The MSK076C-0300-NN-M1-UG1-NNNN from Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series, combining robust construction with high-precision performance. This standard IndraDyn S Synchronous Servomotor features a motor size of 076 and a motor length designation of C, delivering a compact yet powerful solution for demanding automation tasks. With a plain shaft design, it accommodates a Holding Brake, electrically-released that provides a holding brake torque of 11 Nm. Rated for an ambient operating temperature range of 0°C to 40°C and an installation height up to 1000 meters, this motor ensures reliable operation in diverse industrial environments.
Built around a surface cooling scheme with natural convection, the MSK076C-0300-NN-M1-UG1-NNNN achieves continuous torque at standstill of 13.5 Nm at 100 K overtemperature and 12.0 Nm at 60 K. It draws a continuous current at standstill of 8.1 A (100 K) and 7.2 A (60 K), while peak current capability reaches 32.4 A to support brief overload conditions. The motor exhibits a maximum torque rating of 43.5 Nm and delivers a torque constant of 1.84 Nm/A at a reference temperature of 20°C. Its winding resistance is 1.85 Ohm, and the winding inductivity stands at 12.6 mH, optimized for rapid current response and precise torque control.
Operational features include an optical encoder interface using Hiperface technology, offering 128 signal periods per revolution and Multiturn Absolute position feedback via a rotatable encoder connector (240°). The rotor inertia of 0.0043 kg·m² ensures dynamic response, while the leakage capacitance of 6.5 nF minimizes electrical noise. The unit maintains a thermal time constant of 25 minutes, facilitating predictable heating behavior under load. With a maximum speed of 4700 min⁻¹ and sound pressure level below 75 dB(A), the motor balances performance with low acoustic emissions. It delivers IP65 protection, safeguarding against dust and water ingress, and leverages high-quality materials for long-term durability.
Integration is straightforward thanks to the standardized Winding Code 0300 and compatibility with Bosch Rexroth IndraDrive controllers. The compact housing and plain shaft design support direct coupling to gearboxes or load devices without additional adapters. Ideal for machine tools, packaging lines, robotics, and rotary indexing systems, the MSK076C-0300-NN-M1-UG1-NNNN excels in applications requiring precise position control, rapid acceleration, and secure holding under power-off conditions. Its combination of advanced encoder feedback, robust braking, and thermal management makes it a versatile choice for modern automation projects.
