Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.
Welcome to Oriental Motor's "Engineering Notes" Blog:

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.
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.
Historically, worm gears have been known as the most common type of gears used in a right angle gearhead. Their low cost and robust construction have been sufficient for general purpose applications. However, they are inefficient at slower speeds (higher reduction ratios), produce a lot of heat, take up a lot of space, and require maintenance. As efficiency standards became increasingly important globally, another type of gear is being adopted for right angle gearheads.
In the market of electric motors, there are products designed for general purpose applications, and there are motors designed for specialized applications, such as automated guided vehicles (AGVs) or autonomous mobile robots (AMRs). While standard, general purpose motors work for most applications such as factory automation, sometimes, it may help shorten your design cycle by going with a motor system that already offers the features that you are planning to implement into your design. In this post, we will summarize some of these features.
Parallel shaft gear motors are the standard configuration in the industry. However, right angle gear motors are gaining popularity for its ability to minimize the footprint of a machine, such as a conveyor. Another factor that should be considered is the type of gears used in the gearhead. While worm gear technology is popular, its gear efficiency can vary from 50~90% depending on gear ratio. On the other hand, hypoid gear technology keeps its efficiency at 80~95% regardless of gear ratio. Higher gear efficiency allows more torque to be transferred from the motor to the load shaft, and sometimes allows even smaller motors to be used.
