Product Specifications

Technical details and manufacturing context for Drive Motor (Hydraulic/Electric)

Definition
The Drive Motor (Hydraulic/Electric) is a core component of a Motion System, responsible for generating the rotational force required to move mechanical parts. Hydraulic versions use pressurized fluid to create torque, while electric versions use electromagnetic principles. It serves as the primary power source for actuating conveyors, robotic arms, positioning stages, and other moving elements in industrial machinery. This motor is available in two main variants: hydraulic and electric. Hydraulic motors convert the flow and pressure of hydraulic fluid into rotational mechanical energy via pistons, gears, or vanes. Electric motors convert electrical energy into mechanical energy through the interaction of magnetic fields generated by stator windings and rotor currents (induction) or permanent magnets (brushless DC). Typical specifications include rated power from 0.75 to 250 kW, rated speed from 500 to 3000 rpm, operating voltage (for electric) from 220 to 690 V AC, operating pressure (for hydraulic) from 1.0 to 1.6 MPa, maximum torque from 5 to 500 N·m, efficiency from 85% to 95%, insulation class F to H, protection rating IP54 to IP65, operating temperature from -20 to 60 °C, noise level from 60 to 85 dB(A), weight from 10 to 500 kg, and shaft diameter from 20 to 80 mm. These values are reference ranges and must be confirmed for the specific model and application. Standards such as IEC 60034-1, IEC 60038, ISO 19347, IEC 60034-2-1, IEC 60085, IEC 60529, ISO 1680, and ISO 775 are referenced for verification. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.
