Product Description:
The T730B-569EL8N is a permanent-magnet servo motor manufactured by Sanyo Denki within the T SANMOTION Servo Motors series. Designed for closed-loop motion systems, it converts DC bus energy from a drive into precisely controlled shaft rotation for positioning tooling, conveyors, and semiconductor stages. The motor integrates an electromagnetic brake and an incremental encoder, giving machine builders a compact axis solution that handles power delivery, feedback, and load holding in one assembly suitable for multi-axis robots and general industrial automation.
At its nominal operating point, the rotor turns at 2500 rpm, delivering 300 W of mechanical power while drawing 5.2 A from a 75 V armature supply. Continuous torque available at standstill is 1.05 N·m, and copper losses are limited by the 1.1 Ω phase resistance. The winding generates 0.273 N·m of torque for every ampere commanded. The laminated steel core and compact 76 mm frame provide thermal mass that helps the motor remain within its temperature limits during sustained loads. A mechanical time constant of 4.0 ms indicates the speed response to load transients, enabling the drive controller to tune velocity loops for quick and steady acceleration profiles.
The motor has a 2.45 N·m peak torque rating that supports rapid positioning movements. Position feedback is supplied by a 1000 P/R incremental encoder, giving the control system fine resolution for interpolation and electronic gearing. The electrical time constant of 1.5 ms means the phase current reaches 63% of its final value shortly after a voltage step, supporting high-bandwidth torque control. With a rotor inertia of 2.708 × 10⁻⁴ kg·m², the motor balances quick reversal capability against load stability. An electromagnetic brake handles stopping and holding loads on vertical axes by clamping the shaft with 1.47 N·m of torque while operating from a 90 V supply and drawing 0.11 A.
