Product Description:
The MSK070C-0300-NN-M2-UG0-RNNN is a three-phase synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It connects to IndraDrive amplifiers and converts electrical power into tightly regulated rotary motion for linear stages, rotary tables, and pick-and-place gantries used in automated cells. A high-resolution optical feedback device and a dynamically optimized rotor support rapid positioning moves while maintaining the accuracy required in packaging, assembly, and metal-forming applications. This combination also helps the axis remain stable during frequent starts, stops, and reversals.
Thermal management relies on natural convection, eliminating the need for external blowers and simplifying enclosure layouts. The housing follows frame size 070, while the active core length code C balances torque output against installation depth for machinery with restricted mounting space. Winding code 0300 sets the electrical characteristics expected by compatible IndraDrive controller settings. A plain shaft simplifies clamp coupling, and an increased concentricity tolerance keeps radial runout low, which helps protect bearings and reduce vibration during higher-speed duty. This shaft style also suits friction-locked hubs and pulleys where low backlash is important.
Feedback uses a connector that is rotatable through 240°, allowing the cable to be routed toward either side of the machine frame and reducing sharp bends near the housing. Position data travels over the EnDat2.1 digital interface; within one mechanical revolution the optical scanner resolves 2048 signal periods and maintains multi-revolution information as a multiturn absolute value for power-off reference. Because the motor is supplied without a holding brake, static axis retention must be provided by drive torque or an external lock. The optical sensing method resists mechanical wear, and the absolute position data can shorten restart sequences when the control system uses stored position information.
