Product Description:
The MSK070C-0300-NN-M1-AG1-NNAN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Serving as a compact actuator for positioning and velocity control in automated machinery, the unit converts drive current into precisely regulated torque that can be coupled to ball-screw, belt, or gear stages. By integrating encoder feedback and an electrically released brake, the motor supports closed-loop performance and standstill holding in packaging, printing, and assembly equipment. Its synchronous design allows responsive speed regulation and accurate repeatability in axes that start, stop, and reverse frequently. This makes it suitable for compact machine layouts where consistent torque response and reliable position control are required throughout repeated production cycles.
The motor uses a reduced run-out design in a size 070 frame with a length C housing, which helps minimize radial error at the plain shaft. Heat is removed through natural convection, so no external fan or liquid manifold is required when the ambient temperature remains within 0 to 40 °C. The enclosure has an IP65 rating to resist dust and low-pressure water jets, and insulation class 155 supports winding temperatures suited to continuous duty. Power enters through the A-side connector, and winding code 0300 matches the electrical characteristics expected by compatible IndraDrive controllers. The passive cooling arrangement and sealed housing also reduce the need for auxiliary hardware around the motor.
Position and speed are resolved by an optical feedback system that uses a Hiperface interface with 128 signal periods per mechanical revolution. The encoder is a multiturn absolute type, so the drive can retain up to 4096 shaft turns without battery backup after power loss. The holding brake is rated at 23 Nm and is spring applied and electrically released, allowing the axis to hold vertical or unbalanced loads when the controller is disabled. This arrangement is useful on machines that need retained position data after an interruption and controlled holding at standstill.
