Product Description:

The ADS112C-B05TB1-ASF3-N2K5 is a liquid-cooled synchronous servo motor produced by Bosch Rexroth Indramat within the ADS Servo Motors series. It converts electrical energy into controlled rotary motion for positioning or continuous-duty axes in automated machinery. The motor is intended for servo systems that need precise speed regulation and repeatable position control under changing loads. By routing coolant through an internal jacket, the unit maintains stable thermal conditions so that high dynamic torque can be delivered without overheating during demanding industrial cycles.

At the electrical interface, the motor is rated for 380 V line-to-line and draws 58 A to produce a continuous shaft torque of 64 Nm at a base speed of 3000 rpm. This operating point yields 20 kW of mechanical output while removing 4.0 kW of heat through the coolant channel. The voltage and current are used for inverter sizing, while the torque, speed, and power figures show the motor's continuous operating point for conveyors, presses, or milling spindles. Continuous liquid cooling reduces temperature swing in the stator during long production runs. Power conductors must have a minimum cross-section of 16 mm² so cable heating stays controlled during sustained duty.

The cooling circuit holds 0.7 L of fluid and must receive at least 5.4 L/min filtered to 100 µm, limiting the temperature rise to 10 K with only 0.2 bar pressure drop while accommodating system pressures up to 3 bar. The low pressure drop helps the cooling loop operate with modest pump demand in centralized thermal circuits. Filtered coolant helps keep the internal cooling passage clear during continuous operation. Sealing air may be applied at 1.5 bar to protect the bearing cavities from process dust and vapor intrusion. Dynamically, a rotor inertia of 0.02 kg·m² enables rapid acceleration without excessive drive currents, and overall machine integrity is supported by a maximum vibration velocity of 1.8 mm/s, allowing direct installation on precision frames without auxiliary dampers.
