Radiating structure of torque motor

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 ...

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 distance equivalent to the thickness of the iron core. The excessively long conduction path is obviously not conducive to the dissipation of heat energy, and it is easy to accumulate too much heat energy around the coil and affect the efficiency of energy conversion
