The Role of Magnetic Grating Rulers in Linear Motors

A linear motor directly converts electrical energy into linear motion. It typically consists of a fixed stator and a movable mover, using changes in magnetic fields to generate linear movement. For precise position and motion control, linear motors often require high-precision sensors, among which magnetic grating rulers are very important.

Magnetic grating rulers are sensors that measure position using magnetic fields and can be used to measure the position and speed of linear motors. They usually consist of magnetic poles and detectors—the magnetic poles are mounted on the stator while the detector is mounted on the mover. As the mover moves along the track, the changing magnetic field is captured by the detector and converted into an electrical signal.

By analyzing these electrical signals, the magnetic grating ruler can determine the linear motor's position and feedback this information to the control system to achieve precise position control. Therefore, magnetic grating rulers are essential components in linear motors to ensure accurate trajectory and speed control.

In practice, magnetic grating rulers provide the following key functions in linear motors:

1. Accurate position measurement: critical for high-precision motion control applications such as semiconductor processing, lithography, and laser cutting—magnetic grating rulers can achieve micron-level accuracy.

2. High-speed motion control: they quickly capture mover position changes and transmit this information to the control system for high-speed control.

3. Reliability: as a non-contact sensor, magnetic grating rulers avoid friction and wear, improving reliability and reducing maintenance compared to mechanical sensors.

4. Flexibility: magnetic grating rulers can be customized for measurement range, resolution, and output signals to meet application requirements.
