Product Description:

The MSK070E-0300-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It acts as a precision drive unit for industrial automation equipment, converting three-phase electrical input from an IndraDrive inverter into repeatable rotary motion. Typical duties include indexing conveyors, tool changers, and pick-and-place axes where accurate speed and position control are required.

The mechanical package starts with the 070 frame size, giving a flange diameter suited to medium torque requirements, and the length code E extends the stator stack so continuous power is increased without enlarging the footprint. Winding designation 0300 identifies the electrical characteristics that match drive modules capable of delivering the correct current while maintaining linear torque production. Thermal energy is dissipated by natural convection, removing the need for external fans or coolant plumbing and allowing the motor to rely on ambient airflow. For gravity-loaded axes, the electrically released brake supplies 23 Nm of holding torque to secure the load whenever power is removed.

Position feedback is handled by an optical encoder that communicates through Hiperface and produces 128 signal periods per mechanical turn. The device uses multi-turn absolute feedback, so it retains shaft position over multiple revolutions even after shutdown and eliminates the need for reference moves at startup. The rotatable 240° encoder connector eases cable orientation, and the unit follows the standard design classification for compatibility with existing mounting patterns. Drive torque is delivered through a shaft with a keyway, enabling positive engagement with couplings or gears and completing the mechanical interface.
