The Perfect Pair: Couplings

Coupling: the pairing of two items.  Couplings are a product that is designed to connect shafts that are manufactured separately such as motor and connecting mechanism. The main purpose is to transfer rotary motion or torque from one shaft to ...

Mastering Ball Screws Pt 3: Ball Screw Operating Performances

Friction is one factor in ball screw performance.  There are 2 different friction torques affecting screw operation performance.  Each friction torque is dependent on the type of feed screw. Feed screw is a mechanical element used to convert rotational motion ...

The great debate: Stepper or Servo?

Many engineers may stumble upon this question when specifying a motor for an application; should I use a Stepper or a Servo motor? Both stepper and servo motor are excellent but, what’s really important is understanding their capabilities.  The simplest way to ...
