Product Description:

The MSK070C-0150-NN-S1-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts controlled three-phase power from an IndraDrive inverter into rotary motion that can be used in speed, torque, or position loops. This unit is used in packaging lines, gantry axes, and material-handling modules that demand repeatable moves and rapid reversals. Its synchronous design allows the paired drive to regulate rotor motion closely during indexing, transfer, and other coordinated machine movements.

The frame size of 070 indicates the motor's stator diameter, while length class C increases the active iron to raise continuous torque without changing the mounting footprint. Winding code 0150 matches the electrical characteristics to compatible drive outputs in the midsize current range. Heat is removed by natural convection, so no external fan or liquid lines are required. An electrically released holding brake provides 23 Nm of static torque to keep vertical or suspended axes in place during power loss. A plain shaft transmits torque through friction-fit couplings, which helps avoid keyway backlash. That shaft style is commonly used with clamp-style hubs or similar couplings that rely on surface contact. The motor connectors are mounted on a housing that can rotate 240 degrees for flexible cable routing.

Servo feedback is provided by a Hiperface optical encoder integrated in the rear end bell. The encoder tracks 128 signal periods per mechanical revolution, and the drive interpolates these signals for fine position control. Because the sensor is optical, it is not affected by demagnetization and maintains stable accuracy over long operating periods. The encoder is a singleturn type, so it delivers an absolute position value within one revolution. The feedback channel also supplies the rotor-angle information needed for commutation and closed-loop positioning during repeated acceleration and deceleration.
