Open-loop Vector Drive

 

When your application requires high torque at low speeds but doesn't necessitate the complexity of a sensor-based system, our Open-loop Vector Drive is the ideal solution. We have engineered this drive to provide superior motor response compared to traditional V/F control by using advanced mathematical models of the motor. This allows for smoother acceleration and better speed regulation in standard packaging tasks. As a manufacturer with 10 years of experience, we have optimized this drive for reliability and cost-efficiency, making it a favorite among our domestic and international distributor partners.

 

The Open-loop Vector Drive is designed for simplicity and durability. It operates on a standard 220V power supply and is capable of driving 0.75kW asynchronous motors with high efficiency. The DB9 signal interface ensures a secure connection to your control system, reducing the risk of signal interference in noisy industrial environments. At our Wuxi facility, we utilize multi-zone reflow ovens and AOI inspection to ensure that every Open-loop Vector Drive we produce is built to last. We back this with a 3-year warranty and the expertise of our 4-person R&D team to support your integration needs.

FAQ

Q: What is the difference between this and the closed-loop version?

A: The open-loop drive does not require a feedback sensor, making it more cost-effective for applications where speed accuracy is less critical.

Q: Can it be used with 380V motors?

A: This specific model is rated for 220V; however, we can provide custom solutions for 380V requirements.
