Product Description:
The PBM423DXC25 is a Sanmotion Servo Motor designed by Sanyo Denki for compact, precise motion control solutions. This servo motor is used in robotic arms, automated machines, CNC machinery, and precision motion control systems. Its flange dimension is 42 mm which allows easy integration into other machines with space-limited mechanical setups.
The length of the PBM423DXC25 servo motor is 57.6 mm and it uses a single shaft configuration that utilizes a D-shaped output profile. This shaft design enhances coupling accuracy during assembly and ensures the maximum efficiency of torque transmission while minimizing slippage. Thus, it significantly enhances mechanical reliability and operational precision. This servo motor provides a strong maximum stall torque rating of 0.39 Nm. Such torque capacity offers reliable and steady performance despite the compact construction of the motor. The rotor inertia of this servo motor is notably low at 0.056 × 10⁻⁴ kg·m² and enables exceptional acceleration and deceleration capabilities. This servo motor also has an incremental encoder which offers a resolution of 2000 pulses per revolution. The encoder provides accurate feedback on the position which is critical for closed-loop control schemes.
For convenient electrical installation, the PBM423DXC25 servo motor also includes lead wires equipped with connectors. These connectors combine encoder signals and power supply connections to simplify the installation tasks. This servo motor is designed to operate at a standard power supply current of 3 A and achieves good energy efficiency without sacrificing performance. This servo motor is built with extra durability and accommodates an allowable thrust load of 9.8 N. This motor also withstands radial loads up to 49 N. These heavy-duty loading capabilities underscore its mechanical robustness and durability. This servo motor weighs only 0.35 kg and its lightweight design ensures its versatility and easy integration in various systems.
