Through the setting of this structure, signal line, power cord etc. lead wires on the control panel pass through the through-hole earlier and enter into in the casing, pass the wire hole again and stretch out outside the casing, and the wire hole shaping of this structure is on the end cover for the drawing forth of lead wire is more convenient, and if offer the wire hole on the casing, because have stator and rotor in the casing, the lead wire is in the in-process of outwards drawing forth easily with stator and rotor take place to interfere.
In the above-mentioned control board mounting structure of a motor, the outer side surface of the end cover is provided with a thickened portion, and the thickened portion is internally provided with a plurality of wire outlet holes.
Through the setting of this structure, because the thickness of end cover is thinner, the setting of thickening portion conveniently sets up a plurality of wire holes on the end cover for different leads can be followed different wire holes and outwards drawn forth.
Compared with the prior art, the control panel mounting structure of the motor has the following advantages: the middle part of end cover inwards sunken in this structure forms the mounting groove, again with the control panel setting in the mounting groove, is equivalent to the control panel and realizes embedded design on the end cover, and the shroud covers the control panel and plays the effect of keeping apart and protecting the control panel, and this structure does not increase the end cover basically along motor axial thickness, and then has reduced motor along axial length for the overall structure of motor is compacter and small and exquisite more, reduces the space of the duty of motor, makes things convenient for the installation of motor.
