Product Description:
The MSK043C-0600-NN-M3-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for industrial automation, it converts drive current into controlled rotary torque for feed axes, pick-and-place heads, and auxiliary spindles that require repeatable positioning. When paired with an IndraDrive power stage, its Hiperface feedback channel supports real-time monitoring of speed and position, making the motor suitable for packaging machines, printing lines, and other multi-axis motion systems where accurate cycle-to-cycle response is important.
Cooling is handled by natural convection, eliminating the need for external fans and keeping the installation simple. The enclosure carries an IP65 rating, so dust is kept out and low-pressure water jets do not interfere with operation. An allowable ambient range of 0–40 °C fits typical machine and cabinet conditions in factory settings. The motor uses a plain shaft, which simplifies coupling to gearheads or belt drives that do not require a keyed connection. Its 155 insulation class supports the winding temperatures associated with continuous cyclic duty. Motor size 043, length C, the standard design, and winding code 0600 match the electrical characteristics expected by compatible 400 V IndraDrive amplifiers.
A rotatable 240° encoder connector and a Hiperface serial interface connect the feedback system to the drive. Inside the motor, a multi-turn absolute encoder tracks up to 4096 revolutions, so position data remain available after power loss. The feedback system uses capacitive measurement and provides 16 signal periods, which the controller can interpolate for precise angle evaluation. For load-holding requirements, the electrically released brake supplies 4 Nm of static torque, allowing vertical or suspended axes to remain parked when the drive is disabled. This combination of absolute feedback and holding brake support is useful in machines that must resume operation with predictable axis status after brief stops or power interruptions.
