Application
The precision voice coil motor for ventilators is suitable for hospital ICUs (rapid response to respiratory signals to protect critically ill patients), emergency transfers (lightweight adaptation to portable models to resist bumps and ensure air supply) and home rehabilitation (precise adjustment of parameters to assist long-term treatment), providing precise power support for ventilators with rapid response and stable operation.
Quality Control
The core materials of the common parts of voice coil motors are strictly controlled, the coils are precisely wound, and the magnetic circuit system is calibrated to ensure uniform magnetic field. The assembly follows high-precision alignment standards, passes multiple rounds of environmental and mechanical tests, and has stable dynamic response. Full inspection before leaving the factory ensures reliable quality.
Service
Voice coil motor services run through the entire product life cycle. Detailed technical consultation is provided before sales, and selection and matching are assisted based on application scenarios; real-time follow-up of production and logistics is carried out during sales to ensure efficient and accurate delivery; after sales, rapid response to needs is provided, installation guidance and troubleshooting support are provided, and the quality assurance system is linked to solve problems, ensuring the stable operation of the equipment in all aspects.
