Vector Control (FOC): Through Field-Oriented Control (FOC), the stator current of the motor is decomposed into d-axis (flux component) and q-axis (torque component), enabling independent decoupling control of flux and torque. This allows AC motors to achieve precise speed regulation characteristics similar to DC motors, with typical speed accuracy of ±0.1% and millisecond-level response time.
V/C Control Logic: Combines voltage/current dual closed-loop control to dynamically adjust output voltage and frequency, maintaining constant flux (avoiding weak flux losses) while optimizing current waveforms to reduce harmonic losses and enhance system efficiency.
High-Frequency Inverter Technology: Adopts IGBT/SiC power modules to support output frequencies above 500Hz, suitable for high-speed motor drive scenarios (e.g., robotics, CNC machine tools).
Performance Advantages
Precision Torque Control: Achieves ±1% torque accuracy through independent regulation of d/q-axis currents, ideal for precision machining, robotic joint drives, and similar applications.
Energy Efficiency Improvement:
System Efficiency Exceeding 95%: Combining permanent magnet direct-drive motors with vector inverters, this solution saves 20%-40% energy compared to traditional asynchronous motor + reducer systems, with system efficiency reaching over 97% (e.g., 28.6% energy savings in chemical reactor stirring retrofits).
Intelligent Energy Optimization: Built-in self-learning algorithms dynamically adjust voltage/frequency based on load, avoiding "over-sizing" idle losses; supports regenerative braking energy feedback to reduce grid load.
High Reliability Design:
Maintenance-Free Structure: Eliminates reducers, couplings, and other intermediate components, reducing failure rates by 60% and extending maintenance intervals to 30,000 hours (e.g., permanent magnet direct-drive motor solutions).
Environmental Adaptability: Fully sealed structure resists chemical corrosion, with motor lifespan exceeding 100,000 hours; high-temperature demagnetization protection (operating temperature ≤180°C).
Application Scenarios
- Industrial Automation: Precise speed regulation and energy-saving control for conveyor belts, pumps, fans, and other equipment.
- High-End Equipment: Robotic joint drives, CNC machine tool spindles, elevator traction systems.
- New Energy & Transportation: Wind/solar power converters, electric vehicle drive systems, rail transit traction.
- Special Industrial Scenarios: Chemical reactor stirring (e.g., permanent magnet direct-drive motors replacing traditional reducer systems for energy savings + cost reduction), precision instrument processing.
