Title:
VIBRATION REDUCTION METHOD, MOTOR, NEUTRALIZER, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/235548
Kind Code:
A1
Abstract:
A method for reducing vibrations in an electric power steering device to which a typical motor is attached includes: a step for determining the frequency of vibrations to be reduced in the electric power steering device, which is the frequency of the vibrations produced by the motor; and a step for setting the properties of a neutralizer provided on the housing of the motor in a manner such that the transfer function of the system from the source of vibrations in the motor to the coupling part between the motor and the electric power steering device is provided with properties which suppress the vibrations in the coupling part at the determined vibration frequency.
