Description
Technical Field
The utility model relates to the technical field of motors, in particular to an insulating framework convenient for uniform winding and a motor thereof.
Background
The stator bobbin generally includes a coil bobbin for winding a wire and a terminal bobbin for mounting a conductive terminal. Generally, the stator bobbin is generally one molded integral piece, that is, the coil bobbin and the terminal bobbin are integrally formed by molding. In the manufacturing process of the motor, an integrally formed stator frame is usually pressed into the stator, then a wire (e.g., an enameled wire) is wound on the coil frame to form a coil, then a lead end of the coil is pressed into a wire pressing groove on the terminal frame, and finally, a conductive terminal is pressed into a conductive terminal groove on the terminal frame so as to be electrically connected with the lead end of the coil.
The wire winding portion of conventional skeleton is smooth, and the distribution is inhomogeneous when so wire winding is arranged, can lead to the full rate of groove to reduce, and the moment of motor diminishes.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem in the background technology, the utility model discloses an insulating framework convenient for uniform winding and a motor thereof.
The utility model provides an insulating framework convenient for uniform winding, which comprises a framework, wherein a winding part of the framework is provided with a plurality of uniformly distributed winding grooves.
The winding slot is used for positioning the coil, so that the coil is uniformly wound on the winding part, the slot fullness rate is improved, and the torque performance of the motor is improved.
In order to explain the concrete structure of the framework, in the scheme, the winding part is U-shaped, the two ends of the winding part are respectively provided with the first baffle and the second baffle, and the first baffle and the second baffle are both protruded out of the winding end of the winding part.
The traditional winding grooves are distributed on the straight end face of the winding part, so that the winding firmness of the coil is lower, the problem is further solved in an improved mode, and particularly, the winding grooves are formed in the corners of the winding part. So set up, the winding wire groove distributes on two adjacent terminal surfaces of wire winding portion, and the coil winding is more firm.
Furthermore, the winding groove and the end face connected with the winding groove form an included angle of 45 degrees. So set up, the coil atress is even.
In order to explain the specific structure of the winding groove, in the scheme, the axial projection of the winding groove is arc-shaped. The winding groove is in a minor arc shape. So set up, the wire winding groove is higher with copper line laminating degree, and copper line winding is more firm.
In order to improve the utilization ratio of the winding portion, in the scheme, the winding grooves are fully distributed in the width direction of the winding portion.
The utility model also provides a motor which comprises a stator, wherein the stator is provided with an insulating framework convenient for uniform winding and used for winding coils.

The winding slot 2 positions the coil, so that the coil is uniformly wound on the winding part 11, the slot fullness rate is improved, and the torque performance of the motor is improved.
The second embodiment:
compared with the first embodiment, the differences are as follows: the winding grooves 2 are arranged at the corners of the winding part 11 and are symmetrically distributed in two groups. So set up, winding groove 2 distributes on two terminal surfaces that winding portion 11 is adjacent, and the coil winding is more firm.
Example three:
compared with the two examples, the difference is that: as shown in fig. 3, the winding groove 2 forms an angle of 45 ° with the end face to which it is connected. So set up, the coil atress is even.
Example four:
compared with the first embodiment, the differences are as follows: the winding grooves 2 are distributed in the width direction of the winding part 11, thereby improving the utilization rate of the winding part 11.
Example five:
compared with the three phases of the embodiment, the differences are as follows: as shown in fig. 4, the winding slot 2 has a minor arc shape in axial projection. So set up, wire winding groove 2 is higher with copper line laminating degree, and the copper line winding is more firm.
Example six:
the utility model also discloses a motor which comprises a stator, wherein the stator is provided with any one of five insulation frameworks 1 which are consistent in embodiment and are convenient for uniform winding, and the insulation frameworks are used for winding coils.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
