Linear motion using stepper-based linear actuators: Part 1: Linear Actuator styles
Stepper motor linear actuators are an optimal choice when converting rotary torque to linear force. The construction of these actuators allow
for new designs that are more compact and reliable by replacing conventional system mechanicals such as rack and pinion sets, belt and pulley systems and pneumatic air cylinders with electric motor actuators.
Today’s motion applications are requiring more precise control of both speed and position. The requirement for more complex move profiles is leading to a change from pneumatic and hydraulic controls to electric motors. However, even the simple electric motors used today may no longer provide adequate control.
Motion Control Shades of Grey: IP65 rating and what it means for your application
There are so many opinions about the meaning of IP ratings that it is, in a word, frustrating. The actual definitions are very black and white. Published by the International Electrotechnical Commission (IEC), and detailed by IEC standard 60529, IP ratings/Ingress Protection Ratings or International Protection markings classify and rate the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures.
