YBBP Series Three Phase Flameproof Asynchronous Variable Frequency Adjustable-Speed Motor

YBBP series explosion-proof variable frequency adjustable speed motor is the basic series of fully enclosed,strong refrigeration,squirrel-cage,flameproof variable frequency speed regulating three-phase asynchronous motors developed by our company on the basis of referring to the unified design of the industry,which can realize stepless speed regulating within the range of 100~3550 RPM and wide range of speed regulating.

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. It can realize stepless speed regulation in the range of 100~3550 rpm, with a 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.

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.

YBBP Series Three Phase Flameproof Asynchronous Variable Frequency Adjustable-Speed Motor Structural Description

YBBP series of flameproof frequency conversion three-phase asynchronous motor using computer-aided design, the motor can adapt to SPWM and PWM frequency power supply

The design of the stator, rotor slot and stator winding distribution made a special consideration in order to obtain a more appropriate inductance value, to suppress and reduce the adverse effects of harmonics.

The motor’s electromagnetic load design takes into account a certain margin, both to ensure that the motor at high frequencies when the overload capacity and low frequency operation to maintain constant torque output. In addition, the motor insulation system uses a wide range of internationally used F-class insulation system, reliable insulation, excellent performance.

The motor is forced to ventilate with a separate axial fan to ensure that the motor has a good cooling effect at different speeds.
