Product Description:

The ADS112B-B05TB1-ASF5-A2S4 is a liquid-cooled servo motor manufactured by Bosch Rexroth Indramat within the ADS Servo Motors series. It supplies precise rotary motion for industrial automation axes that demand sustained medium-speed output and fast dynamic response. The unit converts a three-phase electrical supply into controlled mechanical torque, allowing positioning or speed loops to be closed by the drive controller while the integrated 1 Vpp encoder returns high-resolution rotor position.

At its rated operating point the motor reaches 3000 rpm and produces a continuous shaft torque of 64 Nm. This corresponds to a mechanical output of 20 kW. To achieve this, the stator windings draw a phase current of 58 A from a nominal line of 380 V. Heat generated by copper and iron losses is listed as a rated power loss of 4.0 kW and is removed by an external coolant circuit. The internal channels cause only 0.2 bar of pressure drop, so standard pump modules can be used. The housing carries an IP54 protection class that guards against limited dust ingress and water spray, allowing installation on machine frames without additional enclosures. An NTC/Bimetal sensor monitors winding temperature and signals the drive when thermal limits approach.

To maintain dielectric integrity, the sealing air circuit may be pressurized up to 1.5 bar. The coolant loop must supply at least 5.4 l/min to hold the windings near design temperature even at the maximum system pressure of 3 bar. Power terminals accept conductors no smaller than 16 mm², a cross-section chosen to limit resistive losses at the specified current. The motor end windings tolerate vibration levels of 1.8 mm/s, and the sine-cosine encoder supports high-bandwidth servo control when paired with compatible Rexroth drives.
