ABB BSM80N-333AX BSM N-series AC brushless servo motors

The ABB BSM80N-0333AX is an ultra-compact servo motor in ABB's BSM N series, designed for ultra-high-speed, low-torque applications. It's the speed-extreme model in the series, suitable for specific applications requiring extremely high rotational speeds but with very light loads and stringent size requirements.

The coding convention for this model is consistent with other motors in the series, but the numbers reveal that it's a smaller, more high-speed focused motor:

• BSM: Brushless Servo Motor.

• 80: Frame size. This is the most significant feature of this model, indicating that the motor's flange size is approximately 80mm. This is smaller than the BSM90N and BSM100N, making it the most compact, lower-power, and lower-torque model in the entire BSM N series.

• N: N series, ABB's high-performance servo motor product line.

• 0333: Motor winding code. This code is crucial. "0333" typically indicates an extremely high-speed, low-torque winding configuration for this frame size. Its rated speed is significantly higher than the previously discussed "1250" or "3250" windings.

• A: Feedback System. A represents a standard incremental encoder.

• X: Shaft Option. X indicates that the motor output shaft is a smooth shaft with a flat key.

Key Features and Typical Applications

• Ultra-compact Design: Its 80mm frame size makes it the smallest model in the N series, ideal for applications with extremely tight space and weight requirements.

• Extremely High Speed: The "0333" winding indicates that this motor is optimized for very high speeds, while its continuous and peak torques are relatively low.

• Low Inertia: Due to its miniaturized rotor design, it has very low rotational inertia, meaning it can achieve extremely fast acceleration and deceleration with excellent dynamic response.

• Requires Compatible Drivers: Must be used with compatible ABB servo drives (such as the MicroFlex e190 series).

Typical Applications:

Due to its small size and high-speed characteristics, it is commonly used in:

• End effector (gripper) joints for small robots

• Precision optical positioning platforms

• Small PCB drilling/separation equipment

• Galvanometer drives for high-speed laser cutting/marking machines

• Medical and laboratory instruments (e.g., high-speed centrifuges, fluid pumps)

• Semiconductor wafer processing equipment
