Product Description:

The MSK101D-0450-NN-M1-BP2-NNNN is a three-phase IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Inside an automated cell, this motor converts command currents from an IndraDrive amplifier into precise torque and speed so indexing tables, gantries, or tool spindles can reach programmed positions under closed-loop control. Its integrated encoder supplies absolute position data to the drive controller, and the built-in holding brake secures the axis when power is removed. This arrangement supports controlled motion during operation and stable holding at standstill.

Thermal behavior relies on natural convection. The cooling code FN means the mounting location must allow unrestricted ambient airflow, so no fans or liquid circuits are required. The unit uses the standard design, has frame size 101 and length designation D, and winding code 0450 matches medium-current IndraDrive inverters. A power connector on the B-side separates high-power conductors from feedback cabling. Position feedback is delivered over the Hiperface interface, where an encoder with 128 signal periods per revolution uses an optical scanning principle to capture fine incremental edges. Because the sensor is multi-turn absolute, the shaft angle and complete turn count remain valid after shutdown. An electrically released brake rated at 70 Nm applies when the drive is disabled, providing static holding torque for vertical or safety-critical axes. Insulation class 155 supports elevated winding temperatures during cyclic duty.

The standard housing keeps contaminants out with an IP65 protection rating, so installation beside coolant lines or dusty conveyors is acceptable. Rated operation is limited to an ambient range of 0 to 40 °C, matching the natural-convection profile and the thermal endurance of class 155 insulation. Drive torque is transmitted through a shaft with a keyway, enabling straightforward coupling to pulleys, gearboxes, or rigid hubs without relying on friction fit alone. The output arrangement supports positive torque transfer when the motor is connected to machine elements that must resist slip.
