Hongyuan – Direct Torque Control Type


This all-in-one drive adopts the industry-first direct torque control technology without a speed sensor, delivering high-end performance that closely rivals European benchmark products. In particular, it represents significant technological breakthroughs and early-stage product implementations in key areas such as torque control accuracy, torque response speed, and torque energy efficiency ratio. Its defining characteristics include: replacing closed-loop vector control (when not using position control); providing efficient and reliable drive for all AC motors, enabling direct drive when paired with low-speed PM motors; and supporting mainstream communication protocols.
