The Bosch Rexroth Indramat MSK040B-0600-NN-S1-UP0-NNNN synchronous servo motor from the MSK IndraDyn S Synchronous Motors series delivers precision motion control and robust performance for demanding industrial automation environments. Designed and manufactured by Bosch Rexroth Indramat, this 4-pole servomotor features a thermal time constant of 13 minutes that supports rapid thermal stabilization under heavy duty cycles. Low noise operation is ensured by a sound pressure level of under 75 dB, making it suitable for applications where acoustic constraints are critical. The motor’s compact form factor and high torque density enable seamless integration into robotics, CNC machinery, and precision assembly lines.
The MSK040B’s electrical architecture is defined by a continuous standstill torque of 1.9 Nm and a peak torque capacity of 5.1 Nm, driven by a maximum current of 8 AMP and a standstill current of 2 AMP at 60 K. Its torque constant of 0.92 Nm/A and voltage constant of 58.5 V/rpm at 20 °C deliver predictable dynamic response across speed ranges. The winding exhibits a resistance of 8.4 ohms and an inductivity of 35.4 mH, complemented by a discharge capacitance of 1.5 nF for stable current decay. Weighing just 2.8 kg, the motor offers an optimal power-to-weight ratio, while the shaft with keyway ensures reliable torque transmission without slippage.
Operational resilience is reinforced by an ambient temperature range of 0 to 40 °C and tolerance to relative humidity levels up to 95 %, with a maximum temperature change rate of 0.5 °C/min for dynamic environments. The rotor’s moment of inertia of 0.000010 kg·m² fosters rapid acceleration and deceleration, while the 4-pole pair design guarantees smooth torque delivery and minimal cogging torque. The unit’s insulation class of 155 enhances thermal endurance, and natural convection cooling maintains effective heat dissipation without auxiliary fans. Absence of a holding brake reduces inertia and simplifies maintenance; models with brake options are available for vertical or fail-safe hold requirements.
System integration is facilitated by a rotatable 240° encoder connector and a high-precision Hiperface encoder interface supporting 128 signal periods in singleturn optical technology. The standard design (Motor Size 040, Motor Length B, Winding Code 0600) aligns with industry form-factor conventions, ensuring compatibility with Rexroth IndraDrive servo amplifiers. Natural convection cooling and a standard IP65 rating safeguard performance in harsh factory conditions. Ideal for industrial automation, robotics, and CNC applications, the MSK040B-0600-NN-S1-UP0-NNNN motor combines high torque accuracy, environmental robustness, and seamless control integration for modern motion control systems.
