Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor control, and particularly relates to a sensor-based BLDC motor controller. Background Art
[0002] A BLDC motor controller is an electronic device used to control the operation of a brushless DC motor. This controller electronically adjusts the speed and direction of the motor to ensure its efficient, safe, and reliable operation. The main functions of a BLDC motor controller include: Electronic commutation: The BLDC motor achieves brushless and contactless operation through an electronic commutator, and the controller is responsible for controlling the timing and method of electronic commutation to ensure the correct rotation of the motor rotor. Speed and direction control: By adjusting the current input to the motor, the controller can precisely control the rotational speed and direction of the motor to meet different working requirements. Protection functions: It has protection functions such as overcurrent, overvoltage, and undervoltage to ensure that the motor can be safely shut down under abnormal conditions and prevent equipment damage or personal injury. Feedback mechanism: Some advanced BLDC motor controllers also use Hall effect sensors or back-electromotive force technology to detect the position and speed of the motor rotor, providing closed-loop control to further improve the performance and efficiency of the motor. Compared with traditional brushed DC motors, brushless DC motors have advantages such as higher energy efficiency, longer service life, smaller size, and lighter weight, so they are widely used in many applications. The BLDC motor controller is one of the key technologies to achieve these advantages. The controller generates a rotating magnetic field by sequentially energizing the stator windings to drive the rotor to continuously rotate, realizing the conversion from electrical energy to mechanical energy. A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric driving torque. Motors are divided into DC motors and AC motors according to the type of power supply used. Most motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. A motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying wire in a magnetic field is related to the direction of the current and the direction of the magnetic induction lines. The working principle of a motor is the force exerted by a magnetic field on a current, which causes the motor to rotate. With the development of society, when a motor needs to be controlled, a sensor-based controller is used.
[0003] When a worker needs to control the motor, the controller is adjusted so that the controller controls the operating state of the motor. However, during the use of the controller, it will be affected by the current, and the current will cause the components on the surface of the controller to overheat, resulting in the controller getting stuck during use, and further leading to a problem of a decline in the use performance of the controller.
