Product Description:
The MSK076C-0300-NN-M1-UP0-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat and supplied as part of the MSK IndraDyn S Synchronous Motors series. It is engineered to supply tightly regulated rotary motion for positioning axes and continuous-duty drives in automated machinery, where a feedback-ready AC motor must link directly with a digital drive controller.
This model relies on natural convection to move heat from the stator housing into the surrounding air, so no external fan or liquid circuit is required. Feedback signals are exchanged over the Hiperface protocol, enabling digital drive controllers to read incremental and absolute data through a single hybrid cable. Inside the encoder, the scale delivers 128 signal periods per mechanical revolution, allowing fine interpolation of speed and position. Mechanical power is transferred through a shaft with keyway, which supplies positive engagement with couplings or pulleys and resists slip under repetitive torque cycling. Electrical behavior is governed by winding specification 0300; that code defines the resistance, inductance, and voltage constants chosen for medium-torque, medium-speed applications.
An optical scanning system is used in the feedback unit, so magnetic fields from brakes or adjacent servomotors do not distort position data. The plug for the sensing electronics is rotatable, 240°, giving installers freedom to point the cable upward, sideways, or downward without stressing conductors. Form factor is identified by length code C and frame size 076, a combination that balances continuous torque against cabinet depth when the motor is mounted behind a machine panel. Because the unit ships without a holding brake, designers must retain load position through drive torque or an external clamp during power loss. A multiturn absolute encoder records shaft turns across power cycles, and the standard design variant simplifies spare-part substitution across the series.
