YYB Series Three-Phase Asynchronous Oil Pump Motor is a mechanical-electrical integrated product specifically designed for hydraulic systems. Featuring an internal shaft structure that enables direct connection with hydraulic pumps without couplings, it boasts characteristics such as compact structure, small size, light weight, minimal vibration, low noise, high efficiency, and long service life.
\n**Product Overview**
\nThis series of motors is an ideal power solution for hydraulic system drives. Direct connection with axial piston pumps, gear pumps, vane pumps, etc., forms oil pump motor units. Compared to traditional motor pump assemblies, it eliminates couplings, pump bases, and common base plates, reducing axial length by approximately 25% and minimizing installation space while ensuring smoother operation.
\n**Technical Parameters**
\n– Frame size: 90\uff5e280
\n– Power range: 0.37kW\uff5e90kW
\n– Working system: S1 (continuous duty)
\n– Insulation class: F
\n– Protection class: IP54\/IP55 (partial models)
\n– Cooling method: IC411
\n– Voltage: 380V (customizable 110-660V)
\n– Frequency: 50Hz\/60Hz
\n**Application Fields**
\nWidely used in hydraulic transmission machinery such as machine tools, forging equipment, lifting devices, shipbuilding, injection molding machines, metallurgy, construction machinery, and mining equipment. Suitable for motor integration with CY-Y pump units, gear pumps, vane pumps, and other types of piston pump assemblies.
\n**Product Features**
\n– **Structural Advantage**: Direct pump-motor connection ensures high concentricity, smooth operation, low noise, and extended lifespan.
\n– **Installation Convenience**: Simplified user selection process by adhering to B34 asynchronous motor connection standards, eliminating the need to consider pump installation dimensions.
\n– **Space Efficiency**: Compact design reduces installation space and layout complexity.
\n– **Reliable Performance**: High starting torque, low starting current, high slip rate, and soft mechanical characteristics.
\n– **Comprehensive Certifications**: Passed China Compulsory Certification (3C) and CE safety certification.
\n**Operating Conditions**
\n– Ambient temperature: -15\u2103\uff5e+40\u2103
\n– Altitude: \u22641000m
\n– Power supply: Voltage fluctuation \u00b15% (short-term \u00b110%), frequency fluctuation \u00b12% (short-term \u00b15%)<\/p>","protected":false},"excerpt":{"rendered":"
