This document provides a comprehensive overview of NIDEC's current mass-produced diaphragm pump lineup. Classified by transfer medium into air and liquid pumps, it serves as a clear guide for users during the selection process.

NIDEC small diaphragm pumps are divided into gas pumps and liquid pumps. Production in China began around 2010. With the…

With the maturation of Sensorless Positionable Brushless DC (BLDC) motors, peristaltic pumps have gained an extremely cost-effective upgrade solution.

The sensorless positionable BLDC motor solution has limited accuracy, but as long as it meets the application requirements, it is a highly cost-effective choice.

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.

For the same brushless DC motor, this paper compares and analyzes its TI-TN curves at multiple voltages including 6V, 7.4V, 9V, and 12V, and provides an in-depth analysis of the correlation patterns among speed, current, and efficiency.

With a service life of thousands of hours, more stable speeds, and higher efficiency, brushless DC motors are the optimal solution for commercial clipper applications.

After pressurizing a sealed container to the target value and shutting down the pump, a gradual pressure drop is observed within the container, leading to suspicions of an air leakage defect in the pump itself.

The current testing method is highly efficient, low-cost, and easy to automate. However, when applied to diaphragm water pumps operating with water as the medium, it harbors an overlooked logical flaw: passing an air leak test at 40 kPa does not guarantee the absence of water leakage at 90 kPa.

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.

During product testing and feedback from field applications, we observed that Brushless DC diaphragm pumps exhibit significant abnormal noise under specific negative pressure conditions. Initially, this issue was often misdiagnosed as aerodynamic noise or assembly defects. However, a detailed analysis of the motor’s force dynamics revealed that the root cause lies in the destabilization of the "equilibrium point" between the pump’s compression load and the motor’s magnetic thrust at certain vacuum levels.

In medical testing equipment, the body fixation and inspection of microfluidic chips and biosensor chips, as well as their automated loading, unloading, and handling, all rely on a stable, clean, and compact micro vacuum source.

The alcohol fireplace uses a diaphragm pump to quantitatively transfer bioethanol from the storage tank to the combustion trough (some atomizing fireplaces also use it as a supply pump).

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.

The NIDEC 24H series positionable brushless motor is essentially an all-in-one low-cost servo that integrates a brushless motor, encoder, driver IC, and microcontroller into a φ42 mm motor housing.

To facilitate quick selection for engineers, this article provides a systematic overview of NIDEC's mainstream stepper linear motor offerings for design reference.
