DK6+ Motion System
DK6+ Motion System
USA domestic shipping is 3-5 days. All international shipping is typically 5-7 days.
The DK6+ motion system is a 6" (150mm) motion system designed for high travel simulation applications such as off-road racing, rally and flight. The additional stroke allows for better representation of our motion layers with less saturation and hence it also compliments low travel vehicles such as formula cars.
The common saying of "less is more" is really a half-truth. High travel motion systems, if designed well, can better represent the true dynamic nature of vehicle dynamics. The DK6+ however still shares our philosophy of Motion Integrity and does not over-represent certain layers such as pitch and roll which make control input unnecessarily more difficult.
The system shares the same design and construction as our industrial-grade DK-X motion systems used in our full motion vehicle and platform simulators. Additionally, DK6+ is mechanically and electrically engineered around our unique motion algorithm to provide the most realistic and representative vehicle motion feedback with no pre-recorded canned effects.
DK6+ takes a modern approach to signal processing and motion control to create the most responsive system on the market. Every elevation change, vehicle movement, surface change and gear shift, is captured and reproduced within 2” (50mm) of the available mechanical stroke.
The DK6+ was originally created to serve many race and flight simulation centers around the world. The larger Teknic motor is capable of 800 lbs. (360 kg.) of total supported mass and hence can support a larger variety of drivers or exceptionally heavy rigs. The DK6+ is also engineered with a solid steel piston and special dry run bearings for exceptional side loading capability.

Motion Specific Electrical System
Sigma uses premium American-made Teknic integrated motors specifically tuned to run Sigma’s advanced motion algorithms. At double the price of conventional motors, the servos have three times the performance of conventional motors. We are also the only company to feature 75VDC electrical architecture for various performance standards. Each motor is optically isolated guaranteeing zero electrical or magnetic interference. Cable lengths from the controller to the motors can go up to 150-feet and the controller connects via an ethernet cable to the computer for optimal signal integrity. The controller is switchable between 120/240v and ships with power cables and accessories specific to your region.
Specialized Motion Software
Sigma takes a first principles approach with our motion software and algorithms. We design, build and develop all our embedded and motion software in-house. This allows us to achieve absolute control of our simulation specific control of its mechanical and electrical integration. Our software features specialized motion layers and unique algorithms to achieve what we call Motion Integrity or the most accurate representation of simulated motion. Pitch, roll, heave, environment, and our True Haptic engine and road vibrations are some of the best in the industry. Our software also installs quickly and has automatic over-the-air software and firmware updates. Remote tuning and control of the system is convenient and can be done in real-time with a secondary device without having to stop and exit simulation software.
