Bsimracing Sim Racing Resources and News for the racing enthousiast.
During the GDC Festival of Gaming event held from March 9-13, 2026, at the Moscone Center, San Francisco, CA, the Chinese MOZA Racing brand introduced its HMA150 Motion Actuator system to the public.
With this in-house developed high-performance linear motion actuator, Moza Racing set out to bridge the gap between consumer-grade sim racing and professional-grade motion simulation. The actuators are the most important part of the Moza Motion Platform Ecosystem, letting you build your own 4-axis 3DOF motion system with heave, pitch, and roll.
As the name implies, the Moza HMA 150 is an actuator with a 150 mm travel distance, which is more than the more common entry-level 100 mm, allowing for a more dramatic and detailed motion. The actuators can operate at a Maximum Velocity of 300 mm/s, and a 0–150 Hz haptic feedback.
The Moza HMA 150 makes use of a proprietary high-torque servo motor with a ball-screw drive, which is more efficient and durable than lead screws, allowing for the HMA150’s high 150 kg weight capacity.
The motor controller and power management systems are integrated into the actuator housing. Integrating motor controllers and power management systems directly into the actuator housing offers significant advantages in motion control systems, including increased efficiency, enhanced reliability, and simplified installation.
Combining these components results in a compact system eliminating the need for bulky, separate control boxes and reduces the complex cable harness to simple power and data connections.
The movement is measured by high-resolution encoders able to read 2.09 million points (approx. 21-bit). This ensures that the controller unit always receives an accurate position of the actuator. The HMA150 actuators are controlled via a high-performance 600 MHz dedicated Microcontroller, translating the game telemetry into almost real-time physical movement at a sub-millisecond latency.
On the software side, the actuators are controlled via the new standalone MOZA Motion Manager software, which features Adaptive AI Algorithms that can predict upcoming motion, based on track data to smooth out transitions.
Each HMA150 actuator connects to a MOZA Motion Controller/Hub using a high-speed industrial CAN bus (Controller Area Network) or a proprietary shielded RJ45-style data cable. The Hub then connects to your PC via a single USB-B or USB-C cable. Also important, the system is built on a 48V low-voltage architecture, emphasizing home safety while maintaining the high torque required for rapid motion.
At the time of writing, Moza Racing has not yet released an official MSRP for the HMA150 Motion Actuator. Pre-orders are rumored to open in Q2 2026 (April–June).
Key Technologies
What sets the HMA150 apart from basic DIY actuators is the integration of Moza’s motor control expertise:
- Ultra-Low Latency: Leveraging Moza’s existing work in Direct Drive (DD) wheelbases, the HMA150 boasts millisecond-level response times. This is crucial for “feeling” the bite point of tires or the vibration of rumble strips before your eyes see it.
- Silent Operation: Despite the high force output, the internal ball-screw mechanism and helical gear design are optimized to minimize mechanical noise, making it more suitable for home environments.
- Integrated Servo System: Unlike some actuators that require massive external control boxes, the HMA150 features a highly integrated design that simplifies cable management.
Software & Ecosystem
The HMA150 is managed via the MOZA Pit House software. This provides a unified interface where you can:
- Adjust Intensity: Fine-tune how much “wash” (vibration) or “surge” (acceleration/braking feel) you want.
- Game Support: It features native plug-and-play support for major titles like iRacing, Assetto Corsa, and F1 24.
- Safety Features: Includes software-level travel limits and emergency stop integration to prevent the rig from over-extending or causing injury during a crash.
