PBM423DHLA20
by Sanyo Denki
The PBM423DHLA20 from Sanyo Denki is a high-precision servo motor in the PB SANMOTION Servo Motors series designed for industrial automation and motion control applications. With a compact 42 mm sq. form factor and a maximum stall torque of 1.47 N·m, this unit delivers reliable power in space-constrained installations. Featuring an optical incremental encoder with a resolution of 16000 P/R, it provides accurate position feedback for demanding precision tasks. The primary function of the PBM423DHLA20 is to enable smooth, high-accuracy motion in robotics, packaging, and assembly lines where repeatability and compactness are essential.
This servo motor supports both single- and three-phase 200 to 230 VAC input supply voltage, ensuring compatibility with common industrial power systems. The integrated 1:50 gear ratio enhances torque output while maintaining a maximum backlash of 0.35 degrees, reducing mechanical play and optimizing positional accuracy. Control is managed via the PB4A002R301 driver model, which interfaces with the motor through a bundled 1 m power cable (PBC8P0010A) and a 1 m unshielded I/O signal cable (PBC5S0010A). The optical incremental encoder is paired with high synchronization algorithms to support steady and smooth operation at an allowable speed of 60 min^-1, ensuring consistent performance under varying load conditions.
Built to withstand rigorous industrial environments, the PBM423DHLA20 operates reliably within a temperature range of 0 to 55 °C and offers an insulation resistance of 10 MΩ min., providing robust electrical protection. Its vibration resistance rating (acceleration: 5 m/s^2, frequency: 10–55 Hz) enhances mechanical durability against shock and resonance. The combination of compact size, high torque density, and precise feedback makes this servo motor an ideal solution for automated machinery requiring efficient, dependable motion control. By integrating the PBM423DHLA20, manufacturing systems benefit from improved throughput, reduced downtime, and enhanced positional accuracy.
