Product Description:
Bosch designs the 3-phase induction motor 2AD160B-B35OA1-BS03 with a nominal speed of 1500 rev/min. It uses a high-resolution encoder feedback system that provides absolute accuracy with regard to zero point as ~0.02 degree and relative accuracy of ~0.01 arcminute. This motor works on a 305 V AC supply source to produce a continuous turn effect of 191 Nm.
The 2AD160B-B35OA1-BS03 induction motor features both flanges and feet mounting configuration of installation. Its power cable of 25 mm^2 requirement goes towards side A from the top located terminal box on the body. The motor attains cooling through an axial blower whose airflow passes through the enclosure, from side B-A. The blower operates by means of a separate independent 400/460 V AC input and it consumes 220 VA of power to provide 1120 m^3/h of air flow on average. The 2AD160B induction motor possess a speeding capability up to 6000 rev/min and its rotational moment of inertia is rated at 0.174 kgxm^2. The mass of the motor is 205 kg and its frame size is 160 mm. Its class F electrical insulation ensures safety and permits operation on sites with high thermal values. The 2AD160B induction motor has temperature constant of 60 minutes and its sound pressure level is 75 ~3dB(A).
The 2AD160B-B35OA1-BS03 induction motor comes with a built-in NTC thermistor inside the winding to monitor temperature and protect the motor from overheating by timely notifying the drive unit. The motor's IP65 rating safeguard the internal components from external pollutants greater than 1 mm and its operating temperature is 0 to 45 degrees C. This 2AD160B induction motor utilizes a rated power of 30 kW and 72 A current under normal load conditions.
