Product Description:
Under nominal operating conditions, the module T720T-012 of T SANMOTION Servo Motors product series from Sanyo Denki delivers rapid dynamic performance. With a mechanical time constant of 4.3 ms, the drive certainly gives swift acceleration and deceleration. The motor’s low viscous braking constant of 0.020 × 10⁻³ N·m/min⁻¹ minimizes resistance during quick stops, while a rotor inertia of 0.147 × 10⁻³ kg·m² contributes to the motor’s agile response.
The instantaneous maximum torque of 5.4 N·m accommodates sudden load changes and the torque constant of 0.21 N·m/A reliably translates current into torque. A voltage constant of 21.8 × 10⁻³ V/min⁻¹ further ensures that output voltage scales predictably with speed. Electrically, the armature winding resistance of 5.1 Ω reduces heat generation during continuous operation and increases reliability. Rated at 200 W, the component provides steady power for medium‑duty industrial and automation tasks. Thermal management is optimized by a resistance of 2.4 K/W for efficient heat dissipation with a thermal time constant of 30 min that indicates sustained performance before reaching thermal equilibrium under load.
Precision motion control of T720T-012 servo module is supported by an optical encoder offering selectable resolutions of 200, 500, and 1000 P/R for fine position feedback. An IP43 protection rating safeguards against solid objects and spraying water, enhancing reliability in various environments. The unit operates at a rated speed of 3000 min⁻¹ with a maximum of 5000 min⁻¹ for high‑speed requirements. When unpowered, a holding brake torque of 1.47 N·m and a holding brake mass of 0.59 kg secure the motor’s position without unduly increasing its weight.
