Product Description:

The MSK040C-0450-NN-M2-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop control of feed axes, tool heads, and pick-and-place modules where precise torque and speed regulation are required. Inside a compact frame, it combines optical feedback with a permanent-magnet rotor to provide accurate motion in space-limited equipment. This layout supports repeatable positioning and steady speed control in automated handling and processing systems.

This motor uses natural convection for cooling, so operation does not require forced airflow or liquid circuits. A die-cast housing rated at IP65 helps keep dust and low-pressure water jets away from the stator windings and encoder. Position data and motor data are exchanged through the EnDat2.1 bidirectional interface, which allows feedback and electronic motor information to travel on the same connection. The optical system generates 2048 signal periods per mechanical turn, and the drive can interpolate that signal for fine speed and position control. Because the encoder stores turns as a multi-turn absolute value, mechanical position remains available after power is removed without a battery. The motor is supplied without a holding brake, so a stationary load must be held by drive torque or an external device when the axis is stopped.

Size 040 laminations and frame length C keep the housing compact, while a rotatable feedback connector with 240° adjustment helps cable routing in tight enclosures. The output end uses a plain shaft, which suits backlash-free clamp couplings and keeps the shaft interface simple. Continuous duty is permitted in an ambient range of 0 to 40 °C, matching typical enclosed machine conditions. Insulation class 155 supports the thermal load created during repeated acceleration and deceleration cycles. Winding code 0450 corresponds to the electrical values used for this model and matches compatible IndraDrive amplifier settings. The connector can also be rotated to reduce cable strain when the motor is installed near panels or guarding.
