T730BG7-012EL0
by Sanyo Denki
The Sanyo Denki T730BG7-012EL0 is a precision servo motor from the T SANMOTION Servo Motors series by Sanyo Denki, designed to deliver reliable performance in demanding industrial automation applications. This unit operates at a rated voltage of 75 V and produces a rated power of 300 W, providing a compact yet powerful solution for robotics, CNC machines, and conveyor systems. With a mass of 2.5 kg, the motor strikes an optimal balance between structural stiffness and nimble responsiveness. Its incremental encoder type EL0 integrates seamlessly for closed-loop control, ensuring high positional accuracy and dynamic response. The combination of a compact flange dimension of 76 mm and robust construction makes the T730BG7-012EL0 an ideal choice for space-constrained installations.
Technical specifications of the T730BG7-012EL0 demonstrate its exceptional capability across a wide range of operating conditions. The motor delivers a rated torque of 1.18 N·m and sustains a continuous stall torque of 1.43 N·m, while its maximum speed of 4000 min⁻¹ ensures rapid motion when required. Electrical characteristics include a rated current of 5.2 A, a torque constant of 0.273 N·m/A, and a voltage constant of 28.6 × 10⁻³ V·min⁻¹, enabling precise current-to-torque conversion. Thermal management benefits from a thermal resistance of 1.2 K/W and a thermal time constant of 30 min, limiting temperature rise to 105 K under sustained load. For feedback versatility, the motor supports an encoder resolution (line driver) of 1000/2000/5000 P/R and encoder resolution (open collector) of 200/500/1000 P/R, catering to diverse control architectures.
Operational features of the T730BG7-012EL0 emphasize reliability and ease of use in industrial environments. The high-resolution encoder ensures smooth acceleration and deceleration profiles, minimizing overshoot and vibration during high-speed motion. Robust lubrication-free bearings reduce maintenance requirements, while the motor’s insulation and construction withstand typical factory ambient temperatures from 0 °C to 40 °C. The integrated feedback and drive characteristics support rapid startup and high dynamic response, allowing for precise trajectory control in pick-and-place and indexing applications. The motor’s compact design facilitates straightforward mounting, and its mass of 2.5 kg contributes to a reduced moving inertia in multi-axis systems.
Integration of the T730BG7-012EL0 into existing machine frameworks is seamless thanks to its standardized flange and shaft interface. The unit interfaces directly with Sanyo Denki’s range of servo drives, leveraging built-in electronic parameters for quick commissioning and diagnostics. Its combination of rated speed of 2500 min⁻¹ and maximum speed of 4000 min⁻¹ makes it suitable for both low-speed torque-intensive tasks and high-speed precision operations. From automated assembly lines to robotic articulation and high-precision positioning systems, the Sanyo Denki T730BG7-012EL0 offers engineers a versatile, high-performance servo solution.
