Product Description:

The MSK101D-0300-NN-M1-LG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks that require accurate speed control and repeatable positioning in automated equipment. The motor combines an absolute optical encoder with an integrated holding brake, so an axis can keep position information after a power interruption and remain secured when the drive is disabled.

Cooling is provided by natural convection, so heat is released through the motor housing without an external blower. The enclosure carries an IP65 rating, which protects internal components against dust and low-pressure water spray in typical industrial environments. An electrically released holding brake provides 70 Nm of static torque to keep the shaft from moving at standstill. Rotor feedback is transmitted through the Hiperface interface, and the encoder delivers 128 signal periods per mechanical revolution for precise commutation and position tracking. The encoder is multi-turn, so the drive can retain absolute position information over multiple revolutions instead of requiring a homing cycle after every restart.

Winding code 0300 identifies the electrical winding used for this motor and matches the operating range expected by the connected drive controller. Insulation class 155 supports winding temperatures up to 155 °C, and the permitted ambient operating range is 0-40 °C when the motor is used within its intended conditions. The motor has a plain shaft for direct coupling, and the standard mechanical layout follows size 101 with length D. Power and feedback connections are arranged through the left-side connector, which helps with cable routing when separation from adjacent machine elements is needed. This version includes the integrated brake and absolute optical feedback in a standard housing layout.
