Product Description:
The MSK030C-0900-NN-M1-UG1-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Serving as the actuation element in closed-loop motion systems, this motor delivers repeatable torque and position feedback for pick-and-place modules, gantry axes, and other automated machinery that requires coordinated multi-axis control. By integrating a high-resolution feedback device and an electrically released brake, the unit maintains commanded position during dynamic operation and standstill, supporting safe and accurate automation cycles in packaging, printing, and material-handling environments. Its compact format also suits machine layouts where drive components must fit into limited installation space.
Heat is removed by natural convection, so the housing must be placed where surrounding air can carry away losses without auxiliary fans. The encoder connector is rotatable through 240°, allowing the plug to align with cable exits and reduce bending stress. Position data travels over the Hiperface digital link, while internal sensing uses an optical head that scans a disc with 128 signal periods. This arrangement provides fine incremental counts and an absolute reference with low electrical noise. The digital feedback path also helps the connected drive maintain stable commutation and accurate position tracking.
The feedback device is a multi-turn absolute encoder, so the drive receives the rotor’s revolutions across power cycles without an external homing routine. For mechanical holding during shutdown, an electrically released brake delivers 1 Nm of static torque. Coupled with the plain shaft, this permits direct coupling to pinions or compliant couplers while the brake locks motion when supply voltage is removed. Winding code 0900 identifies the stator’s resistance and inductance values, allowing the drive to apply correct current limits for the natural-convection thermal path and the high-resolution optical encoder. The holding brake also supports axes that must remain stationary when power is off.
