HARMONIC DRIVE FHA-32C-50-H-C1024-SP

Product Short Description

Product Name: Harmonic Drive FHA-32C-50-H-C1024-SP Hollow-Shaft Integrated Servo Actuator

Product Introduction: The FHA-32C-50-H-C1024-SP is part of Harmonic Drive’s FHA-C series of ultra-flat, integrated hollow-shaft rotary servo actuators. It combines a precision Harmonic Drive gear component with a performance-matched brushless servo motor and an incremental encoder in a single compact cylindrical body. The “C1024” suffix denotes a 1024-line incremental encoder, “H” denotes an IP65-rated housing for washdown environments, and “SP” indicates the standard brakeless configuration.

Structural & Working Principle: The actuator uses a zero-backlash harmonic gear mechanism — a wave generator, flexspline, and circular spline — to achieve high reduction in a compact form. The central hollow shaft allows cables, tubing, or laser beams to pass through the axis of rotation. The brushless servo motor is driven by third-party servo drives or Harmonic Drive’s DDP (CANopen), RTL, REL (EtherCAT), or HA-800 series drivers.

Functional Features:

Zero backlash, high torsional rigidity
Compact cylindrical design with large center through-hole
IP65 protection for washdown, oily, and harsh environments
High torque density relative to size
Closed-loop high-precision positioning via incremental encoder

Application Scenarios: Semiconductor manufacturing equipment, robotics joints, rotary indexing tables, medical equipment, packaging machinery, and any application requiring high torque, zero backlash, and routing of utilities through the rotation center.

Installation Requirements: Flange-end direct locking with standard mechanical mounting holes. Ensure the hollow shaft aperture is aligned for cable/tube pass-through. Connect to a compatible 200 VAC servo drive. Ambient temperature must be maintained within 0 to +50°C unless a wide-temperature variant is specified.

Usage Precautions: The SP configuration has no built-in brake — for vertical or holding applications, select a variant with the “B” (brake) option. Do not exceed peak torque or maximum output speed. Ensure proper encoder wiring to avoid counting errors.
