AJAB Sub-Oil A Motor

AJAB Sub-Oil A Motor is a power unit with the motor submerged in hydraulic fluid. It features excellent heat dissipation and insulation, reduced wear and noise, strong adaptability to harsh working conditions, and can drive hydraulic pumps stably.

General Machinery Industry: Hydraulic Pump


This motor is a high-end power unit specifically engineered for general-purpose hydraulic power units; its core technological innovation lies in operating with both the rotor and stator fully submerged in hydraulic fluid. From a thermal management perspective, this architecture completely overcomes the heat dissipation bottlenecks inherent in traditional air-cooled motors. Acting as a highly efficient thermal conduction medium, the hydraulic fluid rapidly absorbs the ohmic heat generated during operation and transfers it to the oil reservoir, ensuring the motor can sustain prolonged operation within the 550W to 3000W power range without experiencing thermal degradation.
In terms of mechanical longevity and acoustic performance, the oil-immersed design provides continuous lubrication, thereby reducing bearing friction. The motor's internal structure eliminates the need for traditional seals, minimizing wear caused by dry friction and resulting in exceptionally low operating noise levels—making it ideally suited for use in laboratories or other indoor environments where low-decibel operation is required. Furthermore, to withstand harsh operating conditions, the motor utilizes specialized oil- and heat-resistant lead wires with an insulation rating of Class B/F, effectively safeguarding the electrical system against fluid-induced corrosion. Its compact physical dimensions (ranging from 158mm to 235mm) and open IP00 protection rating—which relies on the hydraulic system's oil reservoir for secondary protection—establish it as the most stable and reliable power core for integrated hydraulic systems.
