D-Mover D3-K — 3DOF sim-racing motion kit
A compact 3DOF racing motion kit for pitch, roll, and heave. Motion comes from four 48 V drive-integrated linear actuators (DOF count ≠ actuator count). Built for 30 / 40 / 50 series aluminum racing cockpits; other frames via custom mounts. Sold as a motion kit, not a full cockpit rig.
What’s in the kit
- 4 motion linear actuators + mounting accessories
- Power & wiring kit with a standard 8-channel controller — ready for later expansion (D3-K uses 4 channels today)
- SimTools v3 software / plugin path for PC control
Key specs
- Freedom of motion: 3DOF (pitch / roll / heave)
- Actuators: 4 linear, drive-control integrated
- Bus voltage: 48 V DC
- Stroke: 140 mm (5.5 in)
- Linear speed: 240 mm/s (rated)
- Acceleration: Limited to 1G (footnote: max 3G)
- Continuous thrust / actuator: approx. 150 kg
- Continuous max moving load (platform): approx. 300 kg
- Adaptive loading: Standard
- HAPTIC: HAPTIC haptic feedback
- VR: Supports VR motion compensation
- Controller: Standard 8-channel — ready for later expansion
- Wiring: One cable per actuator; order-agnostic blind-mate
- Cockpits: 30 / 40 / 50 series; others via custom mounts
- Occupying area: 1.3 m × 0.8 m
- Power box: 30 × 16 × 12.5 cm; 1500 W supply; average consumption ~120 W; AC 110/220 V in → DC 48 V out; supports 8 axes as a power distributor (drive/control integrated in each actuator)
- Noise: Industry-leading quiet (qualitative; no published dB yet)
Payload footnotes: Continuous figures. Moving mass = driver + seat + frame; four-actuator heave share + firmware 1G limit; not a weighed bench nameplate. Higher short-time capability is not a continuous rating. Peak load kg is not published.
Expand path (channels): D3-K 4 ch → planned dual-seatbelt tensioner 2 ch → Surge / traction-loss chassis module 2 ch (fits the standard 8-channel controller).
Software
Host control via SimTools v3 + D-Mover plugin. Presets for Assetto Corsa and Dirt Rally 2.0; once you know the system, you can modify setups and add configs for other titles.
Why builders choose it
- Racing-first 3DOF kit with clear continuous payload numbers
- Adaptive loading + HAPTIC haptic feedback as standard feature lines
- VR motion compensation supported
- Simple one-cable-per-actuator wiring and a controller already sized for later channels
