Product Description:
The MSK100C-0300-NN-M2-BP2-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is built in motor size 100 with C length. A shaft with a keyway lets the rotor output couple rigidly to machine elements, and winding code 0300 indicates the electromagnetic layout used with the assigned drive inverter. Designed for industrial automation, the motor supplies commanded torque and position feedback to packaging, metal-forming, and handling axes that rely on high-accuracy closed-loop control.
Heat is removed by natural convection, so the housing fins dissipate losses without external fans or coolant. The enclosure carries an IP65 rating, which blocks dust ingress and resists water jets during washdown cycles. An electrically released holding brake provides 70 Nm of static torque, helping keep vertical loads secure when power is removed. The motor uses an EnDat2.1 feedback interface, and the rotor and bearing system are machined for increased concentricity to minimize runout at high speeds. This combination supports accurate motion control in machinery that requires stable positioning and repeatable rotation.
The optical encoder delivers 2048 signal periods per revolution and operates as a multiturn absolute device, so the controller can read an unambiguous position value after each power cycle. With the power connector located on the B-side, cable routing can follow standard MSK layouts inside tight equipment frames. The motor operates in ambient temperatures from 0 to 40 °C, and its insulation system is rated for Class 155 to withstand winding temperatures that occur in continuous duty. These operating and connection features support use on automated axes where reliable feedback and compact cable management are important.
