Product Description:
The MSK071C-0450-NN-M3-UP1-NNNN servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is a synchronous servo motor used for controlled torque output and precise position feedback in automated conveyors, pick-and-place stations, and packaging axes. The integrated multi-turn absolute encoder preserves shaft position across power cycles, supporting coordinated motion without a homing routine after startup. This arrangement helps the connected drive maintain accurate axis control during indexing, positioning, and repeated start-stop movement. Its closed-loop design also suits applications that need stable low-speed motion as well as accurate positioning at higher travel rates.
Cooling relies on natural convection, so no external fan is required and heat dissipates through the housing during continuous duty. The encoder communicates through the Hiperface interface, letting the drive read position data and electronic nameplate information through one cable connection. An electrically released holding brake provides 23 Nm of static torque to secure vertical loads when power is removed. The enclosure meets IP65, which helps block dust ingress and low-pressure water jets, and safe operation is specified within an ambient range of 0–40 °C. This arrangement keeps the exterior free of separate blower components and reduces the amount of wiring around the motor body.
The shaft is a shaft with keyway, giving positive mechanical coupling to pulleys or couplings without relying only on clamping force. The encoder uses capacitive scanning at 16 signal periods, and its connector can rotate 240° to simplify cable routing inside tight machine frames. The rotating connector also helps reduce cable strain where the motor is mounted close to guards, plates, or neighboring axes. With motor size 071 and length code C, the frame offers a compact footprint while still supporting the installed winding for the required torque constant. Internal insulation is class 155, which supports the thermal demands created by repeated acceleration, deceleration, and holding cycles in industrial service.
