MSK050С-0450-NN-M1-U-G0-NNNN
The MSK050С-0450-NN-M1-U-G0-NNNN from Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series, designed for precision torque control in industrial automation. This synchronous servomotor offers a maximum torque of 18.8 Nm and a torque constant of 1.16 Nm/A, enabling accurate force output proportional to current input. With a protection class (en 60034-5) rating of IP65, it is well suited for harsh manufacturing environments that demand dust and water resistance.
In technical terms, the MSK050С-0450-NN-M1-U-G0-NNNN features a maximum current rating of 18.8 A, a voltage constant of 71.5 V/1000 min⁻¹, and a winding inductance of 20.2 mH. The device contains 4 pole pairs and a winding resistance of 3.2 Ω, contributing to precise synchronous rotation and stable performance under varying loads. Its sound pressure level remains under 75 dB(A) for quieter operation, while a leakage capacitance of 2.4 nF minimizes electrical noise, ensuring compatibility with sensitive drive electronics.
Additional features include an operable ambient temperature range of 0–40 °C and a thermal class (en 60034-1) rating of 155, protecting internal windings from thermal degradation. The motor’s thermal time constant of 14.0 min allows predictable heating and cooling cycles in heavy-duty applications. A moment of inertia of rotor at 0.00033 kg·m² offers rapid acceleration and deceleration, while the flange design conforms to DIN 42948 standards for easy integration. These attributes combine to deliver a durable, efficient servomotor that enhances productivity and reliability in demanding industrial settings.
