Embodiment Construction

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a vector control asynchronous motor. The asynchronous motor comprises a housing, a stator, a rotor, and a heat dissipation assembly. The housing comprises a cylinder and a tail cover. The cylinder is provided with a plurality of heat dissipation convex ribs which are bulge outwards. The tail cover covers one end of the cylinder, and the tail cover is provided with a plurality of ventilation holes. The stator is annular, and is fixed at an inner side of the cylinder, and the rotor is inserted in the stator, wherein one end of the rotor extends out of the cylinder in a bulged manner, so as to form an output shaft. The heat dissipation assembly comprises a first fan wheel and a second fan wheel. The vector control asynchronous motor is better in heat dissipation effect.

Description

technical field [0001] The invention relates to a vector control asynchronous motor. Background technique [0002] Motors are used in various industries, for example, motors can be used in motors, computer cases, etc. A general motor is used to drive a fan or a pulley to rotate. The motor includes a stator and a rotor inserted inside the stator. The stator uses electromagnetic induction to drive the rotor to rotate. The motor will generate heat during operation and needs to be dissipated. However, the heat dissipation effect of the general motor is poor. Moreover, the algorithm adopted by some vector control motors is a low-pass filter, which requires the microcontroller to perform repeated calculations in each operation cycle, resulting in excessive operation time of the microcontroller, and may not be able to respond quickly to the real-time state of the motor. , reducing the reliability of the system. The motor is inconvenient to support and adjust the height of the...
