Product Description:
The MSK076C-0300-NN-M1-UP1-NNNN is a precision servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within automated assembly lines, packaging stations, and material-handling axes, the unit converts drive commands from Rexroth controllers into regulated rotary motion that holds position and velocity with high repeatability. Its mechanical keyway shaft transmits torque directly to couplings or pulleys while the integrated encoder feeds back absolute position, enabling closed-loop control essential for coordinated multi-axis automation. This arrangement supports synchronized indexing, controlled acceleration, and accurate stopping on axes that must move in step with adjacent machine functions.
Thermal behavior is managed through natural convection, so the motor can be mounted without external fans, and heat moves from the stator housing to ambient air. Position feedback relies on an optical scanning system that tracks a coded disk with 128 signal periods per revolution, providing fine resolution before interpolation. Data exchange between the encoder and the drive takes place over the Hiperface interface, which carries both incremental and absolute information on a two-wire pair. Because the encoder is a multiturn absolute design, it counts full revolutions even when power is removed, eliminating homing routines after shutdowns. The feedback arrangement gives the controller continuous rotor angle information for commutation and position regulation throughout operation.
During power-off conditions, an electrically released brake supplies 11 Nm of holding torque to keep vertical or load-bearing axes stationary until motion is commanded again. This unit has motor length C in frame size 076, giving a compact footprint that balances inertia with continuous torque capability. Winding code 0300 corresponds to the stator's electrical characteristics so the drive can apply appropriate current limits and field-oriented control parameters. The brake is intended to hold the axis at standstill when external motion is not desired.
