Overview & Specifications
The MOZA R21 Ultra is the ultimate expression of direct drive technology. Engineered for professional simulation, it combines a massive 21Nm of sustained torque with a groundbreaking new motor architecture. Housed in a sleek, industrial-grade aluminum chassis, the R21 Ultra delivers force feedback with a level of smoothness and detail that sets a new industry standard.
The secret behind the R21 Ultra's performance is its revolutionary flat-wire servo motor. Unlike traditional round-wire motors, this advanced design (commonly found in high-performance EVs) maximizes copper fill rate and efficiency. The result is a high-torque motor that virtually eliminates cogging and torque ripple, providing an incredibly smooth, organic steering feel even at maximum force.
Power is nothing without control. The R21 Ultra utilizes a 21-bit ultra-high-resolution encoder (2,097,152 pulses per revolution) to translate the motor's raw power into precise, nuanced details. The entire unit is encased in an aviation-grade CNC-machined aluminum alloy body, acting as both a rigid structural mount and an efficient heatsink for the intelligent cooling system.
