Abstract

The invention discloses a redundant motor for an EPS steering system, comprising: a housing front end cover and a rear end cover provided with bearings for accommodating a rotating shaft, a redundant stator assembly, a redundant rotor assembly and a magnetic isolation member The two ends of the rotating shaft are installed on the bearings of the front end cover and the rear end cover of the housing, and the redundant rotor components are respectively fixed on both sides of the shaft shoulders, and the redundant stator components are respectively fixed in the housing; A redundant rotor assembly located in the redundant stator assembly, a magnetic isolation member fixed on the shaft between the redundant rotor assemblies, the magnetic isolation member is used to isolate the magnetic field between the redundant stator assembly and the redundant rotor assembly; wherein, the redundant stator The components differ by a first preset mechanical angle or a first preset electrical angle, and the relative positions of the redundant rotor components differ by a second preset mechanical angle or a second preset electrical angle. The invention can realize the double shift of the electromagnetic field of the motor space, can eliminate the torque fluctuation of the motor itself, and has high reliability and high fault tolerance.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a redundant motor used in an EPS steering system. The invention also relates to an assembly method for the redundant motor of the EPS steering system. Background technique [0002] The EPS steering system is one of the most important assemblies related to the personal safety of drivers and passengers on the vehicle. Redundant safety design must be considered to ensure that at least basic and controllable steering capabilities can be provided under any circumstances. Currently, the electric power steering system EPS is composed of an electric control part and a mechanical structure, and the electric control part of the EPS system will be driven by a motor. In the case of failure of the electronic control part of the traditional EPS system, the driver can only drive the steering through the mechanical structure such as the pipe column, which is undoubtedly a difficult problem for the dr...
