The YBBP series explosion-proof variable frequency speed regulation three-phase asynchronous motor is a specialized explosion-proof three-phase asynchronous motor for frequency converters. It adopts computer-aided design and fully considers the impact of variable frequency power supply in the motor. It can be matched with various frequency converters at home and abroad to form an AC speed regulation system. This series of motors has the characteristics of high efficiency, wide speed range, high precision, smooth operation, and convenient operation and maintenance.

Application conditions
⑴ The altitude shall not exceed 1000m.
The ambient temperature should not exceed 40 ℃, with a minimum of -15 ℃.
The motor protection level is IP55.
Relative humidity: not exceeding 90% (below 20 ℃).
⑸ Working system: SI continuous.
Insulation level: F (or H) level.
The rated voltage of the motor is 380V, and the frequency is 50Hz at 660V. The voltage and frequency of additional points can also be determined according to user needs. The frequency conversion range is 1-100Hz. 1-50Hz is constant torque speed regulation, while 50-100Hz is constant power speed regulation.
(8) Explosion proof grade: Explosion proof type Exd Ⅰ, suitable for underground coal mines (non mining working faces); ExdIIBT4, Suitable for hazardous areas with explosive gas environments in factory IIA and IIB levels, temperature groups T1 to T4.
