Product Description:
The MSK076C-0300-NN-S2-UP0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied through the MSK IndraDyn S Synchronous Motors series. In factory automation, it provides precise rotary motion for drive axes, allowing tight position and velocity control in packaging, printing, and metal-cutting equipment. Its synchronous design supports fast torque response during acceleration, deceleration, and contouring moves. The C-length housing gives the motor a moderate installation depth while preserving torque capacity for its frame size.
Heat produced by the stator is removed through natural convection, so the housing should be mounted where air can circulate freely without auxiliary fans. Because cooling is passive, unobstructed space around the motor helps dissipate copper and iron losses during continuous operation. The mechanical build follows an increased concentricity design that minimizes shaft runout and supports stable encoder alignment. A keyed mechanical interface is provided by the shaft with a keyway, which supports secure torque transfer to gearboxes, pulleys, or couplings. The motor uses size code 076, and winding code 0300 marks the coil set matched to the connected drive controller.
Feedback connections use a connector that is rotatable through 240°, allowing the cable exit direction to be adjusted during installation. Position data is transmitted over the EnDat2.1 serial interface, and the optical scanning head produces 2048 signal periods per mechanical revolution for fine interpolation inside the drive. The encoder is a single-turn unit, so absolute position is retained for one revolution without referencing, although axes that move beyond that span still require homing. Optical sensing helps maintain clean signal transmission at high speed and supports stable feedback quality during rapid motion changes. The motor is supplied without a holding brake, so an external brake or drive-applied holding torque is needed when a load must remain fixed at standstill.
