What’s inside a massage gun? How is a massage gun constructed? These are questions that often go unanswered, but that’s where we come in.<\/p>\n\n\n\n
Armed with knowledge gained from dismantling two massage guns and closely examining their inner workings, I’ve crafted what I believe to be useful information about what makes these trendy gadgets tick.<\/p>\n\n\n\n
Take a front-row seat with the experts and learn!<\/p>\n\n\n\n\n\n Massage guns work by using a motor to create rapid percussive movements, delivering targeted pressure to muscles for relief and relaxation.<\/p><\/blockquote><\/figure>\n\n\n\n Sounds pretty simple, right? Don\u2019t count your guessing stars yet, there\u2019s more to it. Let\u2019s unpack a few things. <\/p>\n\n\n\n So, these are the elements without which there is no massage gun. We will discuss each of them in more detail later, but for now:<\/p>\n\n\n\n Below, the inner of the Each component you see will be discussed in detail shortly.<\/p>\n\n\n\n This diagram illustrates the inner workings of a massage gun, specifically the Ekrin B37<\/a>, which we have tested<\/a> extensively.. It highlights each essential part, from the brushless motor to the high-density EVA head. All these components, plus the battery, work in harmony to deliver muscle relief.<\/p>\n\n\n\n And here is what we found inside the Hypervolt 2 Pro when unscrewed. Pretty much exactly all the parts from the illustration above.<\/p>\n\n\n\n Now let\u2019s break all the key components down a bit more\u2026<\/p>\n\n\n\n The motor is the heartbeat of any massage gun, a pivotal component that defines the overall performance and user experience. It’s the engine room where power meets precision.<\/p>\n\n\n\n A well-crafted motor not only determines the effectiveness of the massage by providing the right amount of force but also influences other key aspects: <\/p>\n\n\n\n There are two types of motors in massage guns:<\/p>\n\n\n\n These motors are the hallmark of higher-end massage guns. Brushless DC motors1<\/a><\/sup> stand out for several reasons:<\/p>\n\n\n\n Brands Using BLDC Motors<\/strong>: Renowned brands like Therabody<\/a>, Hypervolt<\/a>, Ekrin Athletics<\/a>, Opove<\/a>, and Achedaway<\/a> opt for brushless DC motors in their designs, indicating a commitment to quality.<\/p>\n\n<\/div>\n\n\n Found in some less expensive models, brushed motors are more traditional but come with certain drawbacks:<\/p>\n\n\n\n Usage<\/strong>: Brushed motors are commonly seen in more affordable models, including some budget-friendly options<\/a> manufactured in China, as well as in older massage gun designs. <\/p>\n\n<\/div>\n\n\n Understanding the power of a massage gun’s motor involves looking at several key metrics, each revealing a different facet of the motor’s capabilities:<\/p>\n\n\n\n Summary<\/mark><\/span><\/strong><\/p>\n\n\n\n Voltage<\/strong> and Wattage<\/strong> define the motor’s power, Stall Force<\/strong> gauges its ability for deep pressure, and RPM<\/strong> sets the massage’s speed and intensity.<\/p>\n\n<\/div>\n\n\n The percussive mechanism in a massage gun, often termed as Eccentric Rotating Mass<\/strong> (ERM) or a cam mechanism<\/strong>, is the ingenious system that turns rotation into therapeutic pulsation.<\/p>\n\n\n\n The size of the eccentric weight inside a massage gun controls how far the head moves back and forth\u2014this is called amplitude. The larger the offset, the deeper the massage, but at the expense of speed, as the head has a greater distance to travel in the same amount of time.<\/p><\/blockquote><\/figure>\n\n\n\n Here\u2019s the breakdown:<\/p>\n\n\n\n The beauty of this mechanism lies in its simplicity and effectiveness. It’s a delicate dance of physics and engineering.<\/p>\n\n\n\n Brands that excel invest heavily in research and development to balance ERM size, amplitude, and motor speed, ensuring their massage guns deliver effective deep tissue therapy without overburdening the motor.<\/p>\n\n\n\n This intricate balancing act is why there\u2019s no one-size-fits-all ‘best’ model<\/strong>. It\u2019s about finding the right harmony for each device’s intended use.<\/p>\n\n\n Author\u2019s Note<\/strong>: The percussive mechanism in massage guns, using an Eccentric Rotating Mass (ERM), transforms motor rotation into linear massage motions. The ERM’s size affects amplitude and speed, requiring a careful balance with motor RPM for effective, deep tissue massage without straining the motor.<\/p>\n\n<\/div>\n\n\n The massage gun head is where the device truly connects with you, offering tailored relief and comfort. These interchangeable heads are designed for various massage types and targeting specific body areas.<\/p>\n\n\n TIP<\/mark><\/span><\/strong> For the curious, explore our guide on massage gun heads<\/a>, their types, materials, and builds. For advice on selecting and using attachments for specific body areas, refer to this focused article<\/a>.<\/p>\n\n<\/div>\n\n\n Here, we explore the attachment mechanisms that bring this personalized touch:<\/p>\n\n\n\n This common method involves a stem on the head that snugly fits into the gun’s receptacle, often reinforced with rubber gaskets or O-rings for friction.<\/p>\n\n\n\n Pros<\/strong>:<\/p>\n\n\n\n Cons<\/strong>:<\/p>\n\n\n\n Examples<\/strong>: This method is popular among a variety of brands, particularly in more budget-friendly models, like the Opove or Achedaway<\/a>.<\/p>\n\n\n\n Some manufacturers mix it up. Case in point, Ekrin employs it in Bantam and B37 but use Push and Twist in B37S and 365.\u00a0<\/p>\n\n<\/div>\n\n\n This is less common. It involves a threaded stem on the head that screws into the gun.<\/p>\n\n\n\n Pros<\/strong>:<\/p>\n\n\n\n Cons<\/strong>:<\/p>\n\n\n\n Examples<\/strong>: Found in models like Ekrin B37s and 365<\/a>, Recovapro<\/a>.<\/p>\n\n<\/div>\n\n\n Theragun uses its own system, praised for ease of use, interchangeability across all Theragun models, and a secure fit on the stem.<\/p>\n\n\n\n Pros<\/strong>:<\/p>\n\n\n\n Cons<\/strong>:<\/p>\n\n\n\n Examples<\/strong>: Exclusive to Theragun models, recognized for their ease of use and consistent performance.<\/p>\n\n<\/div>\n\n\n Each mechanism has its pros and cons, but they all converge on one goal: to provide a customizable and effective massage experience. The choice of the attachment mechanism is a critical factor in the overall performance and user satisfaction, influencing not just the massage quality but also the ease and convenience of use. <\/p>\n\n\n\n This is why brands investing in innovative designs and reliable systems often lead the market, ensuring their devices offer both versatility and enduring performance.<\/p>\n\n\n\n Massage guns typically harness the power of Lithium-Ion (Li-ion) batteries, celebrated for their high energy density. This means they pack a substantial energy punch in a compact form, perfect for portable devices like massage guns.<\/p>\n\n\n\n Let’s break down the battery build options:<\/p>\n\n\n\n Pros:<\/strong> These batteries contribute to a sleeker design, can be lighter, and often offer enhanced protection for the battery itself.<\/p>\n\n<\/div><\/div>\n\n\n\n Cons:<\/strong> The downside is that if the battery fails or wears out, you might be looking at servicing or replacing the entire device.<\/p>\n\n<\/div><\/div>\n<\/div>\n\n\n\n Pros<\/strong>: The advantage here is the ease of replacement. You can also carry spare batteries, extending the usage time significantly.<\/p>\n\n<\/div><\/div>\n\n\n\n Cons<\/strong>: However, this can lead to a bulkier design and requires extra attention in handling and storing the additional batteries.<\/p>\n\n<\/div><\/div>\n<\/div>\n\n\n Examples<\/strong>: Models like Achedaway Pro<\/a>, Theragun Pro 4th and 5th Gen<\/a>, Hypervolt 2 Pro<\/a>, and Lifepro Sonic<\/a> use removable batteries.<\/p>\n\n<\/div>\n\n\n Regarding battery life<\/strong>, it varies based on the battery’s capacity (mAh) and how intensely the gun is used. Our tests show that on average, massage guns offer between 2 to 6 hours of use on a single charge. The charging time<\/strong> ranges from 1 to 3 hours, depending on the charger\u2019s output and the battery\u2019s capacity.<\/p>\n\n\n\n Personally, we lean<\/strong> towards built-in batteries<\/strong>, as they often lead to better ergonomic designs. Most massage guns with removable batteries stick to the standard T-Shape, which isn\u2019t always the best for grip. However, there are well-designed exceptions like the Achedaway Pro with its slightly angled handle and the Theragun Pro, where the battery is integrated into one of the triangle-shaped grips.<\/p>\n\n\n\n The control panel on a massage gun is your interface with the device, dictating how you interact with its various functions. Let’s delve into the different types of control panels:<\/p>\n\n\n\n It’s one button that does it all. Simple, easy to use, and less troublesome if it breaks. Usually, it’s a long press to turn the device on, then a click to cycle through the speeds, and a long press again to turn it off.<\/p>\n\n\n
