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 combining the best of both open-loop and closed-loop technology.  First introduced in 1998 as the AS Series, the AlphaStep Hybrid Control technology ushered in a new age of stepper motors that can emulate servo performance at a lower cost.  Over the years, we have improved the AlphaStep Hybrid Control technology with 2 major advancements to close the gap between stepper motors and servo motors 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.

An AC motor can be simple to use, but its speed changes according to the size of the load or amount of voltage supplied.  For an application where keeping a uniform speed is important, there is another type of motor that can improve performance.

The BLH Series compact BLDC motors and drivers have been around for a long time, and there is a good reason.  Customers seem to favor the combination of a highly efficient, compact motor and a light weight board type driver that is easy to use.  Having a high torque, flat style hollow shaft gearhead as an option also helps in increasing torque as well as minimizing footprint.

What motors do you use for pumps?  For variable speed pump applications that typically use 3-phase AC induction motors with variable frequency drives (VFDs), there is another type of motor that can transfer fluids more consistently and help reduce footprint.
