摘要： A motor including a housing, a stator assembly, a rotor assembly, a controller, and a top end cover. The housing includes a cavity. The stator assembly includes a stator core and a stator winding and is housed in the cavity. The top end cover is disposed on the top of the housing. The rotor assembly includes a permanent magnet, a revolving shaft, and a rotor support. A bearing support extends inward from the center of a top end face of the top end cover, with a bearing chamber respectively provided on both ends thereof. The revolving shaft is disposed into and supports the bearing. A connection kit extends from the edge of the rotor support and outside the bearing support. The permanent magnet is disposed on the connection kit. The motor is characterized by simple and compact structure, lower cost, easy thermal dissipation, smaller axial dimension, and convenient assembly.

摘要： Taught herein is a controller for a DC brushless motor comprising a control board (3) and a housing (4); wherein the control board (3) is disposed in the housing (4), and the housing (4) is made of metal materials with good thermal conductivity; a plurality of heat sinks (5) are disposed at the bottom of the housing (4), thereby heat generated by the control board (3) will be dissipated fast, and the operating temperature and failure rates are reduced; an integrated power module chip (7) disposed at the bottom of the control board (3) transfers heat to the housing (4) via an insulating heat sink (8), and in doing so prevents electric leakage; the purpose of a plurality of gaps (9) disposed at the top of the housing (4) is to provide ventilation, and to dissipate heat fast; all of these design characteristics make the invention simple in structure, and convenient for mass assembly.
摘要翻译：这里描述的是一种用于直流无刷电动机的控制器，其包括控制板（3）和壳体（4）; 其中所述控制板（3）设置在所述壳体（4）中，并且所述壳体（4）由具有良好导热性的金属材料制成; 多个散热器（5）设置在壳体（4）的底部，由此由控制板（3）产生的热量将被快速消散，并且降低了工作温度和故障率; 设置在控制板（3）的底部的集成电源模块芯片（7）通过绝缘散热器（8）将热量传递到壳体（4），从而防止漏电; 设置在壳体（4）的顶部的多个间隙（9）的目的是提供通风并快速散热; 所有这些设计特点使得本发明结构简单，便于组装。
