Abstract
The utility model relates to a self-testing motor for stator and rotor friction, which comprises a stator, a rotor and a protector, wherein, the rotor is sheathed on the inner part of the stator; a casing is provided with the protector; the internal wall of a stator winding of the motor is provided with a detected contact sheet; the detected contact sheet is connected with a wire; the wire is connected with the protector arranged on the outside part of the casing. The utility model has the advantages of simple and compact structure, convenient installation and operation, low cost, and sensitive response.
Description
The utility model belongs to electric machinery, specifically is a kind of stator and friction rotor self check motor.
Present motor; in order to increase the service life; disposed the kinds of protect device; major part is the phase failure to motor; the protective device of aspects such as overload; these protective devices have also all played positive effect to the protection of motor; but for bending because of motor shaft; the caused stator of the damage of bearing; friction rotor and cause motor coil to burn phenomenon not have protective effect; at this situation; the motor that the designer causes the buckling phenomenon of the wearing and tearing of bearing and motor shaft damages and has designed some protective devices; but cover owing to be mounted in the outer end of motor more; and need to obtain working power from motor power with being equipped with dedicated transformer; so there is complex structure; install and use inconvenience, reliable in action is relatively poor, the defective that reaction is sensitive inadequately.
The purpose of this utility model act as and prevents because of the stator that motor shaft bending, wearing and tearing and damage of bearings cause, the damage that friction rotor causes motor, and provide a kind of simple and compact for structure, easy to install, cost is low, sensitive stator and friction rotor self check motor.
The utility model is achieved through the following technical solutions:
Be a kind of stator and friction rotor self check motor, comprise stator, rotor and protector, rotor is sleeved in the stator; protector is installed on the casing; installation and measuring contact on the motor stator winding inwall detects contact and connects lead, and lead is connected with casing protector outward.
Described detection contact is inlaid in the stator slot wedge surface.
Described detection contact is installed in the stator core surface.
The winding inwall symmetry of described motor stator is installed 2～12 and is detected contact, and each detects contact and links together by lead.
The winding inwall symmetry of described motor stator is installed 3～10 and is detected contact, and each detects contact and links together by lead.
The winding inwall symmetry of described motor stator is installed 4～6 and is detected contact, and each detects contact and links together by lead.
Described detection contact symmetry is installed in apart from the stator core inwall at motor output power end 1/5～1/3 place.
The utility model compared with prior art, since adopted will detect the contact symmetry be fixedly mounted on the motor stator winding inwall, and the setting height(from bottom) that detects contact flushes with stator rabbet, detect contact and be connected with electric machine casing lead outward, so have the following advantages:
1, simple and compact for structure, easy to install.
2, be quick on the draw.
3, low cost of manufacture.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model embodiment mounting structure synoptic diagram.
Fig. 2: the utility model embodiment mounting structure synoptic diagram.
Among the figure: 1 motor cabinet, 2 stators, 3 leads, 4 detect contact, 5 slot wedges, 6 iron cores
When motor manufacturing or maintenance, to scribble earlier the detection contact 4 of insullac as shown in Figure 1 and Figure 2, slot wedge 5 surfaces that are installed to motor 1 stator or iron core 6 surfaces of symmetry, after motor uses a period of time, can regularly pass through multimeter, the lead 3 that detects on the contact 4 be linked to each other with motor cabinet 1, then the rotor of rotary electric machine, whether the rotor and the stator that just can detect motor have friction phenomenon, at any time motor is safeguarded; Also available wire 3 will detect the outer protector of contact 4 and motor 1 housing and be connected; when the running of the rotor of motor 1 undesired; when rubbing mutually with stator 2; detection contact 4 on elder generation's friction stator 2; after insullac on the detection contact 4 is worn away; just make the outer protector of electric machine casing form the loop; motor power is cut off in the protector action; thereby motor is protected; because of rotor and stator 2 are prone to friction most at 1/5～1/3 stator place of distance power take-off; be installed in herein so will detect contact 4 symmetries, detect how much can being decided according to the actual requirements of contact quantity, detect and draw after contact 4 available wire are connected as a single entity.
