An Advanced Electrical Power Steering Motor (2) 2001-01-0483

Recently, EPS (Electrical Power Steering) is being widely applied in order to reduce fuel consumption and decrease installation problems of the power steering system. EPS also decreases development time and cost of the steering system due to its ease of tuning.
As we mentioned in the former paper “2000-01-0824”, the larger output motors are required. Upon developing the higher output motors, Mitsubishi realized that the EPS Systems brought about high acoustic noise, vibration, large torque ripple and friction loss.
We have developed a very silent motor based on our unique technology. This involved a very unique electromagnetic force and mechanical vibration analysis method.
Our super silent motor is so quiet, that the occupants of a vehicle can not distinguish the motor noise even when the motor is installed in the vehicle cabin.
