Product Description:

The MSK101D-0450-NN-M3-BG2-NNNN synchronous motor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servo motor, it converts drive current into controlled torque and speed for automated positioning axes. Within machine tools, packaging lines, and material-handling stations, it is suited for repeated motion tasks that require accurate tracking of commanded movement. The motor is built in frame size 101 with length code D, and its standard housing includes an electrically released brake to hold the load when the drive is disabled.

The feedback system uses a Hiperface interface, and the encoder provides 16 signal periods per revolution through a capacitive measuring element for stable position data in precision motion loops. Brake torque is rated at 70 Nm, which supports load holding on vertical axes without external clamps. The housing is sealed to IP65, helping keep dust and water jets away from the internal windings. Winding code 0450 corresponds to the electrical characteristics used with compatible IndraDrive amplifiers, while insulation system class 155 supports continuous conductor temperatures associated with cyclic servo duty. The B-side power connector separates high-current cabling from encoder wiring to reduce crosstalk.

Position data are retained over multiple revolutions through the encoder’s multi-turn absolute capability, so the controller can identify shaft position again after power is restored. This allows the axis to return to controlled operation after a power interruption without a full reference run in many applications. The motor is intended for ambient temperatures from 0 to 40 °C. Heat is removed by natural convection, so no auxiliary fan is required. Output torque is transmitted through a plain shaft for use with suitable clamping couplings matched to the driven load.
