Product Description:

The MSK050B-0450-NN-S1-BG0-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive controller output into controlled torque for positioning and speed regulation in automated production cells. Used with a compatible drive, it provides precise rotary motion for pick-and-place arms, forming presses, and packaging stations that require repeatable axis response. Its operating role is to translate electrical commands into stable motion so machines can maintain accuracy during cyclic production tasks.

In standard configuration, the motor relies on natural convection to remove heat, so the housing surface must remain unobstructed during operation. Its enclosure is rated IP65, which helps keep dust and low-pressure water jets away from internal components on the plant floor. Position feedback is generated by an encoder that uses the Hiperface digital interface, and the drive reads 128 signal periods per mechanical revolution for accurate commutation and speed control. The sensing method is optical, using light patterns and a code disk to produce electrical pulses with stable feedback behavior. This arrangement allows the motor and drive to exchange position data without external sensors and supports smooth regulation across typical servo duty cycles.

The encoder is configured as single-turn, so absolute position is retained within one revolution and a homing routine is still needed after multiple turns. Mechanical linkage is made through a plain shaft that suits backlash-free clamp couplings, and the power leads exit on the B-side of the stator for orderly cable routing. Operation is permitted from 0 to 40 °C, and the insulation system is class 155 for dependable winding protection at elevated temperatures. The motor follows the standard design with size 050, length B, and winding code 0450, and it is delivered without a holding brake when static load retention is handled by the drive or external mechanics. This layout fits applications where direct coupling, predictable cable routing, and controlled standstill behavior are more important than brake-assisted load holding.
