106-4003-2
by Sanyo Denki
The Sanyo Denki 106-4003-2 motor is a precision face-mounted unit from the Super DC Servo Motors series by Sanyo Denki. Boasting a rated power of approximately 2.7 kW, an estimated 200 V DC supply voltage, and a no-load speed of around 3000 RPM, it is engineered to deliver accurate speed and torque control. Its primary function is to provide stable and responsive motion control in demanding industrial automation applications, ensuring consistent performance in assembly, packaging, and machine tool systems.
The 106-4003-2 incorporates a robust face-mounted configuration on a standard Frame Size 106, simplifying mechanical integration into existing assemblies. It draws approximately 12 A under rated load to generate an output torque of around 20 Nm, while achieving an efficiency of approximately 80%. The motor housing is totally enclosed, fan cooled, offering reliable thermal management by forcing airflow over internal windings. Insulation is rated Class F, capable of withstanding temperatures up to 155°C, and the rotor assembly exhibits a moment of inertia of ~0.015 kg·m², which supports rapid acceleration and deceleration. Sealed ball bearings reduce contamination risks and maintenance intervals, ensuring long-term reliability.
Designed for continuous duty within an operating temperature range of -10°C to +50°C, the 106-4003-2 maintains performance under diverse environmental conditions. Its Class F insulation combined with the fan-cooled enclosure protects against heat buildup, while the sealed bearing arrangement enhances durability in dusty or humid settings. Compatibility with standard industrial mounts and power supplies streamlines system design. In industrial automation contexts—such as conveyor drives, robotic positioning, and process control—this servo motor delivers precise speed regulation, high torque density, and extended service life, reducing downtime and operational costs.
