Product Description:
The MSK101C-0300-NN-M2-BG0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat and placed within the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC motor, it converts drive current from a servo amplifier into tightly regulated rotary motion for positioning axes, pick-and-place gantries, and similar industrial automation tasks that require closed-loop speed and torque control. Its electrical and mechanical interfaces follow the common MSK frame format, which supports straightforward integration into automated equipment that uses this motor platform.
Thermal management is handled by natural convection, so the housing relies on ambient airflow instead of forced fans. The aluminum frame carries an IP65 sealing grade that blocks dust ingress and water jets, allowing mounting near the driven mechanism. Position feedback is generated by an optical measuring system that uses an EnDat2.1 serial interface. The sensor delivers 2048 signal periods per revolution and records absolute position over multiple turns. With this multiturn absolute feedback, the drive controller can recover shaft angle immediately after power is restored, which helps the axis return to operation without an additional reference run.
The motor uses winding code 0300 in the 101 frame with C length, giving a balanced ratio of torque to mass for medium-power axes. Rotor machining with increased concentricity helps minimize radial runout on the plain shaft, which mates directly with precision couplings. Electrical power enters through the B-side connector, which keeps motor leads separate from the encoder cable bundle and supports orderly cable routing. The motor is supplied without a holding brake, so static load retention must be handled by the drive or external clamps. Insulation class 155 supports continuous operation within the specified ambient range of 0–40 °C without thermal degradation when the motor is used under appropriate operating conditions.
Frequently Asked Questions about MSK101C-0300-NN-M2-BG0-RNNN:
Q: How is the MSK101C-0300-NN-M2-BG0-RNNN motor cooled?
A: The MSK101C-0300-NN-M2-BG0-RNNN motor uses natural convection cooling, which means it operates without the need for external fans or forced cooling systems.
Q: What encoder interface does the MSK101C-0300-NN-M2-BG0-RNNN feature?
A: This servomotor is equipped with an EnDat2.1 encoder interface for precise positioning feedback.
Q: What type of shaft does the MSK101C-0300-NN-M2-BG0-RNNN motor have?
A: The MSK101C-0300-NN-M2-BG0-RNNN has a plain shaft design, allowing it to be easily adapted to various coupling requirements.
Q: Does the MSK101C-0300-NN-M2-BG0-RNNN include a holding brake?
A: This model is produced without a holding brake, so it will not maintain position without external force when powered off.
Q: What is the protection rating of the MSK101C-0300-NN-M2-BG0-RNNN motor?
A: The MSK101C-0300-NN-M2-BG0-RNNN motor offers an IP65 protection rating, making it resistant to dust and water jets from any direction.
