T730B-609EL8N
by Sanyo Denki
The Sanyo Denki T730B-609EL8N is a high-performance DC servo motor in the T SANMOTION Servo Motors series designed for precision industrial automation. Built by Sanyo Denki, the T730B-609EL8N delivers a rated output of 300 W and features a torque constant of 0.273 N·m/A for consistent torque generation. With a continuous stall torque of 1.43 N·m and the capability for reversible rotation, this motor provides robust dynamic control in both forward and backward directions. Housed in an IP40 enclosure, it protects against ingress of solid objects larger than 1 mm, making it well suited to controlled factory environments.
The motor’s electrical specifications are engineered for demanding applications: it operates at a rated armature voltage of 75 V with a rated armature current of 5.2 A, achieving a rated rotating speed of 2500 rpm. Under peak conditions, it can handle an instantaneous maximum armature current of 40 A and produce an instantaneous maximum torque of 9.8 N·m. The stall armature current is 5.5 A, while the friction torque is 0.05 N·m and the viscous braking constant is 0.039×10⁻³ N·m/min. Designed for responsive acceleration, it offers an instantaneous maximum angular acceleration of 38.4×10³ rad/s².
Operational features of the T730B-609EL8N emphasize reliability and control. The motor achieves a maximum rotating speed of 4000 rpm under light load conditions, while its rated power rate of 5.1 kW/S supports rapid load changes. A built-in DC 48 V brake ensures secure stops, enhancing safety during emergency conditions. Thermal stability is maintained across an ambient temperature range of 0°C to 40°C, and humidity tolerance spans 20% to 90% RH (non-condensing). Dual-direction rotation control and low friction torque contribute to smooth motion profiles in precision robotics and indexing systems.
This servo motor integrates seamlessly with industrial drive controllers and motion processors to form advanced automation solutions. By leveraging the T730B-609EL8N in coordinated multi-axis setups, system designers can achieve tight synchronization and high throughput. Ideal target applications include conveyor indexing, pick-and-place robotics, CNC machine auxiliary axes, and factory assembly lines. The combination of high torque density, rapid response, and rugged IP40 protection makes this module a reliable choice for modern industrial control systems.
