The utility model relates to permagnetic synchronous motor, particularly relates to the paster hall position sensing arrangement on a kind of rotating shaft for being arranged on permagnetic synchronous motor and rear end cap.
Background technology
Hall in conventional motors or built-in structure, or Hall band pin, or magnet ring adopts the radial magnetizing structure of burst.These structures or Yin Huoer are arranged in stator slot, in heavy load situation, easily produce interference, and motor generate heat rapidly after easily cause Hall element damage and cannot normally work; Or Yin Huoer is with pin, when mounted fragile pin, part uses qualification rate low; Or because adopting the radial magnetizing structure of burst to cause production efficiency low, and cost is high.
Utility model content
The purpose of this utility model, exactly in order to solve the problem, provides a kind of paster hall position sensing arrangement.
In order to achieve the above object, the utility model have employed following technical scheme: for being arranged on rotating shaft and the rear end cap of permagnetic synchronous motor, comprises for being arranged on holder assembly in rotating shaft and for being arranged on the Hall subassembly on rear end cap; Described holder assembly comprises holder and magnet ring, and magnet ring is fixed on holder; Described Hall subassembly comprises Hall Plate and paster Hall, and paster Hall is pasted onto in Hall Plate.
The one side of described magnet ring is with self-adhesive, magnet ring is directly bonded on holder by self-adhesive, corresponding mark groove is respectively equipped with on magnet ring and on holder, allow the mark groove on magnet ring and the mark groove on holder aim at time bonding, be consistent to make the main magnet steel polarity in magnet ring polarity and electric machine rotor iron core; Described holder assembly to be sleeved on machine shaft and to lock.
Described paster Hall totally 3,3 paster Halls are along the circumferential direction pasted onto in Hall Plate by phase angle regular uniform.
Described Hall Plate has kidney slot, and Hall subassembly is tightened by bolts on rear end cap by this kidney slot.
Described paster Hall is arranged on being right against on the face of magnet ring of the baseplane of Hall Plate, and is in the position being right against magnet ring.
Described holder assembly is not less than 1mm towards the axial distance of the end face distance rear end cap of shaft extension side.
The distance of reaction of described paster Hall and magnet ring is 1 ~ 3mm.
