Linear stages integrate servo motors

Linear positioning stages with built in integrated servo motors have been introduced by Bayside Motion Group. Called the Micro Plus (D) stages, they are designed to decrease overall system size while providing increased dynamic performance.

The integrated brushless DC servo motor and encoder design ensures a compact system. The magnetic rotor assembly is configured directly on the ball screw, and a rotary encoder senses position directly from the screw shaft. This design is said to eliminate mechanical errors and pliant parts, such as motor mounting brackets and flexible couplings.

Integrating the motor directly into the stage increases the system’s dynamic response and stiffness, while providing greater reliability.
