Simplifying BLDC Commutation and Feedback System

Reduce motor package complexity and cost with modular solutions. In a Brushless DC (BLDC) motor system, an electronic mechanism is required to commutate the system. Unlike a Brush DC motor system, the permanent magnet is located at the rotor and the windings are located at the stator. As a result, windings are required to energize in sequence, to enable smooth commutation. When using hall sensor solutions, the manufacturer needs to add a printed circuit board and magnet that will increase cost. Complexity and costs can by reduced by using a 6-channel optical encoder, where the positional encoder and commutation feedback are combined into one module.

Miniature Reflective Encoders - Affordable Sensors for the Portable Medical Device Market

Reflective encoders have become a popular choice among portable medical device manufacturers that must offer products with greater precision, lower power consumption, lower weight and smaller size at a competitive cost in the health care device market. These enhanced motion control feedback devices have better performance than existing magnetic technology based encoder devices without increasing cost or power dissipation. This white paper helps you understand the benefits of these devices.
