Product Description:
The MSK100B-0300-NN-M2-AP0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning and velocity tasks, the unit converts commanded drive currents into precise mechanical motion for packaging lines, gantry axes, and general automation equipment. Its electromechanical design supports direct integration with IndraDrive controllers, providing high torque density while maintaining compact external dimensions in multi-axis assemblies. This layout suits machines that need repeatable motion without requiring a large motor footprint.
Heat is removed by natural convection, so the motor relies on ambient airflow rather than fans or liquid cooling. The motor carries an IP65 enclosure rating that prevents dust ingress and resists water jets encountered on production floors. Power is delivered through a shaft with keyway, giving slip-free coupling to pulleys or gear sets. Frame code 100 indicates a stator diameter and inertia level suited to mid-range axis loads, while increased concentricity minimizes radial runout for smoother rotation. The motor also uses a power connector on the A-side, and length code B sets the overall package depth.
Position feedback is handled by an EnDat2.1 optical interface that transmits absolute position and diagnostic data to the drive over a bidirectional serial channel. The optical sensor produces 2048 signal periods, and because it is multiturn absolute, the controller receives distinct revolution counts without needing a homing sequence after power-up. The motor is supplied without a holding brake, so external mechanics or drive torque must secure loads when power is removed. Thermal capability is supported by insulation class 155, and continuous operation is specified for ambient temperatures from 0 to 40 °C. A winding code of 0300 corresponds to the electrical resistance and inductance values used by compatible drives.
Frequently Asked Questions about MSK100B-0300-NN-M2-AP0-RNNN:
