Get Down with the Teardown: Magic Wand Original

Today, I’m going to show you the “magic” inside the Magic Wand Original. Ha. The Magic Wand was formally better known as the Hitachi Magic Wand until Hitachi decided to remove themselves from the product a while back once it became less of a back massager and more of a fun massager. It’s been one of the most popular personal massagers since the 1960’s due to its fantastically strong vibrations. As an engineer (and a person who drools over the “How It’s Made” show) let’s nerd out and figure out how this baby works. Presenting our very first “Get Down with Teardown”: The Magic Wand. 


Here’s the unpackaged Magic Wand with its nice and blue box that says “Powerful, penetrating vibrations. Relaxes sore muscles, helps relieve tension” It definitely relieves a little somethin’ somethin’…

The plug-in wand retails at $60, the rechargeable wireless one at $125.

With a bit of pulling, the friction-fitted spongy head cover comes off, exposing the metal casing wrapped in electrical tape. The metal casing holds the motor’s counterweight inside to resonate the vibration to the spongy head cover. 

Something that tickles my engineering feathers: the metal casing is threaded so that it can screw on directly to the thick coil spring. So clever! This thick coil spring helps dampen the vibration coming from the metal casing in order to reduce the vibration you feel when holding the handle. 

After taking out four screws, here’s the metal casing! Having a closer look at what looks like ejector pin flashes, I speculate that the metal casing was die casted.

On the left side of the casing there are bearings and a counter weight that rotate to create the vibration. The actual motor itself sits inside the plastic handle portion. The motor and the counterweight are connected by the small spring, to create a nice rumble-type of vibration. On the right side of the casing, there’s a black rubber gasket that borders the casing to create a tight, compressed seal once the two sides of the casing are assembled. 

Here’s a snapshot with the counterweight assembly removed from the metal casing. There are two metal brackets that sit inside the casing to cradle the ball bearings on the counterweight assembly. Also, I didn’t expect to find SO MUCH grease inside to help smooth the counterweight’s rotation. My team is thrilled I got black grease all over the table.


Now, onto the handle portion. Here we see the two halves of the injection molded plastic casing. There’s a giant motor that sits towards the top, the HIGH/OFF/LOW switch at the center, and the plug that power the entire thing coiled at the bottom.  

Tickling of my engineering feather part 2: the Magic Wand is known for a bit of overheating issues if left on for over 20 minutes. They were obviously aware of this issue and they engineered a solution. The engineers took advantage of the motor having to rotate the counterweight anyways and added a white plastic fan onto the motor as well as an attempt to cool down the motor. Loving it.  

Here’s the electronics pulled out. The motor SN3658-220-GHSF is a 6600 RPM, high voltage brush motor made by Igarashi Motors USA. The switch is a fairly standard ON-OFF-ON rocker switch.  

Don’t laugh, but I attempted to draw the circuit diagram to clarify what’s going on for all the electrical folks out there.  


And there you have it, folks. The ever so popular Magic Wand in exploded view. 

Thanks for getting down with the teardown!
