I. Model Analysis (Key Differences)

2AD100B: Series 2AD, Frame 100, Core Length B

B05: Installation Type = Flange Installation (IMB5)

O: Power Terminal Position = Top (Top)

B: Power Outlet Direction = B Side

4: Cooling Method = Axial Fan 115V AC, Direction B→A (This is the biggest difference from the previous 2AD100B-B05OB1: B1 = 230V, B4 = 115V)

AS03: Feedback = High-Resolution Incremental Encoder, No Brake

A2N1: Shaft End / Sealing / Standard Configuration Combination

II. Core Parameters (Typical Values for the Same Specification 2AD100B)

Rated Power: Approximately 2.2–3.0 kW (3AC 400V)

Rated Torque: Approximately 14–19 Nm

Rated Speed: 1500 rpm

Maximum Speed: Up to 9000 rpm (Dependent on the Drive)

Working Voltage: 3AC 400V

Cooling Fan: 115V AC Axial Fan (B→A)

Protection Level: IP65

Insulation Level: F (155℃)

Operating Temperature: 0 ~ +40 ℃

Installation Type: Flange IMB5

Weight: Approximately 18–20 kg

Encoder: Incremental, High-Resolution, Compatible with IndraDrive

III. Main Differences from the Previous Models

2AD100B-B05OB1-AS03-B2N1: Fan 230V, Outlet B Side, Shaft End B2N1

2AD100B-B05OB4-AS03-A2N1: Fan 115V, Outlet B Side, Shaft End A2N1 (This is your current model)

In simple terms: Mechanical dimensions, power, and encoder are exactly the same. Only the fan voltage and shaft end configuration have been changed.

IV. Compatibility and Applications

Drives: Rexroth IndraDrive (HCS02, HMD01, etc.)

Cables: Power Shielded Wire + Incremental Encoder Wire

Applications: CNC Machine Spindle / Feed Axis, Printing and Packaging, Bending / Laser Cutting, Automated Production Line, etc. (Scenarios requiring 115V fan power supply)
