Problems solved by technology

[0005] However, since this technology is to arrange the cooling pipeline on the outer end surface of the iron core element away from the motor shaft, the heat energy generated by the coil adjacent to the motor shaft must be transferred through a conduction dista

Embodiment Construction

[0022] see Figure 1 to Figure 4 As shown, the heat dissipation structure 10 of the torque motor provided in a preferred embodiment of the present invention includes an iron core 20, a cooling portion 30 made of non-magnetic material and a plurality of coils (not shown in the figure) out).

[0023] The iron core 20 is generally ring-shaped, and is a conventional motor element formed by stacking silicon steel sheets. Generally speaking, it takes a central axis as the axis, and a plurality of teeth 21 spaced apart from each other are arranged radially. Grooves 22 are formed between the teeth 21 around the central axis.

[0024] The cooling part 30 has a first end plate 31 and a second end plate 32, which are similar in shape to the end faces of the iron core 20 located at both ends of the central axis, and are fixed on the shaft of the iron core 20 with one side of the plate respectively. On the end faces of both ends, and make each of the end plates 31, 32 similar to each of ...

Abstract

The invention discloses a radiating structure of a torque motor. The radiating structure comprises an iron core, a cooling portion and a plurality of coils; the iron core is provided with a plurality of teeth which are outwardly radially arrayed around a center shaft and are separated from one another; the cooling portion is made from non-magnetic-conductive materials and is provided with a first end plate and a second end plate, the shape of the first end plate and the shape of the second end plate are respectively similar to shapes of two end surfaces of the center shaft of the iron core, the first end plate and the second end plate are respectively attached to the two end surfaces of the center shaft of the iron core, and first fluid flowing space and second fluid flowing space are respectively arranged in the end plates; and the coils are respectively wound on the teeth and adjacent plate protrusions. Cooling mechanisms of the radiating structure of the torque motor are in direct contact with the coils, a heat conduction path is shortened, the heat conduction efficiency is improved, and accordingly a radiating effect is improved.

Description

technical field [0001] The invention relates to a torque motor, in particular to a heat dissipation structure of a torque motor. Background technique [0002] A motor is a technology used to convert electrical energy into kinetic energy, and the performance of kinetic energy can be presented by power and speed. A perfect motor completely converts the input electrical energy into kinetic energy that is output outward, but in fact, the energy conversion It cannot reach 100%. Therefore, under the first law of thermodynamics, what is not converted in the form of kinetic energy will be output in other forms, and most of it will be consumed in the form of heat energy. This is the inevitable heat generation in motor technology question. [0003] However, there is an inverse relationship between the operating efficiency of the motor and the temperature. The higher the temperature of the motor is, the greater the reluctance effect will be, which will reduce the operating efficiency ...
