EC Synchronous Motor Measured Waveform Diagram

DC Positioning + IF Start + FOC Solution

DC Positioning + IF Start + FOC Solution: Rated load start, requiring low-frequency start and stable load characteristics. Enables extremely low-frequency constant-load start.

High-Frequency Injection Positioning + IF Start + FOC Solution:

High-Frequency Injection Positioning + IF Start + FOC Solution: The high-frequency voltage injection method injects a high-frequency voltage signal into the motor. The motor model superimposes the high-frequency voltage signal onto the fundamental frequency component generated by FOC. The induced high-frequency current is then processed to obtain speed and rotor position information. This positioning method can achieve positioning even when the motor is stationary.

DC Positioning + Direct FOC Start:

DC Positioning + Direct FOC Start: Direct FOC start for large loads, eliminating the IF running state.

Adaptive Disturbance Algorithm:

Adaptive Disturbance Algorithm: Handles fluctuating or periodic load changes. Optimized anti-disturbance algorithm ignores motor load changes, ensuring long-term stable motor operation.
