Product Description:
The MSK070D-0300-NN-M1-UG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a permanent-magnet servomotor intended for precise closed-loop positioning and velocity control on packaging lines, handling robots, and other automated machinery. By integrating high-resolution feedback, the unit allows direct coupling to machine mechanics while maintaining the dynamic response demanded in multi-axis systems.
Thermal management is handled by natural convection, so the frame dissipates heat without external fans or liquid circuits. The housing uses the standard design of this series, and its frame corresponds to size 070, giving a stator diameter suitable for mid-range torque requirements. Overall axial build is identified by motor length code D, while electromagnetic characteristics are tied to winding code 0300; together these codes match the motor to Rexroth drive modules that supply the correct current and voltage. Position data is transferred through a Hiperface interface, enabling synchronous digital communication between the motor encoder and the drive controller. An optical scanning system resolves 128 signal periods per revolution, providing fine incremental data that supports smooth low-speed operation and accurate interpolation.
The feedback plug is rotatable through 240°, letting the connector be oriented to suit cable routing inside crowded cabinets. Absolute position is retained by a multi-turn absolute encoder that records multiple shaft revolutions, and its sensing principle is optical, which minimizes magnetic interference. An electrically released holding brake is integrated; it clamps the rotor with 23 Nm of torque, keeping vertical or suspended loads stationary when power is removed. The plain shaft profile eliminates keys or splines, reducing runout and facilitating coupling with backlash-free clamping hubs.
