Abstract

The invention discloses electrically driven equipment with control function of a brushless direct current motor. The electrically driven equipment comprises the brushless direct current motor, a power wire and an input control signal socket, and is characterized in that: a motor stator component, a motor rotor component, a controller power output component, a main control board, a motor front end cover, a motor rear end cover, a motor position sensor signal wire, a connecting cable, a motor input phase wire and a rear cover board are arranged in a shell component of the brushless direct current motor, wherein the motor stator component is arranged in the shell component in a press fit method; the motor rotor component is arranged on the motor front end cover and the motor rear end cover through a bearing; the controller power output component and the main control board are arranged on the motor rear end cover; the power wire is arranged on the main control board through the rear cover board; and the input control signal socket is arranged on the rear cover board. The electrically driven equipment of the brushless motor has a simple structure, small volume, small electromagnetic interference and low cost, is convenient to use and reliable to control.

Description

Technical field [0001] The invention belongs to electric drive and control equipment in the electromechanical field, and in particular relates to an electric drive equipment of a brushless DC motor with a control function. Background technique [0002] Due to its high efficiency, especially its speed regulation characteristics and simple speed regulation method, brushless DC motors are now more and more widely used in various fields as an energy-saving and environmentally friendly electric drive equipment. The normal operation of the brushless DC motor requires a controller composed of electronic devices to complete the high and low speed control, the change of forward and reverse directions, and the monitoring and adjustment of various parameters when the motor is running. Therefore, the brushless DC motor must be used in conjunction with its corresponding controller. The brushless DC motors and controllers used in the current market are two independent products, which ar...
