The R911335121 (MSK100A-0450-NN-M1-AG0-NNNN) is a synchronous servo motor from the IndraDyn S series, designed for high-precision motion applications. It delivers a maximum torque of 54 Nm and operates with a peak current of 54 A. The unit features an IP65-rated housing for resistance to dust and water, and is equipped with a plain output shaft utilizing a sealing ring. The motor achieves up to 6000 rpm with natural convection cooling and has four pole pairs. An A-side electrical connector and a multiturn absolute optical encoder with Hiperface interface (128 signal periods resolution) enable precise rotor position detection. The continuous torque at a standstill (100 K) is 17.0 Nm with a continuous current of 13.6 A. The sound pressure level is 75 dB, and the torque constant is 1.45 Nm/A. The device operates in ambient temperatures from 0 to +40°C and has a mass of 23 kg. Holding brakes are not included.

Frequently Asked Questions

How does the Hiperface optical multiturn encoder (128 signal periods) help on MSK100A-0450-NN-M1-AG0-NNNN?

The multiturn absolute feedback preserves shaft position across power cycles, avoiding homing and improving recovery after stops. Its 128-period Hiperface interface enhances commutation accuracy and speed loop linearity for precise positioning from standstill through rated speed.

Why specify natural-convection cooling on MSK100A-0450-NN-M1-AG0-NNNN, and when is it advantageous?

The fanless cooling cuts maintenance points and contamination risk for favoring hygienic or particulate-sensitive zones and vertical axis layouts with efficient heat paths. It’s well-suited where thermal loading stays within S1/S3 envelopes defined for the MSK family’s available cooling options.

How does the 7,800 mH winding inductivity affect servo performance and drive sizing?

The higher phase inductivity attenuates current ripple and PWM harmonics for easing drive bandwidth requirements and thermal cycling of the copper. It promotes smoother torque at low speed and reduces need for extremely fast current controllers at the amplifier.

Why choose the plain-shaft variant here, and how does it influence coupling design?

The plain shaft supports backlash-free, clamp-style or shrink-disc couplings for minimizing eccentricity and simplifying alignment on precision axes. It also allows quick interchange during service without key/keyway tolerancing constraints to aid consistent concentricity.

What protection/insulation and ambient limits apply to MSK100A-0450-NN-M1-AG0-NNNN?

The IP65 ingress protection with class 155 insulation is listed for supporting typical factory environments with proper cable/connector sealing. It indicates 0…40 °C ambient that aligns with many packaging and machine-tool enclosures when airflow is maintained.
