Product Description:

Bosch Rexroth Indramat manufactures the MSK101D-0450-FN-M1-BG2-NNNN, an IndraDyn S synchronous servo motor in the MSK IndraDyn S Synchronous Motors series. The unit converts drive current into precise rotary motion for positioning axes, gantries, and processing spindles on automated lines. Its D-length housing combines a compact footprint with integrated cooling passages and high-resolution feedback for continuous-duty operation. This configuration is suited to applications that need accurate speed regulation and repeatable positioning under changing load conditions.

The motor uses liquid cooling, with coolant circulating through the stator jacket to remove heat and support full-load operation in confined installations. Feedback is transferred through the Hiperface serial interface from an optical encoder that provides 128 signal periods per revolution and retains multi-turn absolute position data. During power loss, an electrically released brake provides 70 Nm of holding torque to secure vertical or high-inertia loads. A molded housing, sealed cable entries, and shaft seals give the motor an IP65 rating for use near dusty or wet process areas. The motor also has standard mechanical construction, motor length D, a B-side power connector, and winding code 0450 for use with matching drive systems.

The motor has Motor Size 101, which uses the flange, pilot, and bolt pattern common to high-torque axes and supports connection to gearheads or belt pulleys. Continuous ratings apply at ambient temperatures from 0–40 °C, and the windings use thermal class 155 insulation for prolonged duty. Power is transmitted through a plain shaft, which supports clamp or shrink-fit hubs where low backlash is required. This shaft style also avoids the need for keyed connections in applications that use friction-based shaft attachments.
