BLDC Servo Motors for Collaborative Robots

Content image

Lin Engineering designs, engineers, and manufactures a variety of BLDC motors for collaborative robot applications. Cobot arms typically consist of compact multi-axis assemblies with unique requirements per axis, often requiring precise speed and position control, as well as the ability to hold position under varying loads. Lin Engineering offers cost-effective motor solutions for all axis of motion. 

Frameless BLDC Motors

Frameless BLDC motors offer maximum engineering flexibility and excellent torque-to-size ratio. The rotor and stator are delivered as separate components that can be mounted directly to the assembly in which the motor is used.
