Product Description:
The R720-012EM is a compact and high-performance servo motor designed for precise control in space-constrained systems. This motor delivers a rated output of 57 watts and a rated torque of 0.177 Nxm. The motor is ideal for small-scale automation systems such as robotic joints, testing equipment, or light-duty actuators while operating at a rated armature voltage of 75 V and a rated current of 1.14 A. It provides steady motion control in dynamic environments with a rated revolving speed of 3000 rpm.
One of the important features of the R720-012EM is its capability to handle short bursts of higher loads. It offers a momentary maximum stall torque of 0.441 Nxm and can tolerate a momentary maximum stall current of 2.8 A, enabling it to respond to sudden changes in load without compromising performance. The torque constant of 0.183 Nxm/A and the induced voltage constant of 19.1 mV/min? show the motor's efficiency in converting electrical power into mechanical torque. Furthermore, its electrical time constant of 0.45 ms ensures a rapid response to control signals, supporting precise real-time adjustments in motion.
Weighing just 0.8 kg, including the encoder, R720-012EM is lightweight, making it ideal for mobile or compact devices. Its mechanical time constant of 7.4 ms supports smooth transitions of speed and position changes. The motor's armature resistance of 11.7 ? contributes to energy efficiency and helps maintain consistent performance. With a rated power rate of 1.6 kW/s, this motor provides quick acceleration for fast-cycle operations. Overall, the R720-012EM is a smart choice for engineers looking for compact, responsive, and efficient servo control in precision-driven applications.
