AJAB Sub-Oil B Motor

AJAB Sub-Oil B Motor is a power device whose motor is submerged in hydraulic oil. It delivers excellent heat dissipation and insulation, reduces wear and noise, operates reliably under harsh conditions, and drives hydraulic pumps stably.

General Machinery Industry: Hydraulic Pump


The Type B motor is engineered to prioritize high power density and robust torque output. Its power range extends from 1100W to 5500W, with a peak rated torque reaching as high as 37.6 N·m; this capability enables it to drive larger-displacement hydraulic pumps, thereby meeting the demanding industrial requirements of heavy-duty hydraulic clamping, high-tonnage lifting, and similar applications. In terms of electrical stability, the motor performs exceptionally well under an S3-30% intermittent duty cycle, demonstrating the capacity to withstand frequent start-stop cycles and operational shocks without compromising its service life.
Regarding installation adaptability, this motor exhibits a high degree of industrial flexibility. Its 138mm x 138mm square flange design significantly conserves internal space within the hydraulic reservoir, while offering a range of shaft connection options—from a standard Φ30 diameter to various custom configurations—to ensure seamless integration with major domestic and international pump heads. Additional technical highlights include its exceptional insulation reliability; even when operating in complex atmospheric pressure environments at altitudes below 1000 meters, the motor maintains stable electrical connectivity through the use of terminal strips.
