AI Technical Summary
Technical Problem
In the prior art, when the three-phase wire sequences of the input and output terminals of the three-phase wiring terminals do not match, it is necessary to redesign the stator winding of the motor or the IGBT module of the motor controller, resulting in high cost and high difficulty.
Method used
By crossing the copper strips in the three-phase wiring base, the first end and the second end of the copper strips have different three-phase wiring sequences, thereby adapting to the mismatched three-phase wiring sequence.
Benefits of technology
Redesigning the motor stator winding or IGBT module is avoided, reducing costs and difficulty, and achieving suitable conditions for mismatched three-phase line sequences.

Abstract
The utility model relates to a three-phase wiring seat and an electric drive system, and the three-phase wiring seat comprises three copper bar members; the injection molding part wraps the three copper bar parts, the first end parts of the three copper bar parts are arranged on the same side, and the second end parts of the three copper bar parts are arranged on the sides opposite to the first end parts; wherein at least two of the three copper bar pieces are arranged in a crossed manner, so that the three-phase line sequence of the first end parts of the three copper bar pieces is different from the three-phase line sequence of the second end parts of the three copper bar pieces. According to the utility model, the three-phase wiring seat provided by the invention is just suitable for the condition that the three-phase line sequences of the stator winding of the motor and the IGBT module of the motor controller are not matched, and the stator winding of the motor or the IGBT module of the motor controller is prevented from being redesigned. Therefore, the problems of high cost and high difficulty caused by redesign can be avoided.
