(function and effect)
According to this example, the conducting wire 21 of electromagnetic brake 10 is brought out from electromagnetic brake 10 towards output opposite side L2.In addition,
The conducting wire 21 being brought out from electromagnetic brake 10 towards output opposite side L2 is in the output opposite side end wall for being set to motor field frame 5
It is pulled around in 15 recess portion 90, and leads to outside from the second lead division 22 of the sidewall portion 13 for being set to motor field frame 5.Whereby,
It is not necessary that gap, therefore energy is arranged between the inner peripheral surface of the sidewall portion 13 in motor field frame 5 and the outer peripheral surface of electromagnetic brake 10
Increase electromagnetic brake 10 radially with degree corresponding with above-mentioned gap is not present.Here, if making electromagnetic brake 10
Increase radially, then can increase the diameter of solenoid 78, therefore the brake force for improving electromagnetic brake 10 can become easy.This
Outside, by increasing electromagnetic brake 10 radially, the brake force of electromagnetic brake 10 can be improved, therefore, even if making electricity
Magnetic brake 10 obtains necessary brake force by electromagnetic brake 10 in the case where shortening on the direction axis L of shaft 6
It can become easy.
In addition, in this example, by the outer ring 86a of limitation bearing 86, towards outlet side L1 mobile circular protrusion 88a, (outer ring is supported
Socket part) it is configured at Chong Die with electromagnetic brake 10 position from from the direction of axis L-orthogonal.Thus, with
Circular protrusion 88a, which is located at, to be compared than electromagnetic brake 10 by the case where position of output opposite side L2, and the axis in the direction axis L can be made
It holds 86 and is located proximate to stator 8 and electromagnetic brake 10.Minimize the motor of band brake in the direction of the axisl
It becomes easy.
In addition, in this example, from output opposite side L2 be installed on the bearing (setting) plate 105 of output opposite side end wall 15 from
Output opposite side L2 is abutted with the outer ring 86a of bearing.Thus, the movement of outer ring 86a towards the outlet side L1 of bearing 86 are prominent by ring-type
88a (outer ring abutting part) limitation is played, the movement towards output opposite side L2 is limited by bearing (setting) plate 105.It is Nian Jie with using as a result,
The case where agent etc. is fixed is compared, and can be securely fixed the outer ring 86a of bearing 86 in the direction of the axisl.
In addition, in this example, passing through the output opposite side end wall 15 of motor field frame 5 and the encoder shell of encoder 3
Body 33, and the outside area of the output opposite side L2 in motor field frame 5 marks the accommodating space 34 for containing encoder main body 32.
In addition, accompanying elastic packing between the output opposite side end wall 15 and encoder housing 33 for carrying out zoning to accommodating space 34
Component 53, to be sealed in such a way that liquid will not invade accommodating space 34 from outside.Whereby, it can prevent water droplet etc. from entering
Accommodating space 34, therefore the case where making encoder 3 generate malfunction because of water droplet etc. can be prevented.
Here, in this example, the encoder main body 32 and encoder housing 33 of encoder 3 are fission.Thus, even if pressing from both sides
In the case where exporting the generation flexible deformation of flexible sealing component 53 between opposite side end wall 15 and encoder housing 33, bullet
The deformation of property containment member 53 also can only have an impact the posture of encoder housing 33, without the appearance to encoder main body 32
State has an impact.Whereby, the stress when installation of encoder housing 33 will not have an impact the magnetic detecting element of encoder, because
This accurately can detect the rotation of shaft 6 by encoder 3.
In addition, in this example, annulus 53a outer circumferential side of the shell fixing screw 48 taken the lead than flexible sealing component 53
Side, therefore even if being arranged in encoder housing 33 for the perforative shell fixing hole 49 of shell fixing screw 48, and it is exporting
The shell fixing screw hole 96 being screwed into for shell fixing screw 48 is arranged in opposite side end wall 15, will not be because of these shells
Fixing hole 49, shell fixing screw hole 96 formation and make the liquid such as water droplet invade accommodating space 34.
In addition, in this example, flexible sealing component 53 is being clipped in output opposite side end wall 15 and encoder housing 33
In the state of between flange part 45, the major diameter bore portion 101a of brake fixing hole 101 is covered from output opposite side L2
The major diameter bore portion 101a of lid, the brake fixing hole 101 is inserted into for the head of brake fixing screw 102.Thus, water
Electromagnetic brake 10 will not be because being fixed on the brake fixing screw 102 of output opposite side end wall 15 and for braking by drop etc.
The perforative brake fixing hole 101 of device fixing screw 102 and invade in motor field frame 5.In addition, because of flexible sealing component
53 include the protruding portion 53b protruded outward from annulus 53a and can be correspondingly by the position of brake fixing screw 102
It is configured at peripheral side, wherein electromagnetic brake 10 is fixed on output opposite side end wall by above-mentioned brake fixing screw 102
15.Thus, it by electromagnetic brake 10 and can be encoded using the narrow zone of the outer peripheral edge portion of output opposite side end wall 15
Device shell 33 is fixed on motor field frame 5.
