Product overview
Series overview
The 80ST series is designed for motion control with a compatible servo drive. Rated power, voltage, current, speed, rated torque and peak torque are listed by model below. Peak torque is not a continuous torque rating.
Specifications by model
| Model | Power (W) | Voltage (V) | Rated current (A) | Rated speed (rpm) | Rated torque (N·m) | Peak torque (N·m) | Shaft diameter (mm) | Length: no brake (mm) | Length: PM brake (mm) | Length: EM brake (mm) | Weight (kg) | Line resistance (Ω) | Line inductance (mH) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 80ST-M01330 | 400 | 220 | 2 | 3000 | 1.27 | 3.8 | 19 | 124 | 178 | 164 | 1.78 | 4.44 | 7.93 |
| 80ST-M02430 | 750 | 220 | 3 | 3000 | 2.39 | 7.1 | 19 | 151 | 205 | 191 | 2.9 | 2.88 | 6.4 |

Mounting and configuration
Nominal flange 80mm; pilot diameter 70mm; shaft diameter 19mm; shaft extension 35mm. Mounting pattern shown in the catalog: Ø90 / 4 × Ø6. Body length depends on model and brake option; refer to the no-brake, permanent-magnet-brake and electromagnetic-brake columns. A dash indicates data not provided by the catalog.
Wiring guidance
Motor power and protective-earth terminals are marked U, V, W and PE. The catalog provides 15-pin incremental-encoder and 7-pin absolute-encoder connections. Pin assignments may vary by frame; verify the selected model drawing rather than applying another model’s wiring.
Operating precautions
- Ambient temperature −20 to +40°C; relative humidity below 90%, without condensation.
- Do not strike the shaft when fitting or removing components. Minimize shaft-seat vibration to protect the bearings.
- Brake, gearbox and absolute-encoder options can be confirmed on request. Power, line resistance and line inductance are transcribed from the catalog. Voltage values are rated values; confirm the supply type with the matching drive.
Frame sizes in this family share representative servo-motor visualizations. Actual appearance, connectors and dimensions are defined by the approved drawing.
Product features
Feedback options
catalog encoder rating of 2500 PPR, with absolute-encoder options subject to confirmation.
Brake configurations
optional brakes change body length; verify mounting space before ordering.
Factory support
shaft, cable and matching-drive requirements reviewed with engineering after-sales assistance.
