Product Description:
The MS2S05-B0BTN-IMHG1-NNDNN-NN is a synchronous servomotor built by Bosch Rexroth Indramat for the MS2S Synchronous Servomotors series. As a low-inertia rotary actuator, it provides position and velocity control for packaging, assembly, and handling axes. The motor conforms to the IM B5 / IM 3001 mounting pattern and has a 98 mm square flange. It also integrates a Size 1 spring-applied holding brake that is electrically released and secures the shaft at standstill when power is removed.
Its nominal speed reaches 6000 rpm, and the self-cooling housing dissipates heat without external airflow. Code BT identifies the installed winding set. The holding brake operates from a 24 V DC (±10%) brake supply, while the power electronics sense rotor position through a magnetic multi-turn encoder with an 18-bit single-turn resolution at the Basic performance level. The encoder electronics operate from 8 to 12 V, draw 130 mA, and communicate through the ctrlX SENSEmotor interface over a single rotatable M17 cable secured by a Quick-Lock SpeedTec collar. Standard deep-groove ball bearings guide the shaft, while alignment errors remain within 0.04 mm for concentricity and 0.08 mm for coaxiality. The centering hole complies with DIN 332 Part 2, uses a DS M6 thread, and seats against a flange manufactured to tolerance class N.
The spring-applied brake provides 7.20 Nm of holding torque and may be actuated 20 times per hour. It tolerates 500 emergency stops from 3000 rpm, with a maximum energy dissipation of 500 J per stop. The enclosure is sealed to IP65, and a standard RAL 9005 black coating protects the exterior from contamination. Mechanical output is transferred through a smooth shaft with a diameter of 19 mm and a shaft sealing ring. A 95 mm centering collar positions the motor against a 115 mm hole circle with 9 mm mounting bores. The compact housing uses frame size 05 and frame length B, while the low-inertia rotor supports rapid acceleration. The multi-turn encoder distinguishes 65,536 revolutions and maintains a system accuracy of ±360 arcseconds for high-speed positioning tasks.
