The Bosch Rexroth MPN R911338595 (MSK100B-0200-NN-S1-AP2-NNNN) is an IndraDyn S synchronous servomotor engineered for high-torque industrial applications. This model features a 100 motor size and B length, with a shaft including a keyway and an internal holding brake delivering 70 Nm of torque. The motor operates with natural convection cooling, a power connector on the A-side, and utilizes an optical singleturn Hiperface encoder with 128 signal periods for precise feedback. Key specifications include a continuous standstill current of 17.3 A, continuous torque at standstill of 33.0 Nm (both at 100 K), maximum current of 66.2 A, maximum torque of 102.0 Nm, and a winding inductivity of 7,600 mH. The unit is enclosed in an IP65-rated housing.

What positioning behavior comes from the optical Hiperface single-turn encoder (128 periods) on this unit?

The Hiperface’s sin/cos signals (128 periods/rev) allow the drive to interpolate fine increments for giving precise single-turn absolute position without batteries. It supports tight velocity/position loops when paired with IndraDrive controllers.

hat are the continuous and peak current/torque figures, and how should the drive be sized?

It offers 33.0 Nm at standstill (100 K) with 17.3 A, while its peak torque is 102 Nm at 66.2 A. It is important to choose an IndraDrive with electrical/thermal headroom and consider the 40-minute thermal constant for overload patterns.

How does the electrically released 70 Nm holding brake function on MSK100B-0200-NN-S1-AP2-NNNN?

It’s a spring-applied power-off safety brake that engages without power, releases at 24 V DC for providing 70 Nm static torque for holding vertical axes or maintaining position on E-stop.

What shaft and bearing load constraints apply when coupling this motor?

The MSK100 frame with keyway shaft must respect bearing loads. It supports 500 N max axial and provides radial-load curves versus overhang distance.

How do IP rating and ambient limits affect installation of MSK100B-0200-NN-S1-AP2-NNNN?

The motor is IP65 with an operational ambient of 0…40 °C, while sealing and cable glands must maintain this rating. For higher heat or washdown, apply shrouds/blowers and check derating tables before continuous-duty operation.
