Internal Product Review
The PBM423FGGE20 is a Sanyo Denki servo motor with a 1:20 gear ratio and 0.25° maximum backlash, giving precision indexing applications a very controlled feel. Encoder feedback at 2000 P/R and a 37.5 kHz maximum response frequency support crisp command tracking and stable tuning behavior. For compact motion systems, the 1.47 N·m allowable torque makes this unit an especially capable choice.

Product Description:
The PBM423FGGE20 is a servo motor with an integrated planetary gearbox manufactured by Sanyo Denki for the PB SANMOTION Servo Motors series. By combining a compact 42 mm frame with feedback electronics, the assembly delivers closed-loop rotary motion for pick-and-place heads, miniature actuators, and indexing tables common in electronics and light-assembly lines. Its role in industrial automation is to translate low-voltage drive commands into precise, repeatable shaft rotation that can be synchronized with sensors and downstream mechanisms.
The transmission stage provides a reduction ratio of 1:20, so one output revolution requires twenty motor revolutions and multiplies shaft torque to 1.47 N·m under rated conditions. Position is monitored by a 2000 P/R incremental encoder, giving 0.18° of basic resolution before interpolation. Servo loops can accept feedback updates up to a maximum response bandwidth of 37.5 kHz, supporting stiff velocity control during rapid indexing moves. All logic and sensor circuits operate from a single 5 VDC ±5% supply, allowing direct connection to typical microcontroller- or FPGA-based motion cards without auxiliary regulators.
The mechanical envelope stays minimal even with the gearhead attached; the unit has a 42 mm square frame and an overall length of 87.9 mm. With a mass of only 0.48 kg, the unit can be mounted on moving carriages while keeping system inertia low. Gearbox backlash is limited to a maximum of 0.25°, which, together with a rotor inertia of 0.056 × 10⁻⁴ kg·m², supports crisp stop-and-hold behavior. Shaft bearings withstand a radial load of 20 N and a thrust load of 15 N, and insulation resistance remains at least 100 MΩ when tested at 500 VDC. The enclosure carries an IP40 rating for basic dust protection, and the output shaft turns in the reverse direction relative to the motor’s electrical phase sequence.
