Product Description:

The MSK101D-0300-FN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In multi-axis automation, this motor functions as a precise torque and position source, pairing with Rexroth drive controllers to move tooling, gantries, or transfer arms in real time. It converts electrical drive commands into rotary motion with the fast response expected in servo applications. It is suited for axes that require synchronized motion and accurate positioning during repeated production cycles. Because the motor is supplied without a holding brake, stationary loads must be secured by drive torque or an external clamp.

The frame size of 101 establishes the mounting geometry, and the length code of D indicates the active stack height for continuous torque output. A shaft with keyway provides positive mechanical coupling, while the standard design supports consistent installation within the series. Heat is removed through a closed-loop liquid cooling circuit, allowing high continuous current in thermally dense machines. Winding code 0300 sets the motor’s voltage and current constants used with IndraDrive inverters. Power is routed through a connector on the B-side, which helps when cables exit toward the rear of the cabinet.

Rotor position feedback is generated by an optical encoder that communicates over the Hiperface interface. The sensing element is optical, which helps keep the signal path resistant to magnetic interference. Resolution is 128 signal periods per revolution, and the feedback is single-turn, so absolute position is retained within one mechanical turn. The feedback channel also carries stored motor information to the drive, which supports correct startup behavior and consistent motion control. This arrangement is well suited for packaging, printing, and material-handling machinery that depends on repeatable position feedback.
