Rotasonic歯ブラシ：1基のサーボモーターで多彩なブラッシング動作

Rotasonic歯ブラシ：1基のサーボモーターで多彩なブラッシング動作

A rotasonic toothbrush is Relish Tech’s flagship brushing platform. A single servo motor drives a shaft that can swing through selected angles from 0 to 360° or rotate in a full circle. This flexible drive supports sweep, oscillation and sonic vibration, with whitening and polishing actions on the 5-in-1 configuration. This guide explains the technology and compares the two Rotasonic platforms.

Rotasonic歯ブラシとは？

Rotasonic combines rotation and vibration through one servo motor. Its drive shaft can swing through selected angles from 0 to 360° or make a full rotation, allowing a rotasonic toothbrush to support several cleaning actions on the same platform. The enabled actions depend on the model and configuration.

The Rotasonic platform combines sonic vibration, sweeping and oscillation, with whitening and polishing on the 5-in-1 model. This range of movements gives brands a clear all-in-one product story and room to build different configurations.

1基のモーターで5つの清掃動作

サーボ軸が自由に動くため、同じRotasonic歯ブラシで、一定の動きに限らず複数の清掃動作を切り替えられます。

各清掃動作の内容

• Sonic. Bristle motion at 31,000 vibrations per minute (VPM) cleans through direct contact and moves liquid and foam around the teeth and gumline.
• スイープ。低周波のスイープ動作で毛先を歯面に沿って動かし、直接的な機械的ブラッシングを行います。
• 往復運動。ヘッドが広い弧を描いて往復し、従来の回転式歯ブラシのような動作範囲を生み出します。
• ホワイトニング。専用の動作で歯の表面の着色汚れに働きかけ、より明るい仕上がりを目指します。
• Polish. A full 360° rotation provides a polishing action. The brush head or polishing attachment should match the selected product configuration.

The product pages specify a rotation speed of 900–2,300 RPM and a sonic vibration rate of 31,000 VPM. Rotation and vibration are distinct measurements; together they describe the movement capabilities of the Rotasonic platform.

Rotasonic・Vibrosonic・ソニックの比較

These platforms use different combinations of movement. Sonic brushes clean through vibrating bristles and the liquid movement they create. Relish Tech’s Vibrosonic platform combines sonic vibration with a 60° oscillation. Rotasonic uses a servo shaft that can swing through selected angles or rotate fully, supporting sweep, oscillation and sonic actions, plus whitening and polishing on the 5-in-1 model.

Illustrative Comparison of the Three Platforms

Research on powered toothbrushes provides useful background. The American Dental Association (ADA) explains that both manual and powered toothbrushes can clean effectively. The 2014 Cochrane review by Yaacob and colleagues found benefits for powered brushing in plaque and gingivitis outcomes. A 2020 review of powered-toothbrush design discusses how construction and use affect performance. These sources address the wider category rather than a clinical evaluation of Rotasonic. For the dual-motion platform, see our guide to Vibrosonic technology.

Rotasonic製品ラインアップ

Both Rotasonic configurations include an LCD smart display, a 2,000 mAh battery with a stated runtime of up to 30 days, and an IPX8 waterproof rating. Runtime depends on the brushing settings and usage; the IPX8 specification follows the depth and duration defined for the model.

• VS0560B（3-in-1）は、スイープ、往復運動、音波振動を組み合わせ、5+1種類のクリーニングモード、ワイヤレスおよびUSB-C充電、900～2,300 RPMの回転速度に対応します。
• VS0661C（5-in-1）はフラッグシップモデルです。スイープ、往復運動、音波振動にホワイトニングと研磨の動作を加え、Type-C充電に加えて磁石式の壁掛け充電にも対応します。

どちらもOEMおよびプライベートラベル向けのプラットフォームです。同じRotasonic歯ブラシの基本構成を、購入者のブランドに合わせた色、ブラシヘッド、パッケージで提供できます。

サーボ軸によって変わること

The practical value of the Rotasonic design is flexibility. Brands can configure enabled actions, mode profiles, displays and finishes around their market and retail positioning. The servo-driven platform supports a range from sweep, oscillation and sonic vibration to the 5-in-1 model with whitening and polishing, giving OEM buyers more than a single fixed specification to work with.

ブランド向け：Rotasonicプラットフォーム

For OEM and private label buyers, the Rotasonic toothbrush is a distinctive flagship option within the electric toothbrush range. Its combination of cleaning actions and visible LCD features suits brands developing a premium lead product.

Rotasonicがラインアップの中心となる理由

• 多機能を一体化した価値を伝える。「1つのヘッドで5つの清掃動作」は、単一動作の歯ブラシにはない店頭での訴求点です。
• 3-in-1と5-in-1のラインを用意する。VS0560BとVS0661Cにより、同じプラットフォーム内でエントリーモデルとフラッグシップモデルを展開できます。
• LCDを差別化要素にする。スマートディスプレイにリアルタイムのブラッシングデータを表示する機能は、製品の上質感をわかりやすく伝えます。
• 仕上げをブランドに合わせる。パントンカラーの指定とシリコーン・ナイロン毛の組み合わせにより、既存ブランドのデザインに合わせやすくなります。

On commercial terms, the standard MOQ for customized products is 1,000 units; smaller orders may be discussed case by case. Wholesale orders for in-stock products start at 50 units. Samples ship in 3–7 days, and mass production runs 25–35 days after approval; a one-time mold fee of $500–$3,000 applies only to a new custom casing and is fully refundable once cumulative orders reach 5,000 units within 12 months. The factory is ISO 9001 and ISO 13485 certified with FDA establishment registration, and can supply CE, RoHS, FCC, and UKCA documentation plus EU design-patent coverage for the platform.

Those specifications are measured rather than quoted. Our own reliability laboratory, which has logged more than 450 test items over nine months, verifies the servo-driven motion stroke by stroke on every unit, confirms the sonic vibration rate to a factory specification of 30,000 ± 3,000 strokes per minute, and runs each handle through a 72-hour full-unit life test, immersion testing per GB 4208-2017, and 48-hour salt spray per GB/T 2423.17-2008. The 3.7 V lithium cell in the handle was cycle-tested at 0.5 C to a ≥80 % retention acceptance criterion at 300 cycles and measured 98.6 % of its initial capacity. This result records cell-capacity retention under the stated test conditions. Reports are available on request.
