Description

Technical Field

[0001] This utility model relates to the field of EC wind turbine component technology, specifically an EC wind turbine controller. Background Technology

[0002] An EC fan controller is a device used to control EC fans. The core of an EC fan lies in its built-in brushless DC motor. The electronic control unit controls the current in the stator windings by detecting information from the motor position sensor, thereby achieving electronic commutation.
