Introducing the MOZA R21 and R25 Ultra Wheelbases
Introduction
MOZA has just introduced two exciting new wheelbases: the R21 and R25 Ultra. These models were revealed at Gamescom in August, and they’re expected to start shipping later this month. One of the key upgrades in both the R21 and R25 is the new zero-cogging flat-wire motor. This innovation promises to deliver higher torque density, better thermal performance, and most importantly, eliminates the issue cogging torque The result is a more durable and reliable motor, built to handle specific sim racing demands.
In this post, we’ll take a closer look at what makes these new wheelbases stand out. I’ll break down their standout features, dive deeper into the zero-cogging flat-wire motor, and explore how these innovations are set to elevate experiences for all sim racing styles.
The MOZA Racing R21 Ultra Wheelbase
The R21 Ultra Wheelbase promises to deliver an immersive experience for sim racers. MOZA considers it in the "upper mid-range" of direct drive wheelbases, making it suitable for both novice and experienced sim racers alike. Furthermore, it introduces noticeable upgrades including a higher torque, a zero-cogging flat-wire motor, intelligent cooling, and more advanced force feedback. I will talk more about the zero-cogging flat-wire motor for more clarity and reasons why it may be a game-changer.
According to MOZA Racing, the zero-cogging flat-wire motor serves a multitude of purposes, including minimizing cogging torque and improving force feedback. This means that the motor will deliver smoother, more consistent steering responses, even at lower speeds. Cogging, which is often experienced with traditional motors in lower-end wheelbases, occurs when the motor's rotation becomes uneven due to the interaction of magnetic poles. This can result in a jerky, less responsive feel when making subtle adjustments to the wheel. With the zero-cogging flat-wire motor, MOZA addresses this issue by using a flat-wire design, which allows for a more efficient and precise distribution of power.
The MOZA Racing R25 Ultra Wheelbase
The R25 Ultra Wheelbase features 25 Nm of torque for powerful and responsive movements. According to MOZA, this wheelbase achieves "0.1% sampling accuracy and a 2 kHz response rate," for precise handling and output, making it one of the strongest wheelbases on the market. The R25 also features the same zero-cogging flat-wire motor for 26% higher torque density and smooth rotation. With this, MOZA also encourages use of the R25 Ultra with iRacing 360Hz Mode for the most immersive and cutting-edge sim racing experience.
Moreover, MOZA's latest force feedback algorithm further enhances the realism of the R25 Ultra's performance. The algorithm dynamically adjusts the strength and response of the force feedback in real-time, ensuring that each input feels highly accurate and true-to-life. This system works perfectly with the wheelbase’s high sampling rate and torque output and offers a responsive driving experience that provides the driver with more control. This base is recommended for committed sim racers and semi-professional race car drivers.
Conclusion
MOZA's Ultra Wheelbases mark a significant leap forward in sim racing. By introducing the new zero-cogging flat-wire motor, MOZA has successfully tackled one of the longstanding issues in force feedback performance: cogging torque. This innovation ensures a smoother, more precise, and immersive driving experience across all skill levels.
The R21 Ultra is an excellent choice for sim racers looking for a high-quality, versatile wheelbase that combines performance and affordability. On the other hand, the R25 Ultra Wheelbase is designed for enthusiasts and semi-professional drivers who want to experience the most realistic virtual racing performance.
