Product Description:

The MSK101D-0450-FN-M1-AG3-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This motor converts the controlled three-phase output of an IndraDrive amplifier into mechanical rotation that can index pallets, synchronize packaging shafts, or drive articulated axes in automated cells. By pairing a large 101 frame size with the D-length stack, the unit delivers the continuous torque needed for medium-to-high inertia loads while remaining compact for cabinet-side mounting.

Heat generated in the stator is removed by liquid cooling, which maintains a low thermal gradient and supports higher continuous current than air-cooled equivalents. The optical encoder supplies 128 signal periods per turn and communicates through Hiperface, giving the drive high-resolution position and speed data. Its multi-turn memory tracks revolutions without battery support, so absolute position is preserved after shutdown. An electrically released holding brake provides 120 Nm of static torque, keeping vertical loads safely stopped when power is removed. A cast housing sealed to IP65 prevents dust ingress and water jets from reaching the windings. This standard design variant uses the 101 frame, D length, and routes power through an A-side connector to simplify cable runs in axis modules.

The remaining characteristics cover environmental limits and mechanical interfacing. Continuous duty is specified for ambient temperatures from 0–40 °C, accommodating most production floors without supplemental cooling. A plain shaft with a ground surface accepts compliant couplings or shrink disks, minimizing concentricity errors. Windings built to thermal class 155 withstand higher copper temperatures before insulation degradation, which is useful in applications with frequent peak cycles. Electrical constants assigned by winding code 0450 allow the drive to apply correct current limits and field-oriented control parameters.
