ABB BSM63N-150AX BSM N-series AC brushless servo motors

The BSM63N-150AX is a compact servo motor from ABB's N-series. It shares the same robust frame and high-quality features as the 275AX model but is designed for applications requiring lower torque and current.

Decoding the Model Number

• BSM: Brushless Servo Motor

• 63: Frame Size (63mm diameter)

• N: N-series

• 150: Motor-specific code indicating a shorter stack length and lower torque output compared to the 275 model.

• A: Design variant (winding type).

• X: Typically indicates a keyway on the shaft and IP65 sealing.

Key Technical Specifications (Typical)

• Frame Size: 63 mm

• Shaft: Likely a 14 mm diameter shaft with a keyway.

• Feedback Device: High-resolution encoder (e.g., 20-bit or 24-bit multi-turn sin/cos).

• Protection Class: IP65 (Dust-tight and protected against water jets).

• Cooling Method: Natural convection (self-cooled, IC410).

Performance Data (Must be verified with the official datasheet)

The "150" code signifies a lower power rating than the "275". Here are the expected values:

• Peak Torque (M₀): Likely in the range of 2.5 - 3.2 Nm

• Rated Torque (Mₙ): Likely in the range of 1.0 - 1.4 Nm

• Peak Current (I₀): Typically around 5 - 7 A

• Rated Current (Iₙ): Typically around 2.0 - 3.0 A

• Rated Speed: 3000 rpm

• Maximum Speed: 5000 - 6000 rpm
