The assembly periphery of rotor core and magnet steel.
Further, described rotor core is splicing structure, and is fan-shaped, and described rotor core relies on the location every magnetic axis set
The locator protrusions of groove and magnet steel sheath carries out positioning and fixing, simultaneously location and fixed rotor magnet steel.
Further, described magnet steel sheath and every magnetic axis set all use non-magnet material.
Further, the interior outside direct contact surface of described magnet steel is non-magnet material, has cut off the leakage field of rotor magnetic steel
Road, forces rotor magnetic steel magnetic flux by air gap and winding linkage, reduces motor flux leakage and lead to, add motor main flux.
Compared with prior art, the invention has the beneficial effects as follows: the invention provides a kind of pin-connected panel EPS brushless electric machine and turn
Minor structure, this structure uses locating slot and magnet steel sheath positioning convex every magnetic axis set to fix magnet steel and assembled iron core.Cut off
EPS brushless electric motor rotor magnet steel leakage field path, forces rotor magnetic steel magnetic flux by air gap and winding linkage, reduces motor flux leakage
Logical, add motor main flux thus improve power of motor density and efficiency.
