Integrated busbar assembly, motor controller, motor assembly, electric assembly and vehicle

The utility model discloses an integrated busbar assembly, a motor controller, a motor assembly, an electric assembly and a vehicle. The integrated busbar assembly comprises a first conducting bar and a first connecting column; the first connecting column is connected with the first end of the first conducting bar, the axial direction of the first connecting column is basically perpendicular to the first conducting bar, and at least part of the periphery of the first connecting column is sleeved with a magnetism gathering magnet. According to the motor controller, the magnetism gathering magnet sleeves the first connecting column, so that the occupation of the magnetism gathering magnet on the internal mounting space of the motor controller can be effectively reduced, the length of the first conducting bar is reduced, the longitudinal space of the motor controller is fully utilized, and the space utilization rate is improved.
