Product Description:
The T511T-012 is an AC servo motor built by Sanyo Denki for the T SANMOTION Servo Motors series. Engineered for closed-loop drive systems, the unit supplies precise rotational motion to pick-and-place robots, indexing tables, and packaging axes where repeatable speed and torque are required. By responding quickly to command signals from a servo amplifier, it helps machine designers achieve accurate positioning and consistent throughput in industrial automation processes.
At its nominal operating point, the motor produces 110 W of mechanical power while turning at 3000 rpm and delivering 0.34 N·m of torque. This operating point is supported by a rated armature current of 2.0 A. The motor has an armature inductance of 3.2 mH and a resistance of 5.1 Ω, which influence current ripple and thermal rise in the drive circuit. A torque constant of 0.21 N·m/A links commanded current to developed torque, allowing the controller to calculate setpoints directly. Continuous stall torque is 0.42 N·m, providing static holding force without overheating. The mechanical time constant is 4.3 ms, indicating how quickly the rotor responds to a step change in voltage.
For transient events, the winding can accept a peak current of 18 A, producing up to 3.4 N·m of torque for short periods during rapid indexing or shock-load absorption. The motor operates on a 75 V system supplied by the matching SANMOTION amplifier. A low rotor inertia of 0.037 × 10⁻³ kg·m² permits high acceleration while minimizing overshoot. The motor has a 51 mm outer diameter and a 144.5 mm overall length, allowing installation in narrow mechanical enclosures. The built-in tacho generator supplies 7 V per 1000 rpm to the drive, providing real-time speed feedback without an external encoder. Its electrical and thermal characteristics support stable operation during continuous duty.
