Application of Nidec 20M Series DC Brushless Motor in Air-Conditioned Clothing. Compared with the 13H series motor, its volume is reduced by 30%, power doubled to 4W, torque increased to 5mNm, and it supports 5–18V wide-voltage battery drive, perfectly balancing portability and cooling performance.

As the massage gun market shifts from unregulated expansion​ to quality-driven competition, the motor—the core power source—faces mounting pressure to deliver miniaturization, lower noise, and superior stability.

Precision optical loads place extremely stringent demands on motors: color wheels and Fresnel lens disks require high radial runout precision to prevent optical path drift; polygon mirrors and diffraction disks rely on ultimate rotational speed stability to ensure scanning linearity.

NIDEC 13H series is a DC brushless motor with dimensions of ∅24.2 × 19.1 mm, featuring a built-in driver circuit and an output power below 3W.

NIDEC 22H Series is a brushless DC motor measuring ∅35.8 * 40mm, featuring a built-in drive circuit with an output power of <15W.
