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…

The electric anti-decubitus air mattress uses pressure sensors to control the alternating inflation and deflation of 54 air cells, achieving dynamic pressure ulcer prevention, low noise, oil-free operation, back support, and adaptive pressure relief for intelligent care.

By changing the motor drive from 120° square wave to 180° sine wave commutation, the current spikes during phase switching are fundamentally eliminated, reducing noise from 50.4 dB to 39.3 dB — a reduction of 10 dB — achieving significant noise suppression.

Sensorless servo motor based on High-Frequency Injection (HFI).​ This motor has no encoder or Hall elements. Its built-in chip estimates rotor position via HFI, enabling pulse+direction closed-loop control. Featuring low cost, compact size, and excellent zero/low-speed performance, it is ideal for precision devices such as medical pumps.

For electric wheelchair applications, Nidec has focused on improving low-speed, high-torque performance and optimizing energy efficiency, while maintaining or even reducing the motor's size and weight. This makes it better suited to meet the requirements of modern electric wheelchairs in terms of hill-climbing ability, driving range, and control precision.

The automatic door motor series consists of φ65 BLDC motors combined with WORM / inline planetary / right-angle planetary gearboxes, covering an output range of 60W to 260W. Key advantages include IP54 protection, long service life, high torque, short door-opening time, manual operation during power failure, and flexible configuration to suit different door types.

Leveraging its 42 mm form factor, built-in driver, approximately 70 W output, high efficiency, and low noise, the Nidec 24H SP43-40—when coupled with a gearbox and lead screw—effectively meets the thrust, speed, precision, and volumetric requirements of CT high-pressure injectors. It is particularly well-suited for new product development of dual-channel compact CT high-pressure injectors and the retrofit of conventional equipment.

As the endpoint of the smart grid, smart electricity meters are seeing their automatic reclosing and remote on/off functions gradually become standard. Behind these seemingly simple operations lies a sophisticated micro-drive system providing essential support.

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.
