Product Description:

The MSK101D-0450-NN-S2-BP0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as the prime mover in numerically controlled axes. It converts electrical commands from a Rexroth drive into rotational motion with tightly regulated speed and position for automated handling, tooling, and assembly stations.

The motor has a protection rating of IP65, which seals the housing against dust and low-pressure water jets so the motor can be mounted directly on machinery. Heat is removed through natural convection, eliminating external blowers and allowing installation in enclosed spaces. The stator windings remain within their rated temperature range throughout an ambient range of 0 to 40 °C, preventing derating in typical shop floor climates. For feedback, the motor integrates an optical encoder that communicates via the EnDat2.1 interface. This encoder delivers 2048 signal periods per mechanical revolution, providing fine angular resolution that the controller uses to hold velocity and position tolerances during rapid indexing.

A shaft with a keyway transmits torque without slip to pulleys or gearboxes, and the rotor is balanced for increased concentricity to minimize vibration in high-speed cycles. Because the encoder is single-turn, absolute position is retained over one revolution, which simplifies homing routines on startup. Thermal integrity is reinforced by insulation class 155, permitting winding temperatures up to 155 °C under intermittent load peaks. The electromagnetic circuit uses winding code 0450, matching the motor to drives that can supply its rated current and voltage. Additional characteristics include motor size 101 with length code D, a B-side power connector that keeps cabling clear of the load end, and delivery without a holding brake, which allows the use of an external clamping device when static locking is required.
