The Bosch Rexroth IndraDyn S synchronous servomotor, MPN R911341047 (MSK040B-0450-NN-M3-UP1-NNNN), features a 40 frame size with length B and weighs 3.1 kg. It operates with a four-pole configuration and utilizes a capacitive multiturn absolute encoder with Hiperface interface, rotatable by 240°, providing 16 signal periods resolution. Key electrical parameters include 14.70 Ohm winding resistance, 1.26 Nm/A torque constant at 20°C, and 77.8 V/1000 rpm voltage constant. The motor achieves up to 6000 rpm, a maximum torque of 5.1 Nm, and a continuous torque at standstill of 1.9 Nm (100 K), with continuous and maximum currents of 1.7 A and 6.0 A, respectively. Its holding brake is electrically released with a 4 Nm torque. Shaft configuration includes a keyway and sealing ring per DIN 6885-1. Winding inductivity is 64,700 mH. The design provides natural convection cooling, a 13-minute thermal time constant, and a moment of inertia of 0.00010 kgm². The motor operates safely between 0 and 40°C, carries an IP65 protection rating, complies with insulation class 155, and generates less than 75 dB sound pressure.
