MRT360B-3N-0260-NNNN

The MRT360B-3N-0260-NNNN synchronous motor from Bosch Rexroth Indramat’s MRT Synchronous IndraDyn T Motors series integrates robust mechanical design with precise electrical characteristics to deliver high-performance motion control. This motor features a Torque Constant of 17.5 Nm/A and a Voltage Constant at 20 °C of 3.2 V/min-1, providing efficient conversion of current to torque across a wide speed range. The rotor assembly includes a Rotor Mass of 9.8 kg and a Moment of Inertia of Rotor of 0.19000 kg·m², ensuring smooth acceleration and stable holding torque even under dynamic load changes. Built for industrial automation, it supports up to Number of Pole Pairs: 15 for fine resolution of torque pulses, while a Power Wire Cross-section of 4.0 mm² accommodates high current throughput with minimal voltage drop. With an Ambient Temperature in Operation of 0 to 40 °C and an open housing design rated Degree of Protection: IP00, the motor is optimized for integration into protected machine environments.

In dynamic applications, the MRT360B motor demonstrates rapid response thanks to its Thermal Time Constant of 8 min and low electrical damping. The Winding Inductivity of 16.5 mH and Winding Resistance at 20 °C of 3.5 Ω yield predictable current profiles and smooth commutation, enhancing multi-axis synchronization. A Discharge Capacity of 4.5 nF improves EMC performance, reducing voltage spikes during high-speed switching events. The combination of a robust rotor inertia and precise pole-pair count supports constant torque delivery from standstill to maximum rated speed, preventing torque drop-off in high-throughput processes. Temperature thresholds—including a Warning Temperature of 145 °C and Shutdown Temperature of 155 °C—enable built-in thermal protection when paired with appropriate drive electronics.

Designed for long-term reliability, this motor’s open construction allows for effective heat dissipation and straightforward maintenance in clean industrial settings. The Temperature Class: 155 rating ensures insulation integrity under occasional overload conditions, while the absence of an enclosed IP rating demands installation in controlled environments or within protective housings. Integration into servo control systems is facilitated by standardized power wiring and thermal sensors, enabling real-time monitoring of winding temperature and current draw. Its flexible mounting orientations and consistent torque output make it ideal for robotic assembly, material handling, and packaging machinery where precision and uptime are critical. When combined with Bosch Rexroth servo drives, the MRT360B-3N-0260-NNNN motor delivers the operational flexibility and durability required for advanced industrial automation applications.
