• speed reducer
• Precise control: fixed step angle; no accumulation of angular error; high positioning accuracy
• Self-locking position: rotor automatically locks after power failure; no additional braking device is required
• Low-speed stability: stable torque in low-speed operation; no deceleration mechanism required
• Rapid response: fast start-stop reversal response; suitable for fast positioning scenarios
• Simple structure: open-loop control without sensors; simple structure
