loop U/f control, it can realize 5~50Hz constant torque speed regulation and 50~100Hz constant power speed regulation. Under the condition of vector control, the speed regulation range can be expanded, and the overload capacity is strong. What’s more, it can withstand the 160% overload of rated torque for 1min. YBBP frequency conversion speed regulation three-phase asynchronous motor is widely used in light industry, textile, chemical industry, petroleum, metallurgy, machine tool, water pump and other industries. An independent cooling fan is equipped in the electrical rear of YBBP series motors. The installation size of YBBP series flameproof variable frequency speed three-phase asynchronous motors is the same as that of YB2 series motors. This series of motors comply with the national standards GB3836.1 "Explosive Environment Part 1: General Requirements for Equipment" and GB3836.2 "Explosive Environment Part 2: Equipment Protected by Flameproof Shell" d. The electrical performance conforms to the provisions of JB/T 11201.1-2011 "Technical Conditions for Flameproof Variable Frequency Speed Regulation Three-Phase Asynchronous Motor Part 1: YBBP Series Flameproof Variable Frequency Speed Regulation Three-Phase Asynchronous Motor (Machine Block No. 80~355)" and Q/320205BABD14-2012 "YBBP Series Flameproof Variable Frequency Speed Regulation Three-Phase Asynchronous Motor (Machine Block No. 80~450. The power grade and installation dimensions of this series of motors conform to the International Electrotechnical Commission (IEC) standards.
