The invention relates to a motor mechanism and an electric power steering apparatus. The motor mechanism comprises a housing which is internally provided with a first installation cavity and a second installation cavity which are communicated with each other; the motor is contained in the first mounting cavity, a magnet is arranged on the motor, and the magnet is located at the end, facing the second mounting cavity, of the motor; the control assembly is contained in the second mounting cavity and comprises a logic printed circuit board and a power supply printed circuit board which are connected, in the axial direction of the motor, the logic printed circuit board is closer to the magnet than the power supply printed circuit board, and the logic printed circuit board is provided with a motor corner chip and a main chip; the motor corner chip is used for sensing rotation of the magnet and generating a sensing signal, and the sensing signal is transmitted to the main chip through the logic printed circuit board. According to the motor mechanism and the electric power steering device, signal transmission can be more reliable and stable.
