Other than torque or speed, another factor should be considered when sizing motors.
Welcome to Oriental Motor's "Engineering Notes" Blog:
Products and technology are only valuable when coupled with skilled people and services to support them. ORIENTAL MOTOR U.S.A. CORP. has dedicated over 33 years to establishing a service and support system to better serve customers. It is our goal to provide the best product and service from the design phase, through the sale and beyond.
Our blog will feature:
- Introductions to New Products and Technology
- Application Examples, Improvements and Problem Solving
- Tips and Recommendations for Motor Selection, Installation and Use
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" comes up frequently in the world of position control. The exact meaning changes according to the context they are used in. For example, absolute and incremental motion can refer to the type of motion done by the motor either by relating it to the absolute home position or the last known position. Absolute and incremental feedback can also refer to the type of feedback device being used with the motor. In this blog post, we will focus on the feedback system and hopefully clarify some differences for you.
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. First introduced in 1998 as the AS Series, the ushered in a new age where stepper motors can emulate servo performance at a lower cost. Over the years, we improved the AlphaStep Hybrid Control technology with 2 major advancements to close the gap between stepper motors and servo motors even further.
This post explains the unique technologies offered within the AlphaStep family of products then summarizes the numerous integrated options available. It also serves as a website navigation guide.
Along with the advancement of industrial technology, the method of maintaining motion control components of a machine, such as motors, drives, and sensors, has also evolved. The most common method of maintaining a machine after a failure has occurred was the traditional method. Realizing the need for improvement, maintenance personnel started to estimate life and replace motion control components before they fail. More recently, with the advancement of IIoT (Industrial Internet of Things) and real-time availability of status data, another method was born. While the two newer methods have the same goal in eliminating machine downtime, only one does it efficiently.
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 the build.
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 many products from Oriental Motor, such as the stepper motor drivers from AZ Series, AR Series, and RK2 Series, or brushless DC motor drivers from BLE2 Series and BX2 Series. This post 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 an example of 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.
