Product Description:

The MS2S04-B0BTN-IMHG1-NNDNN-NN servo motor is manufactured by Bosch Rexroth Indramat for the MS2S Synchronous Servomotors series. It converts electrical power into controlled rotational motion for precise positioning and repeatable velocity profiles. The motor is suitable for compact automated assembly stations, packaging modules, and material-handling axes that require responsive motion control.

With a nominal speed of 6000 rpm, the motor supports high throughput on compact mechanisms. A size 1, electrically released spring-force brake delivers 3.50 Nm of holding torque and operates according to the closed-circuit principle for fail-safe stopping. The brake permits 20 actuations per hour and withstands 500 emergency stops, with each stop dissipating 200 J. The smooth 14 mm shaft has a shaft sealing ring that helps prevent contaminants from reaching the bearing area. It aligns with a 50 mm centering collar and fits a 95 mm hole circle with 6.6 mm mounting openings; concentricity and coaxiality remain within 0.035 mm and 0.08 mm, respectively. The B-length frame has an 82 mm flange with standard tolerance N and mounts in the IM B5 / IM 3001 orientation. A deep-groove ball bearing supports the low-inertia rotor. Heat is removed by self-cooling, and the housing meets IP65 requirements for protection against dust and water jets. Power and signal lines connect to winding code BT through a single rotatable M17 connector with a quick-lock SpeedTec latch, and the motor accepts a 24 V DC supply with a tolerance of ±10%.

The motor uses a magnetic multi-turn encoder with an 18-bit single-turn resolution. It distinguishes up to 65,536 revolutions, providing absolute feedback through the ctrlX SENSEmotor interface. The encoder electronics draw 130 mA from an 8–12 V rail and maintain a system accuracy of ±360 arcseconds. The Basic performance classification supports tight control-loop gains on high-speed axes. A DIN 332 Part 2 centering hole with a DS M5 thread assists with mechanical alignment during installation. Black RAL 9005 varnish protects the housing surface against routine industrial exposure.
