The Bosch Rexroth synchronous servomotor R911378738 (MSK101C-0450-FN-S1-LP2-NNNN) features a B5 frame size per EN 60034-7, RAL 9005 black coating, and a 10 x 8 x 45 mm output keyway shaft in accordance with DIN 6885-A. It utilizes a Hiperface optical singleturn encoder with 128 signal periods for position and speed feedback. The unit incorporates liquid cooling (Cooling FN), left-side power connector, and supports transmission elements meeting 94/9/EG. Motor length is C, and size is 101; winding code is 0450. Continuous current at standstill (100 K) is 28.6 A with continuous torque at 36.5 Nm. Maximum current is 113.0 A, maximum torque is 110.0 Nm, and winding inductivity measures 3,300 mH. The shaft direction may be up or down. The motor includes an electrically-released 70 Nm holding brake, which is not suitable for service braking. Installation altitude must not exceed 3000 m and the unit should be handled to avoid explosive hazards during connection. Compatibility validation is required when introducing new cleansers or lubricants.

Frequently Asked Questions

What advantages does the singleturn Hiperface optical encoder (128 signal periods) provide for MSK101C-0450-FN-S1-LP2-NNNN in closed-loop motion?

The Hiperface supplies absolute position within one revolution plus high-fidelity sine/cosine feedback for smooth commutation and velocity control. Its interface also transports parameter/diagnostic data to the drive for aiding commissioning and condition monitoring.

Why specify a B5 flange mounting for this servomotor, and where is it typically used?

The B5 (per EN 60034-7) provides a rigid face-mount interface that maintains alignment under radial/axial loads. It’s common on machine tools, packaging axes and printing units requiring accurate gearhead or bell-housing interfaces.

How does the 70 Nm electrically released holding brake in MSK101C-0450-FN-S1-LP2-NNNN affect axis safety and homing?

The brake clamps the shaft without power for preventing back-driving on vertical or suspended loads during e-stop or power loss. Its electrically releasing enables controlled homing and reduces drift before encoder reference capture.

How does the 3,300 mH winding inductivity of MSK101C-0450-FN-S1-LP2-NNNN affect drive tuning and cabling choices?

Its higher inductivity moderates ripple current and eases current-loop stability to allow wider PWM filtering margins. It also makes the system less sensitive to cable parasitics, though proper shielding and grounding remain essential at high di/dt.

What are the implications of the left-side power connector orientation on cabinet layout and serviceability for MSK101C-0450-FN-S1-LP2-NNNN?

The left-side power simplifies routing on machines with mirrored or tandem axes and can reduce bend-radius conflicts near cable tracks. It also aids segregation of encoder and power harnesses to minimize coupling and EMC issues.

Internal Product Review

Bosch Rexroth Indramat develops the servo motor MSK101C-0450-FN-S1-LP2-NNNN with an integrated 70 Nm electrically released holding brake. It depends on liquid cooling and a singleturn Hiperface optical encoder (128 periods) for feedback. This motor uses a keyed shaft and supports B5 flange mounting. It delivers 36.5 Nm continuous, 110 Nm peak torque that makes it applicable in packaging, printing and machine tools.
