description The invention relates to a method for detecting an initial angle of a ferrite reluctance synchronous motor based on zero current control, which comprises the following steps of: taking a ferrite auxiliary reluctance synchronous motor as a research object, rotating the motor through initial constant-current frequency conversion, changing into a direct-axis and quadrature-axis zero-current control strategy after reaching a set speed, and controlling the initial angle of the ferrite reluctance synchronous motor within a set time, the compensation angle is increased according to the set slope, the scanning interval is 180-180 degrees, the compensation angle corresponding to the maximum value of the direct-axis voltage is recorded as an angle I, the compensation angle is reduced according to the set slope, the scanning interval is + 180-180 degrees, the compensation angle corresponding to the maximum value of the direct-axis voltage is recorded as an angle II, and the average value of the angle I and the angle II
