Product Description:
The induction motor 2AD160B-B05OR2-BS03-A2N1 is designed by Bosch with a stringent frame of 160 mm size. It offers flange mounting configuration and possess R level of vibration severity with a limit of 1.8 mm/s at 600-1800 RPM and 4.5 mm/s at a rotational speed of 6000- 8000 RPM. At 1 meter distance this motor produces an acoustic level of 75 dB(A) with 3 dB(A) tolerance.
The 2AD160B-B05OR2-BS03-A2N1 induction motor operates on a 305 V AC power supply and consumes a nominal power of 30 kW to deliver a torque of 191 Nm. At standard conditions, the motor turns at 1500 RPM rotating speed while it can achieve a maximum speed of up to 6000 RPM. It is rated for a nominal current of 72 A and requires a 25 mm^2 of cross-sectional wire for connection to the top mounted terminal box for operating effectively. The 2AD160B induction motor comes with a side A to B suction mode axial air blower that consumes 220 VA of power from a 3-phase AC 400/460 V source at 50/60 Hz to maintain air circulation of 1120 m^3/h for thermo-regulation at high speeds. The motor also has a time constant rated at sixty minutes to stabilize in temperature by itself.
The 2AD160B-B05OR2-BS03-A2N1 induction motor features a resolution feedback system that allows detecting absolute positions without data loss with a relative and absolute accuracy of 0.01 degree and 0.02' respectively. The 2AD160B induction motor is presented with a seal less plain shaft that does not support any extension or assembly attachment at the B side for encoder mounting. Its moment of angular inertia is 0.174 kgxm^2 and this brakeless motor weighs approx. 205 kg on its own.
Frequently Asked Questions about 2AD160B-B05OR2-BS03-A2N1:
Q: How does the axial air blower support high-speed operation in the 2AD160B-B05OR2-BS03-A2N1 motor?
A: The axial blower maintains 1120 m^3/h airflow, effectively dissipating heat during high-speed operation, ensuring thermal stability and motor longevity.
Q: Why is a seal-less plain shaft used in the 2AD160B-B05OR2-BS03-A2N1 induction motor?
A: It reduces potential failure points and is ideal for applications that do not require B-side encoder mounting, simplifying mechanical integration.
Q: What benefit does the 0.174 kgxm^2 rotor inertia provide in the 2AD160B-B05OR2-BS03-A2N1 motor?
A: This inertia supports smooth load transitions and improved motion stability in high-precision applications, especially where acceleration needs to be controlled.
Q: What role does the resolution feedback system play in the 2AD160B-B05OR2-BS03-A2N1 motor?
A: It provides both absolute and relative positioning, which enhances control accuracy and eliminates cumulative error during multi-axis coordination.
Q: Why does the 2AD160B-B05OR2-BS03-A2N1 use a 25 mm^2 wire connection?
A: The large cross-sectional area reduces electrical resistance and supports high current flow, minimizing voltage drop during full-load operations.
