Problems solved by technology

Therefore, it is necessary to reasonably design the structure of the armature assembly, taking into account the winding and embedding technology of high-precision windings and solving the cooling structure and heat shielding technology, which is very challenging. At present, there is no mature structural form in China.

Embodiment 1

[0024] Embodiment 1: the sandwich structure straight line or planar motor armature of this direct liquid cooling and thermal shielding (a pair of very lower structural sections refer to figure 1 ) includes a thin box-shaped armature assembly composed of a thin sealed box 1 and multiple sets of pancake-shaped armature windings 2 placed in the thin sealed box 1 . There are a plurality of support frames 5 in the sealed box 1 to fix the armature winding 2, and gaps 6, 7 for forced circulation of cooling liquid are formed between the cavity wall of the sealed box 1 and the upper and lower surfaces of the armature winding 2. The upper and lower sides of the thin box-shaped armature assembly are two magnetic pole assemblies 3, 4 respectively.

Abstract

The invention relates to a direct liquid cooling and heat shielding type sandwich-structured motor armature. A thin box-shaped armature assembly of a motor is formed by arranging pancake-shaped windings into a cavity of a thin sealing box made from electrical insulating, magnetic isolating and thermal insulating materials; and a gap for forced circulation of cooling liquid is formed between two surfaces of an armature winding and cavity walls of the sealing box. Direct liquid cooling is performed on the surfaces of the armature winding, so that heat consumed by copper of the armature winding is fully taken away by the cooling liquid. The direct liquid cooling and heat shielding type sandwich-structured motor armature of the invention has the advantages of avoiding the influence of temperature change on a control system and control precision, ensuring positioning precision of the system, along with compact structure and good cooling effect, and is suitable for high-tech sophisticated sport equipment and special semiconductor electronic equipment.

Description

technical field [0001] The invention relates to a cooling structure of a motor armature, in particular to a direct liquid cooling structure with good thermal shielding between the sandwich structure motor armature and the surrounding environment. Background technique [0002] The sandwich structure motor refers to a planar motor or a disc rotating motor with an armature assembly in the middle and a magnetic pole assembly on both sides. In order to improve the thrust (or torque) density of the motor, the gap between the two magnetic pole assemblies of the sandwich structure motor must be as small as possible, and the armature assembly generally needs to be thin. In recent years, the sandwich structure permanent magnet motor has become the first choice for driving components in high-tech cutting-edge sports equipment and semiconductor electronic special equipment due to its advantages of high positioning accuracy, high thrust (or torque) density, high electromechanical frequen...
