Product Description:
The MSK070C-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop axis control in industrial automation where precise torque delivery and accurate position feedback are required to coordinate gantries, packaging stations, and metal-cutting spindles. The rotatable 240° encoder connector eases cable routing in compact machine layouts.
This motor is cooled by natural convection, meaning heat is removed through surface radiation and ambient airflow without auxiliary fans; this simplifies cabinet layouts and eliminates moving cooling parts. The frame is categorized as size 070, a diameter class that sets the flange pattern and the compatible load inertia range. Electrical behavior is tied to winding code 0450, which sets the phase resistance, inductance, and rated speed used by the matching drive. Position data are transmitted through the Hiperface interface, allowing commutation, velocity, and absolute position information to travel over a single hybrid cable. Inside the encoder, an optical scanning method converts incremental and absolute tracks into digital signals with high immunity to magnetic disturbances.
The optical disk provides 128 signal periods per mechanical revolution; when interpolated by the drive, this supports sub-arcminute positioning accuracy. Multirevolution tracking is available because the sensing element is a multiturn absolute design, so axis position is retained after power loss and during emergency-stop events. A spring-applied, electrically released brake supplies 23 Nm of holding torque, allowing vertical loads or tooling tables to remain locked when the servo is disabled. Power transfer to the driven machine takes place through a shaft with keyway, giving a positive mechanical lock that resists slip during rapid reversals and high peak torques. The standard housing design allows direct integration into IP-rated machinery without special mounting adapters.
