Electrical machine

Technical Field

The application relates to the technical field of motors, in particular to a waterproof setting of a motor wire outlet.

Background

An Electric machine (also known as "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction. The motor is represented by a letter M (old standard is D) in a circuit, the main function of the motor is to generate driving torque which is used as a power source of electrical appliances or various machines, the generator is represented by a letter G in the circuit, and the main function of the generator is to convert mechanical energy into electric energy. Generally, the motor is a circular device, for example, a gear disc is added to drive a gear system. When the motor works, data monitoring or transmission needs to be carried out on various parameters of the motor, so that the motor usually needs to be externally connected with other equipment, and the connection is generally carried out through a wire. In addition, the motor is generally used with an encoder, the encoder is used for weaving the rotating speed of the motor into high and low level analog signals through a grating, and the high and low level analog signals are used as signal sources to be fed back to a control system, such as a server, so that the server knows the rotating speed of the motor and can control the speed of the motor or control other links to be matched with the speed of the motor. In other words, the motor is an actuator, the encoder feeds back a signal of the motor to the servo driver, so as to implement a closed-loop control system, and the data of the encoder needs to be conducted through a wire.

According to some embodiments of the present application, fig. 1 is a schematic structural view of a motor outer casing 100 according to some embodiments of the present application, and fig. 2 is a schematic first view of the motor outer casing 100 according to some embodiments of the present application. Referring to fig. 1 and fig. 2, the motor outer casing 100 includes a motor end cover 10, a motor casing 20, and a fastening device 50 fixedly connecting the motor end cover 10 and the motor casing 20. The outer housing 100 is further provided with an outlet 30 for the lead wire 40 to enter and exit.

With continued reference to fig. 1 and 2, the wire 40 is a flexible glue-bound wire. In some possible embodiments, the flexible glue line comprises enameled wires sheathed with a flexible glue line sheath. The flexible wire means a multi-strand metal core wire produced by using a multi-strand or single-strand metal wire (generally, a copper wire) as a core and using soft rubber as an insulating sheath. Generally, in order to ensure the softness of the flexible stranded wire, the sectional area of the core of the flexible stranded wire is not too large. The wire includes motor wire and temperature-sensing line.

The number of the wires is one or more, the wires can be arranged as required, and the cross section of the outlet 30 is only required to be smaller than that of the wires. The reason is that the adhesive flexible wire has the characteristic of being deformed by compression, when the section size of the outlet 30 is smaller than that of the lead, the lead can be extruded to cause the deformation of the lead, so that the motor wire and the temperature sensing wire are extruded in the outlet 30 of the motor shell, a sealing state is further achieved, and an effective sealing and waterproof effect is generated.

According to some embodiments of the present application, fig. 3 is a schematic structural view of a motor end cover 10 according to some embodiments of the present application, fig. 4 is a first view of the motor end cover 10 according to some embodiments, fig. 5 is a second view of the motor end cover 10 according to some embodiments, and fig. 6 is a third view of the motor end cover 10 according to some embodiments. As shown in fig. 3, the motor end cover 10 has a recess 11 for mounting other devices and a mounting hole 51 for mounting a fastening device 50, and an outlet 30 is provided at a contact position of the motor end cover 10 and the motor housing 20. As shown in fig. 4, 5 and 6, the outlet 30 has a certain width D. In some embodiments, the width D of the wire outlet 30 is smaller than the diameter of the wire 40, so that when the wire 40 passes through the wire outlet 30, the wire 40 can be just clamped in the wire outlet 30 by the installation of the fastening device 50, and the wire outlet 30 has no gap due to the deformation of the outer glue of the wire 50, thereby achieving the waterproof and dustproof effects. In some embodiments, the wire 40 has a plurality of wires. In other possible embodiments, the conducting wires 40 include one or more motor wires 41 and a temperature sensing wire 42, in which case, the conducting wires 40 sequentially pass through the outlet 30 side by side, the width of the outlet 30 is slightly smaller than the total diameter of the conducting wires 40, and the height of the outlet is slightly smaller than the diameter of one conducting wire, so that after the fastening device 50 fixes the motor end cover 10 and the motor casing 20, there is no gap in the outlet 30 due to the deformation of the outer glue of the conducting wires 50, thereby achieving the waterproof and dustproof effects.

According to some embodiments of the present application, fig. 7 is a schematic structural view of a motor case 20 according to some embodiments of the present application, fig. 8 is a first view of a motor case according to some embodiments of the present application, and fig. 9 is a second view of a motor case according to some embodiments of the present application.

In other embodiments, the appearance opening 30 is formed by the motor end cap 10 and the motor housing 20. As long as the size of the outlet 30 is smaller than the cross-sectional size of the wire 40. The waterproof sealing silica gel glue that needs to add of current outlet or use the sealing rubber piece, and production processes increases, and the cost is increased, and the outlet 30 of this application with wire 40's setting need not use sealed glue, and the simple cost of process is low.

The motor outer casing 100 of the present application has versatility, and can be used for installation of motors that generally require waterproofing. The motor body can be a general motor body, and is not limited in the application.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
