Title:
多軸リニアモータアクチュエータ
Document Type and Number:
Japanese Patent JP7437027
Kind Code:
B2
Abstract:
A multi-axis linear motor actuator has a circuit board having a size covering coil portions in linear shaft motors arranged in a row, and combined with the linear shaft motors to be adjacent thereto and parallel to its arrangement direction; and magnetic shielding plates, longer than the coil portions, arranged and fixed along an axial direction at positions corresponding to positions between adjacent coil portions. Hall sensors are installed in the circuit board in each region corresponding to each linear shaft motor at intervals in a moving direction of a shaft of each linear shaft motor. Each magnetic shielding plate has a wide portion with a width greater than a diameter of the coil portion at a part corresponding to the region where the Hall sensors are installed. The circuit board has first slits for inserting the wide portions. The Hall sensors are installed adjacent to the wide portion.
