Product Description:

The MSK071E-0200-NN-M1-UG2-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 motion tasks in industrial automation, where the motor supplies precise torque and speed for packaging lines, robotic joints, and CNC feed axes. When used with a compatible drive controller, it supports accurate path tracking and steady speed regulation during synchronized multi-axis motion. Its compact servo design also suits machines that need responsive movement without adding unnecessary bulk to the axis.

At the mechanical level, the motor uses the 071 frame size and the compact E length. The electromagnetic layout is matched to winding code 0200, which fits the motor’s intended operating range in this housing. Thermal management is passive, with a ribbed housing for natural convection, and the data sheet notes Cooling FN, which means no forced air or liquid jacket is required under rated load. Position information is routed through a rotatable 240° encoder connector that carries a Hiperface signal. The optical feedback system provides 128 signal periods per revolution, giving the drive a stable basis for interpolation, commutation, and speed regulation. The rotatable connector also helps with cable routing when the motor is installed in tight machine spaces.

The feedback system stores position over multiple mechanical turns, and this function is listed as Multiturn Absolute. An electrically released brake provides 30 Nm of holding torque, which helps keep vertical or indexing axes stationary when power is removed. Torque is transmitted through a plain shaft, which suits clamp couplings and shrink-disc connections used on compact servo axes. Because the controller can retain position information after restart, the axis can return to operation without a separate homing cycle in many applications. This arrangement is useful where repeatable stopping behavior and stable restart positioning are required during normal machine operation.
