Product Description:
Bosch Rexroth is the manufacturer of the 2AD160B-B35RA1-BS03-A2N1 induction motor of the 2AD series which serve as main spindle drives and servo drives with high performance capabilities in machine tools. It delivers continuous 30 kW of heavy-duty rated mechanical output power. The motor is used in applications where production efficiency depends on constant rotational speed and torque.
The maximum rotational power of the 2AD160B-B35RA1-BS03-A2N1 induction motor is 4500 rpm. It is capable of driving heavy mechanical loads with a rated torque of 191 Nm. The motor is rated at 305 V which immobilize its steady operation under fluctuating loads. It has a nominal continuous current duty of 72 amps under regular continuous duty. The sum of the motor masses moment of inertia is 0.174 kgm² when acceleration and deceleration are equal. It has a feedback emulator that supports high-definition feedback to enhance positional control in automating systems. The 60 min thermal time constant allows duty cycles that can be stretched to their maximum. Its heat dissipating motor windings are cooled by an axial flow blower.
The 2AD160B-B35RA1-BS03-A2N1 induction motor connecting interface employs a junction box on side A to make electrical termination orderly. It is a motor encoder of 2500 increments of accurate speed and position feedback type. The bearings are of standard industrial design to ensure reliability and durability in service. Its cooling airflow rate is defined at 1120 m³/h to have optimal thermal performance.
The 2AD160B-B35RA1-BS03-A2N1 induction motor normal temperatures are 0 to 40°C. It is constructed using an insulation class F to be thermally resistant under continuous duty. The assembled weight of the motor is 205 kg. It is fully key balanced and has a shaft seal ring that enables smooth delivery of the torque to the output shaft.
