Product Description:

The MSK101E-0450-NN-M2-BP0-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It occupies frame size 101 with length code E and is intended to drive machinery that requires precise positioning in packaging lines, pick-and-place stations, and forming presses. A design focus on increased concentricity keeps shaft runout low, which helps reduce cyclic loading on couplings and bearings during closed-loop motion control. This supports smooth rotation during indexing moves, synchronized transport, and repeated start-stop operation.

This motor disperses heat through natural convection, allowing layouts that avoid forced-air ducting. A housing sealed to IP65 blocks dust and water jets so the unit can be mounted near process equipment without a separate enclosure. Feedback is handled by an optical encoder that uses the EnDat2.1 digital interface and delivers 2048 signal periods per mechanical revolution, supporting fine velocity and position regulation. The optical feedback channel gives the drive continuous rotor-position data for accurate control across changing loads and speeds. The B-side power connector helps simplify cable routing when the drive is located behind the motor, and the unit is supplied without a holding brake, so a stopped axis must be secured by drive torque or external hardware when power is removed.

The encoder stores position through a multiturn absolute counting system, retaining revolution data across 4096 turns even if the shaft is moved manually. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, which suits typical industrial indoor installations. Mechanical output is transferred through a shaft with keyway, allowing secure torque transmission to pulleys, couplings, or gearboxes. The keyed shaft also helps prevent slip in applications that use rigid hubs or timing elements. Thermal endurance follows insulation class 155, and winding code 0450 sets the stator copper section and resistance values expected by the matching drive.
