Abstract
The utility model relates to a motor, in particular to a structure for reducing the temperature rise of the motor, specifically being a low-temperature lifting motor. The utility model comprises a machine base and a stator core which is fixed on the machine base. A conductive heat layer pad which is made of a silicone grease material is arranged between the machine base and the stator core. With the conductive heat layer pad, the microcosmic contact area of the stator core and the machine base is increased and the air between the two is defecated, therefore, the heat resistance is reduced, the thermal conductivity is improved and the aim of reducing the temperature rise of the motor is achieved. In the utility model, by additionally equipping a conductive heat layer pad between the machine base and the stator core of the motor, the thermal conductivity between the stator core (heating element) and the machine base (heating radiating element) of the motor can be increased, the ability of the heat emitting in the motor can be further increased and improved, therefore, the utility model has the effect of reducing the temperature rise of the motor and the effect of reducing the temperature rise of the motor is highly significant.
Description
Technical field
The utility model relates to motor, and particularly the structure of the reduction temperature rise of motor is specially a kind of low temperature lifting motor.
Background technology
Motor is a kind of electric energy is converted into mechanical energy or mechanical energy is converted into the device of electric energy, exists energy loss between transition phase, and this loss is converted into heat energy, and the temperature of motor is raise.The height of electric machine temperature rise directly influences the insulation life of motor.Therefore, electric machine temperature rise is an index of paying close attention to and make great efforts reduction in design of electrical motor, manufacturing and the use.Prior art has the measure of the reduction electric machine temperature rise of multiple routine, as can reach the purpose of reduction electric machine temperature rise by rational Electromagnetic Design, by the cooling system of motor itself.But the measure of conventional reduction temperature rise can not fully temperature rise be reduced to sometimes desirable degree.
Summary of the invention
The utility model solves the problem that further reduces electric machine temperature rise, and a kind of motor---low temperature lifting motor that reduces the temperature rise new construction that has is provided.
The utility model is to adopt following technical scheme to realize: the low temperature lifting motor, comprise support and the stator core of being fixed on the support, and between support and stator core, be provided with the heat-conducting layer pad that forms by heat conductive silicon grease material.Increase the microcosmic contact area of stator core and support by this heat-conducting layer pad, got rid of air between the two, thereby reduced thermal resistance, improved heat conductivity, reached the purpose that reduces electric machine temperature rise.
The utility model is by setting up the heat-conducting layer pad between the support of motor and stator core, increased the heat conductivity between electric machine stator iron (heater element) and the support (heat dissipation element), further improved and improved the emission capabilities of motor internal heat, thereby have the effect that reduces electric machine temperature rise, and the effect highly significant of electric machine temperature rise reduction.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of low temperature lifting motor described in the utility model;
Embodiment
The low temperature lifting motor comprises support 2 and the stator core 1 of being fixed on the support, is provided with the heat-conducting layer pad 3 that is formed by heat conductive silicon grease material between support 2 and stator core 1.
