Product Description:

The MSK071C-0450-FN-S1-UG0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. Intended for industrial automation, the unit converts drive current into precise rotary motion. It is suited for axes that require high positional accuracy in packaging lines, assembly stations, and material-handling gantries. In closed-loop systems, the motor works with a servo drive to maintain controlled speed, torque, and position during repeated motion cycles. Its synchronous design is well suited for applications that need repeatable starts, stops, and short settling times. This type of motor is often used where smooth acceleration and accurate motion response are required under changing loads.

Thermal management relies on liquid cooling, allowing the 071-frame stator to shed heat without external airflow and sustain continuous torque in tight enclosures. The housing carries an IP65 rating that seals the windings from dust and low-pressure water jets. Position feedback is generated by a Hiperface optical encoder that offers 128 signal periods per mechanical revolution, and its connector can rotate 240 degrees to simplify cable routing. The motor has a plain shaft for direct coupling to clamping hubs or gearboxes. Its C-length body accommodates the 0450 winding while keeping overall mass suitable for gantry-mounted axes, and the standard design variant omits optional dampers that would add inertia.

The motor uses the 0450 winding, which pairs with IndraDrive amplifiers for nominal currents associated with medium-torque duties. Safe operation is maintained between 0 to 40 °C, matching common cabinet or machine-frame environments. The windings use Class 155 insulation for thermal endurance during continuous overload cycles. The motor is supplied without a holding brake, so static load retention must be provided by the drive or by external mechanics. The single-turn encoder reports absolute position within one mechanical revolution, which suits applications that do not require multiturn position retention.
