Embodiment 1

[0033] For the stator hybrid cooling structure of the dual-rotor stator yokeless modular axial motor, it is divided into two parts: the stator support structure, the heat pipe, and the water-cooling hybrid cooling structure:

[0034] Embodiment 1 The first part of the stator support structure includes two high-strength plastic plates on the upper and lower sides and two metal rings on the inner and outer sides. The plastic plates are made of plastic materials with high mechanical strength such as polyether ether ketone, embedded in the top of the stator teeth, and two The metal is made of aluminum alloy, and the plastic plate and the metal ring are connected by bolts to support and fix the stator parts, such as figure 1 , figure 2 As shown in the plastic plate (1) and the metal ring (2), inside the stator bracket, the gap between the stator armature and the cooling structure is filled with epoxy resin with excellent thermal characteristics to fully fix the stator unit;

Embodiment 2

[0037] The first part of the stator bracket of this embodiment is the same as that of Embodiment 1. The second part of the heat pipe and water-cooling hybrid cooling structure, when the gap between the stator modules is insufficient, only place the flat heat pipe in the gap, and place the water-cooling pipe on the outside of the stator module. Multi-layer two-way parallel water-cooling pipes are used and connected with heat pipes, the temperature of the stator is only transferred from the heat pipes to the water-cooling pipes, such as Figure 4 as shown, Figure 5A schematic diagram of the arrangement structure of multi-layer bidirectional parallel water cooling pipes under the structure of this embodiment is given. 5-1 and 5-2 are parallel cooling water channels with the same structure, but the direction of water flow in the pipes is opposite, forming a complementary structure. To ensure uniform temperature distribution of the stator.

Abstract

The invention discloses a stator hybrid cooling structure of a double-rotor stator yokeless modular axial motor, which includes a stator armature, a stator bracket and a cooling structure. The stator armature includes a yokeless stator core and windings, and the stator core is divided into Block structure, the winding is a three-phase concentrated winding, the stator bracket is composed of two high-strength plastic plates on the upper and lower sides and two metal rings on the inner and outer sides, the flat heat pipe and the water cooling pipe are combined to form a cooling structure, inside the stator bracket, the flat heat pipe and the water cooling The pipes are combined to form a cooling structure, and the multi-layer two-way grouping type two-stage parallel water-cooling pipe arrangement is adopted. The invention utilizes the characteristics of the flat heat pipe and combines the specially designed complementary water-cooling structure to improve the stator temperature distribution of the dual-rotor stator yokeless modular axial motor, disperse the stator temperature of the motor, and improve the cooling performance of the motor, using materials such as plastic plates The stator bracket is made to reduce the overall weight of the stator under the premise of ensuring the mechanical strength.

Description

technical field [0001] The invention relates to the field of motors, in particular to a stator hybrid cooling structure of a double-rotor stator yokeless modular axial motor. Background technique [0002] In recent years, with the rise of high-tech products such as CNC machine tools, industrial robots, manipulators, electric mopeds, computers and their peripheral equipment, and the needs of special applications such as tracking systems such as radar and satellite antennas, higher requirements have been put forward for servo drive motors. Performance indicators and requirements for thin mounting structures. At the same time, with the continuous improvement of people's living standards, especially the calls for miniaturization, thinning and low noise of household appliances are getting higher and higher, and new requirements are put forward for the structure and volume of the motor. [0003] In order to meet the needs of industry and people's life, disc permanent magnet motor...
