Abstract
The utility model relates to an external motor with a plurality of Hall sensors. An external rotor and Hall sensors are respectively arranged outside the motor body; the motor rotor and the external rotor are coaxially arranged; the Hall sensor and the external rotor are relatively arranged; a protective cover is arranged outside the Hall sensors and the external rotor; three leading wires extend from the upper parts of the Hall sensors, and the three leading wires are respectively connected with a positive electrode of the power supply, a negative electrode of the power supply and a controller; each Hall sensor is provided with a corresponding controller interface; the controller is arranged inside a junction box outside the motor; and the leading wires led from the Hall sensors are connected with the interfaces on the junction box. The Hall sensors of the motor are arranged outside the stator groove; in the case when the Hall sensors are damaged, the protective cover outside the motor only needs to be opened for replacing the sensors, and the stator does not need to be removed deliberately, thereby saving the time of disassembling the motor, and bringing great convenience to industrial production.
Description
Technical field
the utility model relates to the motor that a kind of transmission is used, especially the motor of a plurality of Hall elements of external band of convenient for maintaining and dismounting.
Background technology
at present, known motor only embeds Hall element in the motor stator groove, after Hall element damages, the stator of motor must be removed, taking out Hall element from stator slot changes again, both affected industrial efficiency, also wasted manpower, and brought inconvenience to the use of motor.
The utility model content
be not easy to the problem of maintenance in order to overcome the Hall element embedded in existing motor stator groove, the utility model provides the motor of a plurality of Hall elements of a kind of external band, the Hall element that this motor comprises is placed on the outside of stator groove, after Hall element damages, the protective cover that only need open outside motor is replaceable, without specially stator being taken off, saved the time of dismounting motor, to industrial production, bring great convenience.
the utility model solves the technical scheme that its technical problem adopts: this motor mainly comprises terminal box, stator, rotor, casing, Hall element, outboard rotor and protective cover, outside motor body, be respectively equipped with outboard rotor and Hall element, rotor and outboard rotor are coaxially installed, Hall element installation corresponding to outboard rotor, be provided with protective cover outside Hall element and outboard rotor, three lead-in wires are stretched out on the top of Hall element, connect respectively positive source, power cathode and controller, each Hall element is provided with the interface of corresponding controller, controller is located in the terminal box of outside motor, the lead-in wire of drawing from Hall element is connected with the interface on terminal box.During motor rotation, outboard rotor and rotor coaxial rotation, Hall element can obtain the position signalling of rotor by the position signalling that detects outboard rotor, in addition, if Hall element is damaged, only need open the protective cover of motor stator outside, the Hall element more renewed gets final product, thereby has reached effective purpose that improves industrial production efficiency.
the beneficial effects of the utility model are, the Hall element that this motor comprises is placed on the outside of stator groove, after Hall element damages, the protective cover that only need open outside motor is replaceable, without specially stator being taken off, saved the time of dismounting motor, brought great convenience to industrial production.
The accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is described in further detail.
fig. 1 is structural principle schematic diagram of the present utility model.
in Fig. 1,1. terminal box, 2. stator, 3. rotor, 4. casing, 5. Hall element, 6. outboard rotor, 7. protective cover.
Embodiment
in Fig. 1, this motor mainly comprises terminal box 1, stator 2, rotor 3, casing 4, Hall element 5, outboard rotor 6 and protective cover 7, outside motor body, be respectively equipped with outboard rotor 6 and Hall element 5, rotor 3 is coaxially installed with outboard rotor 6, Hall element 5 installation corresponding to outboard rotor 6, be provided with protective cover 7 outside Hall element 5 and outboard rotor 6, three lead-in wires are stretched out on the top of Hall element 5, connect respectively positive source, power cathode and controller, each Hall element 5 is provided with the interface of corresponding controller, controller is located in the terminal box 1 of outside motor, the lead-in wire of drawing from Hall element 5 is connected with the interface on terminal box 1.During motor rotation, outboard rotor 6 and rotor 3 coaxial rotation, Hall element 5 can obtain the position signalling of rotor 3 by the position signalling that detects outboard rotor 6, in addition, if Hall element 5 is damaged, only need open the protective cover 7 of motor stator 2 outsides, the Hall element 5 more renewed gets final product, thereby has reached effective purpose that improves industrial production efficiency.
