Compared with electrically excited motors, permanent magnet motors excel with an array of distinguished advantages:
High efficiency
By eliminating excitation system losses, our permanent magnet motors achieve a substantial efficiency boost of 5-12%. Featuring a high power factor, excellent torque inertia ratio, reduced stator current, and minimized stator resistance loss, they deliver unparalleled control and direct drive capability. This means no speed slip, no bearing issues, and no connection transmission woes. Efficiency is increased by more than 3%, and impressive gains of 15-35% over similar asynchronous motors are observed, even under light loads. Achieve superior energy efficiency, compliant with the national level 1 energy efficiency standards.
Low noise
Our compressors are designed with a sophisticated magnetic field, ensuring optimal magnetic density distribution and offering a vast operating frequency range. The result is notably reduced operational noise, paired with genuine constant air pressure thanks to our open loop vector control. With a swift response time of less than 50ms, the system adeptly adjusts gas production swiftly across a wide spectrum.
Compact structure, small size, light weight, high precision, and rapid response
The innovative design excludes the need for exciting winding and power supply (magnetic pole core), thus simplifying the structure, enhancing operational reliability, and making maintenance a breeze.
High starting torque
Our permanent magnet synchronous motors boast a starting torque and overload capacity that are a power level above those of three-phase asynchronous motors. With a remarkable maximum starting torque to rated torque ratio exceeding 3 times, these motors surpass the general asynchronous motor's capability, which only reaches 1.6 times, providing superior start-up performance and reliability.
