T730-042E59
by Sanyo Denki
The Sanyo Denki T730-042E59 is a precision servo motor from the T SANMOTION Servo Motors series by Sanyo Denki. It delivers a rated output of 300 W at a rated armature voltage of 75 V and produces a rated torque of 1.00 N·m. With a rated rotating speed of 2500 min⁻¹, this motor is designed for high‐performance motion control in demanding industrial environments. Its primary function is to offer responsive, closed‐loop position and speed regulation when paired with compatible Sanmotion T amplifiers.
This servo motor features a continuous stall torque of 1.05 N·m and an instantaneous maximum torque of 2.45 N·m, enabling robust start‐up and acceleration. The torque constant is 0.273 N·m/A, and the voltage constant is 28.6 × 10⁻³ V/(min⁻¹), ensuring efficient energy conversion. Electrical and mechanical dynamics are managed with an electrical time constant of 1.5 ms and a mechanical time constant of 4.0 ms, supporting rapid response in feedback loops. The motor sustains a rated armature current of 5.2 A (stall current 5.5 A) and tolerates an instantaneous maximum armature current of 10.9 A.
Built for reliability, the T730-042E59 employs an Encoder Specification EA59 variant with 1000 pulses/rev (line driver output) to provide high‐resolution positional feedback. Weighing 2.75 kg including the sensor, it maintains a compact footprint. Although it lacks an integrated brake or tacho generator, it remains compatible with all Sanmotion T-series amplifiers via the CN2 port, assuring seamless integration in automated systems. This motor’s dust- and moisture-resistant chassis, fast time constants, and precise encoder feedback make it an ideal choice for industrial robotics, CNC machinery, and other applications where accuracy, durability, and efficiency are critical.
