Features:
- 20:1 planetary reduction: Pairs the documented speed ratio with a coaxial output path.
- Defined load capability: Publishes torque, radial-load, axial-load, and speed limits.
- Motor-specific direct mounting: Uses the Type 3 adapter selected for the 400 motor class.
The complete code fixes ratio, frame, motor class, and adapter type as one reducer configuration.
Mechanical fit alone does not establish acceptable torque, speed, backlash, or shaft loading.
Legacy planning should preserve the motor and driven-machine geometry before the installed reducer is removed.
Apter Power supports NIDEC VRSF-20C-400-T3 quotations, technical documents, and servo-reducer application review.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Torque envelope: Keep continuous and transient demand inside the documented output limits.
- Input speed: Evaluate normal and peak motor speed against the 3000 and 5000 rpm values.
- Backlash: Account for 15 arc-min when the motion profile depends on reversal accuracy.
- Load capacity: Check radial and axial reactions at the actual output-shaft load point.
- Motor interface: Confirm the 400 motor class and Type 3 mounting details before assembly.
- Alignment: Keep motor and reducer pilots clean and concentric during installation.
- Output coupling: Avoid hammering, forced fits, or unsupported overhung loading on the shaft.
- Fasteners: Use the documented tightening sequence and recheck the mounted assembly.
- Ambient temperature: Plan operation within the documented 0 to 40°C ambient range.
- Surface temperature: Investigate loading or lubrication conditions if the housing approaches 90°C.
- Lubrication: Protect the sealed grease-filled assembly from leakage and contamination.
- Ingress boundary: Treat the standard IP40-equivalent construction as indoor protected equipment.
- Servo axis reduction: Increases available torque while reducing motor speed by 20:1.
- Positioning equipment: Supports controlled motion where the published backlash is acceptable.
- Machine retrofits: Maintains a documented VRSF motor and output interface in legacy equipment.
- Automation mechanisms: Drives indexed, conveying, handling, or adjustment axes within rated loads.
