3DOF Motion Platform

Designed, built and tested by CSCMotion

Custom 3DOF Motion Platform

We design and manufacture servo-electric three-axis platforms for industrial testing, research and OEM equipment. Our reference series controls heave, roll and pitch; when your application needs another axis combination, we evaluate a custom mechanism around the load and motion task.

Our reference range covers 100 to 30,000 kg payload classes, with custom configurations available. We confirm the final load rating and motion envelope from your complete moving assembly, center of gravity, inertia, trajectory and duty cycle.

Define the three axes before selecting a model

Start by Defining the Three Required Axes

“3DOF” means three controlled degrees of freedom, but it does not identify one universal axis set. Tell us which translations and rotations your application needs; we record the axes, signs, units and coordinate frame in the project specification.

Our reference product classes use heave, roll and pitch. If you need yaw, surge, sway or another combination, we evaluate it as a custom architecture instead of applying performance from the reference series.

Our reference configuration uses Z-axis heave, roll about X and pitch about Y. We confirm coordinate signs, rotation center and command units with your team in the interface document.

We do not apply one set of heave, roll, pitch, speed, acceleration or power figures to every project. We calculate these values for the approved geometry and operating condition, then record them in the project datasheet.
Requirement-driven engineering

We Engineer the Platform Around Your Motion Task

Before we select actuators or platform geometry, we define the three axes and complete moving system. These inputs allow us to size the platform correctly and set measurable acceptance criteria.

01 Selected axes

Confirm heave, roll and pitch or identify the alternative three-axis combination required.

02 Moving mass

Include the payload, fixture, top frame, cabin, operator and every item that moves.

03 Center of gravity & inertia

Provide the CG location and inertia where available; both directly affect actuator load and usable motion.

04 Travel, angle & pivot point

Define heave, roll, pitch, rotation center and the simultaneous trajectories that matter.

05 Dynamics & duty cycle

Velocity, acceleration, frequency content, motion profile and operating hours.

06 Integration & acceptance

Share the top-frame, footprint, power and host-interface constraints, and confirm safety and FAT responsibilities.

Specifications you can review and approve

What We Confirm in Your Project Datasheet

We issue configuration-specific data rather than a generic list of maximum values. Each figure in the project datasheet is tied to the selected axes, approved moving assembly, geometry and operating condition.

Specification Customer input Engineering output Why it matters
Axis definition Required translations and rotations Named axes, signs, units and coordinate frame Prevents different meanings of “3DOF”
Moving load Payload, fixture, top frame and accessories Rated payload and gross moving load definition Prevents undersizing around the test article alone
CG & inertia CG coordinates and mass distribution Approved CG and inertia condition Changes force, torque and available motion
Heave / travel Required vertical or project-specific translation Single-axis and combined-axis usable travel Actuator stroke is not equal to platform travel
Roll & pitch Required angles and rotation center Angular range around an agreed coordinate frame Pivot point changes actuator motion and load
Dynamics Velocity, acceleration, frequency and trajectory Achievable values under approved conditions Peak and continuous operation are different
Structure Top frame, footprint, height and mounting Outline drawing and installation interfaces Geometry determines motion and site fit
Electrical & control Power, environment, duty cycle, host commands and I/O Cabinet, protection and interface definition Avoids late installation and software risk
Safety & FAT Risk boundaries and acceptance objectives Limits, interlocks, test plan and deliverables Makes acceptance measurable before shipment
We confirm performance after reviewing the selected axes, moving load, CG, inertia, platform geometry, simultaneous motion and duty cycle.

Payload, CG and combined motion

Why Mass Alone Is Not Enough

A compact centered fixture and a tall offset assembly may weigh the same, but they do not place the same demand on the actuators, joints or structure during roll and pitch. We select the platform from the complete moving assembly—not the payload figure alone.

Single-axis limits are not the same as simultaneous heave, roll and pitch capability. We calculate the usable combined workspace around your approved load, rotation center and operating trajectory.

Electric actuation / closed-loop feedback

How Our 3DOF Platform Produces Coordinated Motion

Our controller coordinates the platform mechanism to generate the commanded heave, roll and pitch pose. Servo drives and feedback devices close the motion loop while software limits keep the platform inside the approved workspace.

Different three-axis mechanisms create different load paths, footprints and service requirements. We confirm the actuator arrangement and performance against the selected model or custom design.

Architecture selection

3DOF vs 6DOF Motion Platform

More axes do not automatically create a better system. We recommend 3DOF when three named axes cover the task, and 6DOF when the assembly needs full translational and rotational pose control.

Full pose motion

6DOF Motion Platform

Best when surge, sway, heave, roll, pitch and yaw are all needed for the approved trajectory or test method.

Review 6DOF platforms →
Focused motion

3DOF Motion Platform

Best when heave, roll and pitch—or another explicitly defined three-axis set—covers the required task.

Define the required three axes →
Axis count alone does not determine price or performance. We compare the usable workspace, moving assembly, dynamics, integration scope and acceptance method for your actual project.
Reference geometry or project engineering

Reference Configuration or Custom Three-Axis Geometry?

A reference configuration is the fastest route when your load and heave, roll and pitch requirements fit an existing platform family. We develop a custom mechanism when the axes, moving assembly or installation require another geometry.

Reference starting point

Configure an Existing Platform Family

We start from a 100–1000 kg reference class, then confirm the moving frame, workspace, controls and project options.

3DOF motion platform price

What We Need to Prepare an Accurate Quote

Price depends on the selected axes, complete moving load, travel, angles, dynamics, structure, controls and delivery scope. Two projects in the same payload class can require different platforms because their CG, motion and duty cycle are different.

We prepare the quotation from your approved requirements and clearly separate included equipment, optional items and customer-supplied scope.

Answers from our engineering team

3DOF Motion Platform FAQ

A 3DOF motion platform controls three defined degrees of freedom. Our reference series uses heave, roll and pitch for vertical translation and two-axis tilt.

The term does not identify one universal axis set. Tell us which translations and rotations you need; we confirm the selected axes, signs, units and coordinate frame in the project documents.

Yes. Our 100–500 kg reference classes use heave, roll and pitch. If your application needs another three-axis combination, we review it as a custom architecture.

Yes, but yaw is not part of our heave, roll and pitch reference series. We review the mechanism, range, load, footprint and controls separately for any design that includes yaw.

We offer 100, 150, 300 and 500 kg reference classes. We confirm the final configuration from the gross moving mass, center of gravity, inertia, workspace and duty cycle.

A 3DOF platform controls three selected axes. Our 6DOF motion platform controls surge, sway, heave, roll, pitch and yaw. We recommend the architecture that matches your motion task, usable workspace and acceptance objective.

We select the interface around your host system. Our project experience includes USB, CAN, RS232, RS485, Ethernet and fieldbus-based architectures. We confirm commands, units, timing, I/O, status, limits and responsibilities in the interface document.

Yes, when customer confidentiality and media permissions allow. We publish approved assembly, factory-test, finished-system and installation media, and we limit project names and specifications to cleared information. See our 3DOF project media section.
