2AD160B-B35OA1-BS03-B2N2

Product Description:

The 2AD160B-B35OA1-BS03-B2N2 is a main spindle motor from Bosch Rexroth’s 2AD 3-Phase Induction Motors series. It comes with a frame size of 160 and a solid rated torque of 140 Nm, built for applications where the drive force has to stay strong across longer runs. The motor runs on 38.3 A of current, not the lightest pull but right for the kind of work it’s meant for. Feedback runs through a resolver system, which keeps the positioning clean and responsive in closed-loop operations. The motor housing sits under IP65 protection, so it blocks all dust and doesn’t mind a water spray.

The cooling setup uses an axial blower (B2N2 type), powered by 230V AC, pushing air across the body and keeping temps under control during long shifts. It doesn’t need extra ducting or chillers—just standard mounting and it handles the job. The build includes a B35 mounting code which lets it work in both foot and flange setups, more flexible than motors stuck with one or the other. The rated voltage is 400 V, so it pairs up well with common industrial drive systems. Not every unit handles this kind of torque at just 1500 rpm without noise or flutter, but this one stays pretty balanced.

Power comes in at 22 kW nominal, which puts it in the mid-high range for heavy motion tasks—machining spindles, gantry drives, or cutting heads that need torque stability over raw speed. The motor length is labeled B and lines up with the 160 frame to give the right mass and inertia profile for tighter control. The winding code BS03 rounds out the design with a configuration that supports solid startup pull and load holding. No extras are stuffed inside—just a clean industrial build that handles stress without dragging down the system. It's built to do hard work, not sit pretty.
