ABB BSM90N-3250AX BSM N-series AC brushless servo motors

The ABB BSM90N-3250AX is a compact, well-balanced servo motor. Its main features are its small 90mm frame size and the "3250" winding, which provides a balance between speed and torque.

Item Information

Product Name: ABB BSM N Series AC Brushless Servo Motor

Product Model: BSM90N-3250AX

Manufacturer: ABB

Motor Type: AC Permanent Magnet Synchronous Servo Motor

Model Analysis

According to ABB's naming conventions, we can break down this model number:

BSM: Brushless Servo Motor.

90: Frame size. This is a key feature of this model, indicating that the motor's flange size is approximately 90mm. This is smaller than the BSM100N (100mm flange), generally meaning smaller size, lighter weight, and lower rated power/torque.

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

3250: Performance code for the motor windings. This number defines the motor's unique speed-torque characteristics. "3250" represents a performance level between the previously mentioned "2150" (higher speed) and "4150" (higher torque), offering a balanced compromise.

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

X: Axis Option. X indicates the motor output shaft is an optical shaft with a flat key.

Key Features and Typical Applications

Compact Design: With a 90-frame mount, it is smaller than a 100-frame motor, making it ideal for space-constrained applications.

High Performance: Features the high precision and high response speed of a servo motor.

High Reliability: Employs permanent magnet synchronous technology, suitable for harsh industrial environments.

Requires Matching Driver: Must be used with a matched ABB servo driver (such as the MicroFlex e190 series).

Typical Applications:

Due to its small size and balanced performance, it is commonly found in:

Small industrial robots (such as joints in SCARA robots)

Precision assembly equipment

Semiconductor and electronics manufacturing equipment

Small packaging machines

Medical devices

Laboratory automation
