With several different three axis (3dof) motion base platform models choose from and starting at 500 pounds (227 Kgs) and going up to 4000 pounds (1818 Kgs), Servos & Simulation has a wide selection of systems for all types of application. All of our standard three axis (3dof) motion base platform systems are completely customizable for the customer's application. All systems come with an integrated top platform that can be modified and customized per customer requirement. Adding seats, cockpits, cabins, or equipment? Let us know and we can make the top pre-drilled for your item or make the cockpit, cabin, and seats!
Designed typically for military, commercial, and entertainment applications, the three axis (3dof) motion platform systems are fully electric, digitally controlled, and are virtually maintenance-free. Highly efficient and with the lowest cost of ownership in the industry, these systems will provide decades of worry-free service. Clean and environmentally green, these systems are highly reliable, safe, and have a proven design. With a totally sealed design, these systems can be operated in the most abusive and harshest conditions.
The 500 lbs and under three axis bases are single/dual rider systems meant for gaming rides, car simulators, seat shakers, virtual reality entertainment or other small testing applications. The 1,000 lbs three axis bases are designed for rides accommodating 1-4 people near the center of the base. The 2,000 lb. or larger payload three axis bases are designed to accommodate the top with several seats, including the walkway (typically a 4’ x 6’ top – other are available as are custom tops). Your imagination is the limit!
Other combinations of strokes and payloads can be accommodated at an additional cost based on the contract.
Three Axis (3DOF) Motion Base Platform - Basics
A three axis motion base platform has the following axes: roll, pitch, and heave.
All motion base platforms are servo-controlled... this means that there is a closed feedback loop between the motor and the motor controller (drive amplifier). When the system receives a signal from either the computer or an analog control voltage, the motor moves in relation to the input signal (typically ±7.5v). If it receives a negative voltage, the crank on the motor moves down; a positive voltage, the crank moves up. There are no encoders, no limits, or stop for the upper and lower positions as there are in linear systems as none are required.
What is Included?
All motion base platform systems come with integrated electronics installed in COTS rack mount chassis which makes for ease of installation. Up to 50' of cables are included to interface the electronics to the motion base. Hubbell standard 220VAC plug, mating input connector, and generic system manual are included. Integrated safety braking system and e-stop integration are standard for every system. Standard system manual (ICD and maintenance) and a full drawing set are included. All systems come with a full one year warranty and lifetime email/phone technical support. For more information on our warranty, please click here. Extended warranties are available.

Motion Base Platform Systems – Optional Control Systems
With any option, the system is plug and play ready!
Computer Control– If the customer does purchase the computer system for control of the motion base, included is the computer with the control board, the input cable, operating system, keyboard, mouse, and maintenance software for the motion base. If the customer is purchasing the computer for entertainment ride profile playback and control, the computer can broadcast the video while running the motion base. Customer can specify video card output at contract time. The 8000 pound or larger systems come with the computer standard.
Raspberry Pi and Phidgets– Since the motion base platform systems are controlled with an analog signal, they can be controlled with either a Raspberry Pi with a DAC installed or with a Phidget card such as the 1002_0B or OUT1002_0. With this option, enthusiasts with home brewed flight simulators can interface the motion base platform systems to Prepar3d, Flight Simulator Steam or X-Plane.
Measurement Computing– all of Measurement Computing ±10VDC analog output devices will work with any of the motion base platform systems. Please check with our engineering department to get the fast one available so that the motion base platform performance is not hindered.
The customer is more than welcome to choose their own interface. We are here to help with engineering and advice where and when you need it.
Standard power requirements are 220VAC with other optional voltages available. The motion platforms are completely electric and environmentally green. The smaller bases can be configured to run from a standard 120 volt, 20 amp circuit with the use of a transformer (customer may purchase the transformer or we can provide at an additional cost). The mid-size bases (1,000 to 4,000 lbs) require 220 volt, either single phase or three phase and the largest bases (6,000 lbs and up) requiring from 220 to 440 volts AC, three phase. We can wire the system per customer specific electrical requirements.
