Welcome to Oriental Motor's "Engineering Notes" Blog:

Other than torque or speed, another factor should be considered when sizing motors.  

Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed.  For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

The terms "absolute" and "incremental" come up frequently in the world of position control.  The exact meaning can be the type of motion done by the motor in programming terms or the type of feedback device used with the motor.  In this article, we will focus on the differences between an incremental closed-loop feedback system and an absolute closed-loop feedback system.

The word, "AlphaStep", describes Oriental Motor's patented Hybrid Control technology, which offers improved stepper motor performance by sensing the rotor position and automatically switching between open-loop and closed-loop operation when necessary.  This post explains the unique technologies offered within the AlphaStep family of products and summarizes the numerous integrated options available.  It also can serve as a website navigation guide (video added).

Along with the advancement of industrial technology, maintenance methods of motion control components of a machine, such as motors, drives, and sensors, have also evolved.  Which method is the most efficient?

The most common method of maintaining a machine after a failure has occurred was the traditionalreactive maintenancemethod.  Realizing the need for improvement, maintenance personnel started to estimate life and replace motion control components before they fail.  This is called the preventive maintenancemethod.  More recently, with the advancement of IIoT (Industrial Internet of Things) and real-time availability of status data, another method was born - the predictive maintenance method.

The three maintenance methods have the same goal of eliminating machine downtime but do it differently.

Robot adoption is increasing in many industries due to global efforts in reducing long term costs, maintaining quality, and freeing up time for humans to do "human" tasks.  For example, by using a robot to clean floors or restock shelves in a supermarket, human employees can spend more time helping or selling to their customers.  A company can either tap into this robotic trend by buying ready-made robots, or by making their own with less cost. 

If engineering resources are limited, selecting the right components can reduce the difficulty and time for building a robot.

There are many mechanisms that convert rotary motion of an electric motor to linear motion, such as belt/chain drives, screw drives, rack & pinion drives and even CAM drives.  Each mechanism offers advantages and disadvantages. Choosing the right technology can help increase load, speed, travel distance, or positioning accuracy.

The MEXE02 support software is a universal motion control and monitor software used with multiple products from Oriental Motor, such as the AZ Series, RK2 Series, BLE2 Series, and BX2 Series.  This article is useful for first-time users to gain a quick understanding of the software and what it can do.

With recent trends focusing on improving engineering efficiency, many products have been developed to specifically help shorten design cycles for machine automation.  Part of improving efficiency is making products easier to use, so additional time and resources can be spent elsewhere.  This post describes a product feature that can make index table applications less complex to manage.

Automation is great for repetitive tasks, such as test fixtures for a process that has to repeated.  In this post, we will explain how to perform a reciprocating motion (back and forth cycles) with a product that does not require a PLC or external presence sensors, which can help speed up design cycles.
