Product Description:

The T730-112E59 is a permanent-magnet AC servo motor manufactured by Sanyo Denki within the T SANMOTION Servo Motors series. Intended for precision motion systems, it delivers controlled rotary power so CNC tables, packaging lines, and semiconductor handlers can follow programmed trajectories with accurate feedback. The motor connects to a matched digital amplifier, where current commands translate directly into electromagnetic torque. This arrangement supports precise interpolation and multi-axis synchronization in demanding industrial environments.

The motor has a continuous rated output of 300 W. When supplied with 75 V DC from the amplifier, the stator draws 5.2 A to develop a shaft torque of 1.18 N·m while maintaining a speed of 2500 rpm. The copper windings have an armature resistance of 1.1 Ω. Electromagnetic coupling provides a torque constant of 0.273 N·m/A and a back-EMF constant of 28.6 × 10^-3 V/rpm. These electrical values help users configure the amplifier’s current loop and estimate heat generation during continuous operation.

For short acceleration periods, the motor delivers a peak torque of 9.8 N·m. Its 4.0 ms mechanical time constant supports rapid response to changes in commanded motion. The rotor inertia is 0.270 × 10^-3 kg·m², which supports quick acceleration and settling in high-throughput machinery. Current transients are shaped by an armature inductance of 1.6 mH, allowing responsive current regulation while helping filter switching harmonics. Position feedback is produced by a line-driver encoder with an incremental resolution of 2500 P/R, and its differential signals are compatible with suitable servo drives. The frame has an outer diameter of 76 mm, allowing installation in compact machine assemblies.
