Product Description:

The T730T-012EL8N is a brushless servo motor developed by Sanyo Denki within the T SANMOTION Servo Motors series. It serves as a compact drive element that converts electrical energy from a matching amplifier into controlled rotary motion for indexing tables, packaging axes, and other automated equipment. By combining a permanent-magnet rotor with precision feedback devices, the unit delivers programmable position, velocity, and torque responses that allow machine controllers to synchronize multiple axes without mechanical gear changes.

At its continuous operating point, the motor supplies 300 W of mechanical power while running at a rated speed of 2500 rpm. That output corresponds to a rated shaft torque of 1.18 N·m, produced when the windings draw a rated armature current of 5.2 A from a drive that applies 75 V DC. The electrical response is influenced by an armature inductance of 1.6 mH and an armature resistance of 1.1 Ω, which affect current rise time and copper losses. A torque constant of 0.273 N·m/A links commanded current to developed torque, while a voltage constant of 28.6 × 10⁻³ V per rpm sets the back electromotive force at speed. The 76 mm outer diameter permits direct flange mounting in compact machinery without additional adapters.

The servo can deliver an instantaneous maximum torque of 9.8 N·m for rapid acceleration. It also provides a continuous stall torque of 1.43 N·m when the shaft is locked. A rotor inertia of 0.270 × 10⁻³ kg·m² offers a balance between fast response and speed stability. Position feedback comes from a 1,000-pulse-per-revolution incremental encoder, while a tachogenerator with 1% linearity supplies an analog speed signal for legacy drive cards. These feedback devices allow the connected drive to monitor shaft movement and correct deviations during changing load conditions. The available torque and feedback signals support tightly regulated motion during repetitive pick-and-place, indexing, and winding processes.
