Incremental Encoder Signals
Incremental encoders are used on motors and equipment as feedback devices to determine position and direction of machinery. Motor controllers can also use position information from the encoder to commutate the motor and calculate velocity for speed control. The incremental encoder is a critical … [Read more...]
Lead Screws 101 – A Basic Guide to Implementing a Lead Screw Assembly for Any Design
In many devices lead screw assemblies are used to convert motion from rotary to linear and vice versa. Historically these assemblies have had poor efficiencies and relied on grease for improved performance. Over the past few decades the advent of engineered polymers and new manufacturing … [Read more...]
Reimagining Reflective Encoders
Traditionally, reflective encoders have been considered a lower end option used when cost was more important than options. Whether needing high CPR, an index channel or compact sizes, it's time to reevaluate reflective technology. New encoders are still economical but now offer improved performance … [Read more...]

Comparing Slotted vs. Slotless Brushless DC Motors
Slotless brushless DC motors represent a unique and compelling subset of motors within the larger category of brushless DC motors. They are called “slotless” be-cause typical slotted brushless DC motors contain a stator core of laminated steel composed of slots separated by teeth around which copper … [Read more...]
Connecting Brushless DC Motors –the Phase Relationship
Brushless DC motor phase and sensor leads must be connected in a precise phase configuration for proper operation. Often the proper connection information is unavailable or explained differently from multiple suppliers. This paper explains the importance of the phasing relationship between motor … [Read more...]
