Description

Technical Field

[0001] This utility model relates to the field of electromagnetic structure technology for motors, and in particular to an electromagnetic structure for a motor. Background Technology

[0002] An electromagnetic rotor is an important component in an electric motor (such as a generator or electric motor) used to generate a magnetic field or induced electromotive force. It typically consists of a rotor core and rotor windings. By allowing current to flow through the windings, a magnetic field is generated, thereby realizing the electromagnetic energy conversion of the motor.

[0003] In existing motor electromagnetic structures, the windings are usually clamped inside the rotor, with the windings at both ends of the rotor forming a single unit. However, in actual use, installing the windings requires completely inserting them into the rotor, which is quite cumbersome. Furthermore, disassembling the rotor requires cutting the windings, resulting in broken windings that are difficult to recycle. Therefore, we propose a new motor electromagnetic structure.

[0028] Example:

[0029] Reference Figure 1-4 This utility model provides an electromagnetic structure for an electric motor, including a rotating rod 1. Several second rotor cores 3 are provided on the outer side of the rotating rod 1. A first rotor core 2 is fixedly connected to the middle of the outer side of the rotating rod 1. A rotor winding 4 is movably inserted into the inner side of the first rotor core 2 and the second rotor core 3. A fastener 5 is movably sleeved on the outer side of the end surface of the rotor winding 4.

[0030] Among them, the outermost second rotor core 3 is fixedly connected to a connecting and mounting assembly 6, and a stabilizing assembly 7 is provided on one side of the connecting and mounting assembly 6.

[0031] The rotor winding 4 includes a winding body 41, with a connecting terminal 42 fixedly connected to one end of the winding body 41. A connecting top block 43 is fixedly connected to one top end of the connecting terminal 42. A fixing inclined surface 45 is provided on one side of the top of the connecting top block 43. The winding body 41, the connecting terminal 42, and the connecting top block 43 are in close contact with the inner sides of the first rotor core 2 and the second rotor core 3, so that the connecting terminal 42 can be inserted into the inner sides of the second rotor core 3 and the first rotor core 2. The connecting terminal 42 and the winding body 41 are installed, and the connecting terminals 42 are mated together to connect the winding bodies 41.

[0032] The top of the connecting top block 43 is provided with a fixing groove 44, which makes it easy to insert a tool into the inner side of the fixing groove 44 to move the connecting top block 43, the connecting terminal 42 and the winding body 41, so as to facilitate insertion into the inner side of the first rotor core 2 and the second rotor core 3, making the operation convenient.

[0033] The fastener 5 includes a movable limiting sleeve 51, with a fixing groove 52 on the inner side of the movable limiting sleeve 51, a fixing plane 53 at the end of the movable limiting sleeve 51, and threaded holes 54 symmetrically provided at the end of the movable limiting sleeve 51. A movable connecting block 55 is attached to the surface of the fixing plane 53, and a fastening bolt 56 is provided between the movable connecting block 55 and the movable limiting sleeve 51. The outer side of the connecting top block 43 is attached to the inner side of the fixing groove 52, so that the movable limiting sleeve 51 can be fitted onto the outer surface of the connecting top block 43 under the action of the fixing groove 52. Then, the movable connecting block 55 and the fixing plane 53 are attached to each other, and the movable connecting block 55 and the movable limiting sleeve 51 are connected and fastened by the fastening bolt 56. This allows the movable limiting sleeve 51 to connect and fasten the connecting top block 43, thereby connecting and fastening the connecting terminals 42, and thus connecting the winding bodies 41. The operation is convenient.

[0034] The connection and installation assembly 6 includes a third rotor core 61. Threaded posts 62 are provided at equal intervals on one side of the third rotor core 61. The winding body 41, the connecting terminal 42, and the connecting top block 43 are in contact with the inner side of the third rotor core 61. A fastening nut 63 is provided on the outer surface of the threaded post 62, so that the stabilizing assembly 7 can be fitted onto the outer surface of the threaded post 62 and connected and fastened by the fastening nut 63.

[0035] The stabilizing component 7 includes a movable end plate 71. A connecting rod 73 is provided on one side of the movable end plate 71. Fixed through holes 72 are equidistantly opened inside the movable end plate 71. The connecting rod 73 fits against the inner side of the second rotor core 3 and the third rotor core 61, so that after the winding body 41 and the connecting terminal 42 are inserted into the inner side of the fixed through hole 72, the connecting top block 43 and the top end of the connecting terminal 42 are welded together to form a connection. Then, the connecting rod 73 is inserted into the inner edge of the second rotor core 3 and the third rotor core 61, and at the same time, it is sleeved on the outer surface of the threaded column 62 to form a stable connection, which is convenient to operate.

[0036] The working principle of this utility model is as follows: First, the winding body 41 and connecting terminal 42 are inserted into the inner side of the fixing through hole 72. Then, the connecting top block 43 is welded to the top end of the connecting terminal 42. Next, the winding body 41 and connecting terminal 42 are inserted into the inner edge of the second rotor core 3 and the third rotor core 61. Then, a tool is inserted into the inner side of the fixing groove 44 to move the winding body 41 and connecting terminal 42, allowing the winding body 41 to be inserted into the inner edge of the second rotor core 3 and the third rotor core 61, so that the connecting terminals 42 and the connecting top blocks 43 are in contact with each other. Then, the connecting rod 73 is inserted into the inner edge of the second rotor core 3 and the third rotor core 61, while the movable end plate 71 is in contact with the third rotor core 61, so that the movable end plate... 71 is fitted onto the outer surface of the threaded post 62 and fastened to the threaded post 62 by the fastening nut 63. Finally, the movable limiting sleeve 51 is fitted onto the outer surface of the connecting top block 43 under the action of the fixed slot 52. Then, the movable connecting block 55 and the fixed plane 53 are fitted together and fastened to the movable connecting block 55 and the movable limiting sleeve 51 by the fastening bolt 56. This allows the movable limiting sleeve 51 to connect and fasten the connecting top block 43, thereby connecting and fastening the connecting terminals 42. This enables the winding body 41 to be connected. The operation is convenient. When disassembling the winding body 41 in the future, only the stabilizing component 7, the fastener 5 and the connecting terminal 42 need to be disassembled, which can avoid damage to the winding body 41. The overall structure is simple and the operation is convenient and quick.
