Problems solved by technology

[0002] The main heating area of ​​the motor stator is the stator coil, and the heat dissipation path of the stator coil is usually through the motor stator core to transfer heat to the motor shell to realize the heat dissipation of the stator coil. The existence of gaps will reduce the heat conduction efficiency, and the heat conduction path will be too long to limit the heat conduction efficiency, which will greatly affect the heat dissipation effect, thus limiting the maximum output power of the motor and affecting the improvement of the power density of the motor. In addition, because the coil is wound There will be gaps more or less, making the coils loose, and the stator coils will vibrate during the operation of the motor, which increases the noise of the motor

Embodiment approach

[0018] Such as figure 1 Shown is a schematic diagram of the heat dissipation structure of the motor of the present invention. The motor includes a casing 1, a stator 2, a rotor 3, a motor shaft 4, and a coil 5. Most of the heat generated by the rotor 3 and the motor shaft 4 during operation is It is transmitted to the stator 2 through other media such as air or oil, and is transmitted to the casing 1 by the stator 2 to dissipate heat. For the stator 2 itself, its main heating element is the coil 5, while the traditional The heat dissipation path of the motor stator is: coil, skeleton, stator core, and casing, and there is an air gap in the above path, that is, there is a need to transfer heat through air between adjacent components. Such a heat dissipation path is too long and the efficiency is low, and When the heat generated by the rotor of the motor is transferred to the stator, the heat of the stator is often large and the heat dissipation is not timely. In order to solve ...

Abstract

The invention discloses a heat dissipation structure of a motor. Heat-conducting glue is injected between the outer surface of the coil and the casing to directly transfer the heat of the coil to the casing, thereby shortening the heat conduction path and improving the heat dissipation effect of the motor. Resin glue prevents the coil from vibrating during motor operation and reduces motor noise.

Description

technical field [0001] The invention relates to a motor structure, in particular to a heat dissipation structure of a motor stator. Background technique [0002] The main heating area of ​​the motor stator is the stator coil, and the heat dissipation path of the stator coil is usually through the motor stator core to transfer heat to the motor shell to realize the heat dissipation of the stator coil. The existence of gaps will reduce the heat conduction efficiency, and the heat conduction path will be too long to limit the heat conduction efficiency, which will greatly affect the heat dissipation effect, thus limiting the maximum output power of the motor and affecting the improvement of the power density of the motor. In addition, because the coil is wound There will be gaps more or less, making the coils loose, and the stator coils will vibrate during the operation of the motor, which increases the noise of the motor.
