CONSTRUCTION
A low inertia, low noise, and high power output brushless type power steering motor is used.
The power steering motor consists of a rotor, stator, motor shaft and rotation angle sensor.
The rotation angle sensor consists of a highly reliable and durable resolver sensor. The rotation angle sensor detects the rotation angle of the motor and outputs it to the power steering ECU assembly. As a result, it ensures efficient EPS control.
The torque that is generated by the power steering motor assembly is transmitted via the joint to the reduction mechanism.
The wheel gear is made of a high strength, low friction, and low wear plastic material, to realize low noise and a lightweight construction.
A worm gear supported by ball bearings is used. Also, a leaf spring is provided to ensure optimal gear engagement at all times.
