FPA
The AC Servo Actuator FPA Series combines the precision planetary gear speed reducer HarmonicPlanetary® with a dedicated AC servo motor.
With its flat, thin profile, the FPA Series reduces overall length compared with combinations of orthogonal shaft type speed reducers and servo motors in the same torque range.
The absence of an orthogonal section simultaneously achieves high efficiency and precision.
Expected performance improvements include further miniaturization of semiconductor/FPD manufacturing equipment, robots, machine tools, and various FA equipment, as well as enhanced precision and efficiency for all equipment using orthogonal planetary speed reducers.
In addition to the dedicated HA-900 series driver, it is also compatible with Mitsubishi Electric’s MELSERVO J5 series and Panasonic’s MINAS A6 series.
Features:
- Flat and Low Profile – The HarmonicPlanetary® reducer and flat AC servo motor are coaxially integrated, enabling compact equipment design.
- Low Loss – No orthogonal gear section, reducing energy loss.
- High Stiffness, Low Backlash – Backlash < 1 minute (≤3 minutes for size 11).
- Wide Speed-Torque Range – Ratios from 1/5 to 1/45 for flexible applications.
- 24-bit Absolute Encoder – Supports A-format® communication with multi-turn capability.
- Quick-Lock Connector – Integrated wiring for easy connection.
