Product Description:

The ADS112B-B05TB1-ASF5-G2S4 is a liquid-cooled servo motor produced by Bosch Rexroth Indramat within the ADS Servo Motors series. As a rotary actuator, it converts electrical energy into controlled torque and speed for positioning tasks in industrial automation lines, where precise and repeatable motion is required by handling modules, gantries, or high-speed tooling. The motor integrates a coolant circuit to maintain thermal stability during continuous duty operation. It is intended for systems that need accurate starts, stops, and speed changes during repeated production cycles. This cooling method helps the unit support demanding motion cycles without relying on external airflow around the housing.

Under nominal operating conditions, the unit develops a continuous output of 20 kW while delivering 64 Nm of shaft torque at 3000 rpm. This performance is achieved from a three-phase supply of 380 V, with a phase current of 58 A. The rated power loss is 4.0 kW, so the cooling loop and surrounding machine space must both remove heat during operation. Installation requires a minimum cable cross-section of 16 mm² to keep conductor heating within an acceptable range. Pressure drop across the integrated cooling jacket stays at 0.2 bar at the nominal flow rate, which helps limit load on the circulation pump.

In the thermal circuit, a coolant temperature rise of 10 K is permitted between the inlet and outlet when the flow rate is at least 5.4 l/min. The internal coolant volume is 0.7 l, and the circuit should be filled with a treated water-glycol mixture filtered through elements rated at ≤100 µm. The loop may operate at pressures up to 3 bar without exceeding the housing limit. Clean coolant and stable flow help the jacket transfer heat away from the windings and support steady output over long operating periods.
