Product Description:
The MSK075E-0300-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers precise closed-loop rotary motion to packaging lines, pick-and-place modules, and forming presses. This variant is supplied in motor length E, giving it mid-range torque capability while keeping the overall envelope compact enough for tightly spaced multi-axis assemblies. Because it is a synchronous servomotor, it can respond quickly to drive commands and maintain stable motion through repeated acceleration and deceleration cycles. It can be used where precise starts, stops, and short positioning moves are required without excessive motor size.
The motor is cooled by natural convection, so the installation must allow free ambient airflow rather than forced ventilation. A 240° rotatable encoder connector lets the feedback cable be positioned after mounting to ease cable routing in compact machine layouts. The connector can be turned to reduce cable strain and to avoid sharp bends close to the housing. Position data are transferred via the Hiperface serial protocol, and the optical encoder provides 128 signal periods per mechanical revolution for fine interpolation in drive controllers. Multi-turn absolute tracking preserves position counts across power cycles, and frame size 075 suits machines that need smooth motion with moderate rotor inertia.
An electrically released holding brake supplies 23 Nm of static torque to secure axes when power is removed. The brake helps hold loads at standstill when the servo is not energized. The housing carries an IP65 rating that blocks dust and low-pressure water jets from the windings and optical feedback components. Power is transmitted through a shaft with keyway, which provides positive mechanical engagement under cyclic load. Class 155 insulation supports elevated coil temperatures, and continuous operation is permitted within an ambient range of 0 to 40 °C without derating. This thermal class supports sustained operation in enclosed machine sections where heat can build during extended duty.
