Product Description:

The ADS112C-B05TB1-ASF3-A2S4 is an industrial AC servo motor from Bosch Rexroth Indramat’s ADS Servo Motors series. This liquid-cooled unit converts electrical energy into controlled mechanical torque for positioning axes and spindle drives in automated machinery. By integrating stator windings optimized for high current density, the motor delivers repeatable motion profiles while fitting into compact machine frames. The manufacturer supplies the motor as a ready-to-mount component for closed-loop drive systems that demand precise speed regulation under continuous duty.

Electrical performance centers on network compatibility and continuous output. The motor operates on a line voltage of 380 V, drawing a rated phase current of 58 A through power leads that must be at least 16 mm² in cross section to limit conductor heating. Under these conditions it produces 20 kW of mechanical power with a thermal dissipation of 4.0 kW that must be removed by the cooling circuit. Nominal mechanical speed is 3000 min⁻¹, and the electromagnetic design yields 64 Nm of torque across the entire speed range without field weakening. For stability in dynamic applications, permissible housing vibration is limited to 1.8 mm/s, preventing encoder errors and bearing damage.

The motor’s enclosure carries a IP54 protection rating, so internal components are shielded against limited dust ingress and water spray. Liquid cooling keeps stator temperatures predictable; with a coolant volume of 0.7 L circulating through the jacket, a temperature rise of only 10 K is expected when the flow remains above 5.4 L/min. The hydraulic layout tolerates system pressures up to 3 bar and shows a pressure drop of 0.2 bar at nominal flow, allowing compact pump selection. Dynamic response is aided by a rotor inertia of 0.02967 kg·m², supporting quick acceleration while still smoothing load fluctuations.
