The ventilator supports both volume-controlled and pressure-controlled ventilation, and is suitable for both invasive and non-invasive applications. The flexible selection of ventilation modes and settings enhances continuity of patient care. This ventilator features a compact, highly stable shaded-pole AC motor, enabling easy portability. With optimized design and high efficiency, it supports up to 3 hours of operation on battery power. The shaded-pole AC motor also supports dual voltage, making it suitable for both home-use and medical-grade ventilators.

A coffee machine rotary pump typically consists of a shaft, a rotor, a stator, and seals. When the motor drives the rotor to rotate, the cavity volume between the rotor and the stator changes periodically, generating both vacuum and pressure. The pressure regulation principle of the rotary pump relies on the rotation of the pump to adjust pressure. Specifically, when the coffee machine starts up, the rotary pump begins to operate. The rotation of the pulley causes a threaded rod to move, which in turn regulates the pressure level. Once the rod reaches the position that achieves the required pressure, the machine's pressure is set to the desired value. Inside the rotary pump, there are fan-shaped vanes. As the motor rotates, the pressure rises rapidly and progressively, capable of boosting low-pressure water to the 8–10 bar range required for espresso extraction. Even when the incoming water is not under pressure, the pump can self-prime and pressurize to maintain a stable extraction pressure. This pressure differential forces liquid to enter the pump chamber through the inlet and be delivered to the outlet. The coffee machine's pump must maintain a consistent pressure to ensure optimal brewing time, extraction quality, and flavor.

In the highly competitive commercial coffee sector, even the subtlest differences in coffee quality can impact customer experience and a store's reputation. As one of the key pieces of equipment determining coffee flavor, the coffee grinder's core component — the motor — is critical to its performance. In recent years, brushless DC motors have gradually emerged as the new preferred choice for commercial coffee grinder motors, bringing transformative changes to the coffee industry.

Brushless DC motors offer superior speed control and torque output characteristics. With precise drive control, they can adjust grinding speed (500–2,000 rpm) and torque (5–15 kg) according to different coffee bean varieties, roast levels, and barista requirements — enabling precise adjustment of grind particle size. Whether it's fine grinding for espresso or coarser grinding for French press, brushless DC motors deliver consistent, stable grinding performance to ensure every cup achieves optimal flavor and taste.
