ВАО series Asynchronous explosion-proof motors
Asynchronous explosion-proof ВАО series motors powered by three-phase 50 or 60 Hz AC mains are designed to drive compressors, pumps, fans, blowers and other mechanisms in a continuous operation mode S1. These motors are used to transport hydrocarbons and other gases and liquids in mines with gas and dust hazard as well as in explosion hazard areas indoors classified as having category 1, 2, 3 and group T1, T2, T3, T4 (as per Electrical Code classification).
The motors have one cylindrical shaft end as per GOST 12080-66 and are delivered in set with splines that comply to GOST 23360-78. The connection with the drive mechanism is realized by means of gear or flexible pin couplings. The shaft end can be made with no spline.
Two versions of motors are available: with right-hand and left-hand rotation. The terminal boxes are located on the right or left side, respectively.
The motors can be started directly from power mains (direct start) or using soft starters and frequency inverters. The use of soft starters and frequency inverters must be coordinated with Manufacturer.
Optionally the motor can be fitted with bearing temperature sensors and stator winding temperature sensors, which can be connected to automatic control systems. Vibration sensors can also be installed in order to monitor the vibrations.
