Main Configuration:

Most of the early EPS motors used brush motors. With the advancement of technology, more and more

motor manufacturers use more advanced and reliable brushless motors. However, the brushless motor

has a great difficulty in stator production. In order to ensure the circularity of the inner diameter of the

stator and simultaneously increase the slot filling rate of winding, the stator core of the stator segment

core block becomes a necessary process for almost all brushless EPS motor manufacturers.

Following photo shows a briefly describes the stator production process of EPS brushless motor

The stator of the motor manufactured by the segment-type process has excellent consistency and product

accuracy. In the actual mass production applications, the roundness of the inner circle can be controlled

to 0.03 mm or less. At the same time, because of the direct winding method, the resistance and

inductance balance of each winding of the motor are controlled to an excellent level. The high quality of

the stator determines the EPS motor's excellent performance in terms of response time, as well as

cogging torque and torque ripple. The segment stator technology is becoming the mainstream of high-

precision motor production process.
