Product Description:
The MSK070C-0450-NN-M1-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It operates as a precision actuator in industrial automation, converting regulated drive current into controlled rotary motion for packaging stations, handling modules, and CNC positioning axes. When paired with an IndraDrive controller, the motor supports closed-loop motion with repeatable torque response, stable velocity control, and accurate path tracking during frequent start-stop cycles.
Thermal management relies on natural convection, so the standard housing surface disperses loss heat without auxiliary fans and keeps installation requirements straightforward. A rotatable feedback plug simplifies wiring because the encoder connector offers a 240° rotation range, making cable routing easier in either mounting direction and reducing stress at the connector. Position data travels via Hiperface, and within every mechanical turn the sensor generates 128 signal periods for drive-side interpolation and smooth low-speed control. Because the scanning principle is optical, the feedback signal remains stable against rotor magnet temperature drift and surrounding electromagnetic interference. The C motor length and 070 frame size set the mechanical envelope and flange for medium-inertia axes that need moderate continuous torque.
The feedback element is a multiturn absolute variant, storing up to 4096 revolutions so the drive powers up with an immediate position reference and does not require a homing move after each restart. The motor is supplied without a holding brake, so static load retention must be handled by controlled torque or an external clamp when the axis is stopped. Power is transmitted through a shaft with keyway, which helps prevent slip when the motor is coupled to a gearbox or belt pulley. The internal three-phase stator uses the 0450 winding code, matching the electrical characteristics expected by 400 V class inverters and supporting the speed range associated with the C-length housing.
