On the rear and front end face of rotor, on an end face of the motor stator uniformly installation there are three Hall sensor,
Read head processing circuit is installed on the other end of the motor stator, reflective code-disc is installed on the rotor drive end bearing bracket
Or multistage magnet ring, through-hole is designed in the middle part of the rotor drive end bearing bracket, reflective code-disc or multistage magnet ring, and the conducting wire group is successively
Pass through the through-hole in the middle part of rotor drive end bearing bracket, reflective code-disc or multistage magnet ring and respectively with motor stator, Hall sensor,
The connection of read head processing circuit.
For hub motor, there is winding, and winding has coated stator whole surface on stator, above-mentioned patent
Read head processing circuit is mounted on winding surface, and usual read head processing circuit is adhered directly on winding by glue, winding table
Face is more prismatic, and non-flat configuration, at work, winding generate a large amount of heat, impact at this time to read head processing circuit,
And glue easily softens, and causes read head processing circuit along the run-off the straight of winding surface, read head can not be aligned reflective code-disc or
Multistage magnet ring, the final signal that reflects is not accurate enough, especially influences on the higher use occasion of required precision more serious.
Utility model content
In view of the deficiencies of the prior art, the utility model provide it is a kind of make carry read head wiring board be not directly anchored to
Winding surface, but a metallic support is added, read head remains in situ during hot operation, guarantees that read head and reflection are compiled
Code-disc is in normal position, accurately has the hub motor of encoder to signal-obtaining.
To achieve the above object, the utility model provides following technical solution: a kind of hub motor with encoder,
Including motor shaft, stator, rotor and end cap, winding is provided on stator, stator is fixed on motor shaft, and rotor is located at stator
Outer ring is provided with metallic support on the motor shaft, wiring board is fixed on the metallic support, reading is provided on wiring board
Head, the end cap are equipped with the reflection code disk matched with read head.
The further metallic support is made of stainless steel.
The further wiring board is fixed by screws on metallic support.
The further metallic support includes for the flat part of fixing circuit board and for the set with motor axis connection
Canister portion, the sleeve part are covered on motor shaft and are interference fitted.
There are gaps between the further flat part and winding.
Compared with prior art, the utility model has the beneficial effects that being arranged the wiring board with read head in metal branch
On frame, metallic support is directly anchored on motor shaft rather than on winding, and wiring board is fitted on metallic support always at work,
Metallic support can't deformation occurs due to high temperature, and read head is made to be in initial position always, avoids run-off the straight and leads to not
It is directed at reflection code disk；Wiring board is fixed by screws on metallic support simultaneously, and fixation is very secured, guarantees wiring board and reading
Head is in initial position, and the gap between metallic support and winding can make the temperature of metallic support lower than winding, reduce to route
The influence of plate.
