Product Description:
The T511T-012EL8N is a DC servo motor manufactured by Sanyo Denki for the T SANMOTION Servo Motors series. It acts as a prime mover in automated pick-and-place heads, indexing tables, and compact gantries, converting regulated armature current into precise shaft rotation for closed-loop positioning tasks in industrial automation. A built-in tachogenerator and incremental encoder supply real-time speed and position data to the drive controller, enabling tight following-error control during rapid cycles. The motor’s small frame and moderate heat dissipation simplify installation in dense machine layouts.
Under continuous duty, the motor outputs 110 W of mechanical power while turning at a nominal speed of 3000 rpm. At that operating point, it generates 0.34 N·m of torque from a supply of 80 V with an armature current of 2.0 A. The electromagnetic circuit has an armature inductance of 3.2 mH, which affects current rise time and the response bandwidth available to the drive controller. With a drive that can sustain these electrical limits, the motor remains within its thermal operating range without external cooling hardware, making it suitable for continuous automation lines that run multiple shifts.
During acceleration, the shaft can reach 5000 rpm, and transient load surges are handled by up to 3.4 N·m of instantaneous torque before the motor approaches its magnetic limits. A rotor inertia of 0.037 × 10⁻³ kg·m² supports rapid speed changes, while the mechanical time constant of approximately 4.3 ms allows the axis to settle quickly after each move. The continuous stall torque is 0.42 N·m, providing holding and low-speed torque within the motor’s thermal limits. A torque constant of 0.21 N·m per ampere relates armature current to developed torque, while an armature resistance of 5.1 Ω affects voltage drop and copper loss. Motion controllers use these values when shaping acceleration, deceleration, and load-response profiles.
