Product Description:

The MSK070E-0300-NN-M1-BG0-NNAN is a synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It supplies precise rotary motion for industrial automation axes such as packaging machinery, transfer units, and handling systems that require repeatable positioning. Its compact construction and integrated electronic feedback support closed-loop operation without requiring a larger installation envelope, which helps the motor fit into tightly packed machine layouts.

Heat generated by the windings is removed through natural convection, so no external fan or liquid circuit is required. The housing has an IP65 rating that helps seal internal parts against dust and low-pressure water jets, making the motor suitable for mounting directly on machinery. A plain shaft supports direct coupling to gearboxes or belt pulleys, and the power connector is mounted on the B-side to simplify cable routing in multi-axis assemblies. The unit operates in ambient temperatures from 0–40 °C without derating, and its winding insulation is in class 155 for sustained thermal endurance. It is supplied without a holding brake, so a vertical axis requires external load retention when power is removed.

The feedback system uses a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution. With multiturn absolute functionality, the drive can retain shaft position information across power cycles without relying on external reference switches. This arrangement supports accurate contouring at high speed while also improving startup behavior after a shutdown. Winding code 0300 indicates the stator characteristics used by the matching IndraDrive controller, helping the drive respond predictably to current commands. The motor balances a compact frame with enough torque capability for indexing tables and small gantries where stable motion and space efficiency are both important.
