Description
Technical field
The utility model relates to a kind of compact structure variable-frequency motor of built-in encoder, be specially adapted to European crane and lightweight crane, motor and reductor are suspended on crane transverse beam, require the axial dimension shortening motor, improve the occasion of the total tune of jack machinism.
Background technology
European crane and lightweight crane motor are variable-frequency motor mostly, because variable-frequency motor has speed adjusting performance widely, and a lot of application scenario all needs accurate location, this just needs configuration codes device to detect the rotating speed of motor, the signals such as position angle, because motor afterbody is assembled with brake, fan (blower fan) etc., encoder is installed again and just seems that motor axial dimension is very long, not only affect the harmony of jack machinism, and cause motor easily to cause the harmful effects such as vibration when running up, therefore the axial dimension shortening motor is needed.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure variable-frequency motor of built-in encoder, shortens the axial dimension of motor.
The technical solution of the utility model is achieved like this: the compact structure variable-frequency motor of built-in encoder of the present utility model comprises motor stator, rotor, end cap, motor main junction box, bearing, in cavity inside end cap, encoder is installed, encoder rotor is fixed on rotor, encoder stator is fixed on end cap rear portion, and encoder lead-in wire is directly introduced in motor main junction box.
Rotor external part outside end cap installs brake.
Described encoder stator is arranged on the reinforcement of bearing with end cover room by encoder shell fragment.
The compact structure variable-frequency motor of described built-in encoder, the rotor external part outside end cap installs brake.
Advantage of the present utility model: the utility model installs encoder in the cavity of end cap, owing to just make use of this empty cavity position, does not need to increase extra encoder supporting construction, so do not increase the axial length of motor and encoder assembling is simple.Encoder is arranged on the axial length that motor internal decreases motor, makes the structure of motor compacter.

Embodiment
As shown in Figure 1, the compact structure variable-frequency motor of built-in encoder of the present utility model comprises motor stator 1, rotor 2, end cap 3, motor main junction box 4, bearing 5, in cavity 6 inside end cap 3, encoder is installed, encoder rotor 7 is fixed on rotor 2, rotate together with rotor 2, encoder stator 8 is fixed on end cap rear portion, and encoder lead-in wire 11 is directly introduced in motor main junction box 4.Rotor 2 external part outside end cap 3 installs brake 15.14 is end rings.
Fig. 2, Fig. 3 are end cover structure schematic diagrames, and Fig. 4, Fig. 5 are coder structure schematic diagrames:
Because motor main junction box 4 needs to be arranged in end cap plane, therefore cover internal can form a cavity 6, and the effect of cavity 6 not only can hold end winding, and can install encoder.The effect of bearing with end cover room reinforcement 10 not only can improve rigidity and the intensity of bearing chamber, and can as the mounting plane of encoder shell fragment 9.
Encoder stator 8 is arranged on the reinforcement 10 of bearing with end cover room by encoder shell fragment 9, is fixed by encoder shell fragment mounting screw 13.
Motor stator 1 is made up of stator punching, do not have support, therefore motor main junction box 4 must be arranged on end cap 3, and determining end cap 3 needs a long cavity, one is because end winding is inside end cap cavity, and two is because motor main junction box 4 needs longer mounting plane.If encoder is contained in after brake 8, an encoder bracing or strutting arrangement is just needed to be used for regular coding device, the axial length of motor can be made to increase a lot, and brake belongs to the equipment wanting frequent care and maintenance, the assembling of encoder can affect the care and maintenance of brake.
The utility model just utilizes the cavity 6 in end cap 3, encoder rotor 7 is arranged on rotor 2, by encoder rotor lock-screw 12 regular coding device rotor 2, encoder stator 8 is arranged on the bearing chamber reinforcement 10 of end cap 3 by encoder shell fragment 9, fixed by encoder shell fragment mounting screw 13, encoder lead-in wire 11 is directly introduced in motor main junction box 4, this mounting structure had not both increased any unnecessary supporting construction, and just make use of the empty cavity position of end cap, do not increase the axial dimension of motor, make the structure of motor compacter.
