Technical Advantages

CLK Self-Locking

• Employs CLK self-locking phase speed control to achieve ultra-precise speed regulation (<0.01% fluctuation) for high-speed fans

Parameter Identification

• Enhanced low-speed observer enables single-parameter startup tuning

• Ensures reliable initialization across diverse motors, loads, and system configurations

Tuning-Free Algorithm
Offline Identification:

• ≤10% parameter estimation error

• Unified firmware supports all motors within same series
  Online Identification:

• Real-time motor parameter monitoring

• Derived temperature estimation enables thermal protection
  Eliminates dependency on LCR meters for factory motor testing

Reverse-Wind Braking (Negative Current Handling)

• Proprietary braking control achieves full-speed reverse-wind operation

• Maintains safe current levels during braking (vs. conventional methods)

Efficiency Self-Adaptation

• Back-EMF zero-cross detection via windowing method

• Automatic electrical angle alignment

• Streamlines debugging by eliminating complex matching procedures

• ual Control Mode

• Partial-speed FOC Control + Full-speed FOC/Square-wave Hybrid Switching

• Implements field-oriented control (FOC) at partial speeds

• Automatically switches to square-wave modulation at full speed
