The Bosch Rexroth synchronous servomotor R911333911 (MSK100A-0300-NN-M2-AG0-RNNN) is designed for industrial applications requiring precise torque and speed control. This model features a maximum rotational speed of 5200 rpm and operates within a temperature range of 0 to 40 °C at altitudes up to 1000 meters. The continuous torque at standstill is 17.0 Nm (100 K), with a maximum torque of 54.0 Nm. It draws a continuous current of 11.6 A at standstill, with a peak current of 45.9 A. The motor incorporates natural convection cooling, an A-side power connector, and an optical multiturn absolute EnDat2.1 encoder with 2048 signal periods. The shaft employs a sealing ring for lubricant protection, and the exterior has a black coating to resist corrosion. Additional features include a plain shaft, increased concentricity design, and a thermal time constant of 39 minutes. The motor has no holding brake and weighs 23 kg. Only qualified personnel should undertake installation and operation.

Frequently Asked Questions

What is the advantage of the plain-shaft + increased concentricity construction on MSK100A-0300-NN-M2-AG0-RNNN for couplings and gearheads?

The cylindric shaft and concentricity-optimized rotor/hub reduce runout and misalignment forces for improving coupling life and minimizing vibration at speed. It yields cleaner velocity feedback and tighter backlash performance when paired with precision gearheads or zero-backlash couplings.

How do the 11,200 mH winding inductance and 45.9 A max current shape drive tuning on MSK100A-0300-NN-M2-AG0-RNNN?

The high inductance damps di/dt for filtering PWM ripple and easing current-loop tuning, while the drive still has headroom for dynamic torque steps. Its 45.9 A peak enables short, decisive accelerations without saturating the magnetic circuit.

How is the A-side power connector and EnDat feedback on MSK100A-0300-NN-M2-AG0-RNNN integrated with Rexroth IndraDrive?

The IndraDrive firmware includes motor/encoder datasets for enabling rapid commissioning and electronic nameplate loading. Its electrical/connectivity conventions (A-side power, EnDat feedback) align with IndraDrive wiring kits for deterministic current/position loops.

Does MSK100A-0300-NN-M2-AG0-RNNN meet IP65, and what conditions apply?

The MSK series motors are typically designed to IP65 per EN 60034-5, while exact rating depends on specific options (e.g., shaft seal, connectors) and installation.

How do the 17.0 Nm (100 K) continuous torque and 54.0 Nm max torque of MSK100A-0300-NN-M2-AG0-RNNN translate to real duty cycles?

Its continuous torque is thermally bounded, while natural convection favors intermittent peak bursts within thermal time constants. It is important for cyclic profiles to calculate RMS torque/current and compare against 11.6 A continuous and 45.9 A peak allowances with adequate margin.
