New Control Technique Combines Servo Performance With Step Motor Cost

by Chuck Lewin, Founder and CEO, Performance Motion Devices, Inc.

POSTED: 06/29/2020

When it comes to step motors, a new drive technique called stepper servo is making everything old new again and winning back machine designers who may have relegated step motors to the category of low cost but low performance. What makes this technique powerful is that it can use a generic

Measure While You Press — Force Feedback in Linear Actuators

POSTED: 04/20/2020

Introduction Successful automation processes that use linear actuators may benefit from incorporating force feedback into the control loop. In fact, most motion specialists are familiar with the concept of electrical feedback or pressure feedback from forces applied in electrical or hydraulic systems. Monitoring force feedback can improve process control, help maintain consistent

Benefits of Electric Linear Actuators Over Hydraulic Systems

POSTED: 04/20/2020

Contrary to common opinion electric actuators actually have a lower total cost than hydraulic cylinders. Although the upfront costs of an electric linear actuator can be more than a hydraulic system, the additional benefits described below tip the balance in favor of electric linear actuators. CONTROL Electric linear actuators equipped with a

Rotary Encoders Join the Industrial Internet of Things

by Jeff Smoot

POSTED: 02/26/2020

While it may be that Benjamin Franklin is widely attributed to making the phrase “time is money” popular, I do not believe that I am stretching the truth by stating that this phrase also rings painfully true for anyone associated with machine design, industrial automation, or robotics. Machine down time

The formula for the effective torque

POSTED: 01/24/2020

When selecting the most suitable motor for dynamic applications, the effective torque is a crucial quantity. In many applications, a motor’s continuous output is limited by its thermal budget. Optimum design is crucial to keep a motor from overheating in an application. The rated torque is usually used during design. However,

Solutions to Reduce Stepper Motor Resonance

by Zoe Li, Applications Engineer

POSTED: 09/20/2019

Every stepper motor has a resonance point, and sometimes motor vibration can affect motor performance and motor life. It is important to know the possible solutions to eliminate motor vibration. Stepper motors have discreet positions that the rotor can move to. Due to rotor inertia, when a stepper motor makes a
