This made it natural for OJ Electronics to look at stepper options when we decided to develop a whole new type of motor for rotary heat exchangers.<\/p>\n<p>From modern printers to emerging CNC and robotics technologies, stepper motors are utilized for their step-by-step accuracy and high torque, enabling consistent torque delivery even under demanding conditions such as low-speed operation. This ability to maintain reliable performance under demanding conditions is what captivated our engineers.<\/p>\n<h2>Constant Torque at Low Speeds<\/h2>\n<p>Compared to many other applications, rotary heat exchangers need to deliver consistent performance at lower speeds. This requires high torque at even very low speeds. In theory, OJ\u2019s engineers reasoned, a stepper motor would enable heat exchangers to operate at exactly the right speed and maintain their speed \u2013 even with humidity and other difficult conditions. And this would help ensure consistently high performance.<\/p>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-8720\" src=\"https:\/\/ojelectronics.com\/drives\/wp-content\/uploads\/sites\/26\/2024\/11\/stepper-motor-drhx.png\" alt=\"Stepper motor and drive for rotary heat exchangers from OJ Electronics\" width=\"600\" height=\"582\" srcset=\"https:\/\/ojelectronics.com\/drives\/wp-content\/uploads\/sites\/26\/2024\/11\/stepper-motor-drhx.png 836w, https:\/\/ojelectronics.com\/drives\/wp-content\/uploads\/sites\/26\/2024\/11\/stepper-motor-drhx-300x291.png 300w, https:\/\/ojelectronics.com\/drives\/wp-content\/uploads\/sites\/26\/2024\/11\/stepper-motor-drhx-768x745.png 768w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/>A Curious Hybrid \u2013 and Legendary Series<\/h2>\n<p>In practice, a stepper motor was only the first step in creating what would become OJ\u2019s rotary drive solution, launched in 2017. As development work progressed, our team implemented major modifications \u2013 such as going from the two-phase to three-phase power. The many modifications resulted in a final product so heavily customized, it can better be defined as a hybrid between a stepper and a permanent-magnet motor.<\/p>\n<p>&nbsp;<\/p>\n<h2>Simple Means Reliable<\/h2>\n<p>There was another reason why the stepper motor made an advantageous starting point for OJ\u2019s rotary drive solutions. The lack of gears, hardware sensors and other components found in geared motors make these motors simple and straightforward, which can mean a more reliable system with fewer parts to wear and require maintenance. And it makes installation faster and more straightforward.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"factbox\">\n<h3>Take a Deep Dive Into Our Solutions for Rotary Heat Exchangers<\/h3>\n<p>If you are looking to incorporate rotary heat exchangers into your solutions, be sure to consider our <a href=\"https:\/\/ojelectronics.com\/drives\/products\/drhx-analog-control\/\">OJ DRXH drives<\/a> and <a href=\"https:\/\/ojelectronics.com\/drives\/products\/drhx-analog-control\/\">MRHX motors<\/a>.
