Product Description:

The ADS112C-B05TB1-ASF3-A2K4 is a servo motor produced by Bosch Rexroth Indramat in the ADS Servo Motors series. It converts electrical power from a compatible drive into precise shaft motion for positioning, milling, or packaging axes in automated machinery. The motor uses a C-length housing that accommodates the stator stack, and it includes a standard Indramat encoder for closed-loop speed and position feedback. This arrangement supports controlled acceleration, stable running speed, and repeatable motion in automated equipment.

During continuous operation, the motor supplies 20 kW of mechanical power while carrying a phase load of 58 A from a three-phase 380 V supply. This operating point produces 4.0 kW of loss heat that must be removed through the integrated cooling passages. At a base speed of 3000 rpm, the shaft delivers a stable 64 Nm against process loads. The AS winding pattern distributes current through the copper to support steady thermal performance at this duty point. A minimum cable cross-section of 16 mm² is required so resistive losses do not reduce terminal voltage or interfere with balanced current flow between phases. These electrical values indicate the drive capacity needed for accurate torque and speed control.

Liquid cooling maintains temperature stability, and at least 5.4 l/min must circulate through the jacket during operation. The cooling circuit can be pressurized to 3 bar without exceeding the housing limit, and a separate 1.5 bar sealing-air feed helps prevent dust or coolant from entering the bearing cavity. Rotor inertia of 0.02967 kg·m² affects acceleration response and helps moderate torsional oscillations in coupled loads. Structural vibration is limited to a maximum of 1.8 mm/s, which helps reduce stress on mounts and nearby sensors. The liquid-cooling jacket and sealing-air arrangement help the motor operate in enclosed machine spaces where heat and contamination must be controlled.
