Description

Technical Field

[0001] The invention relates to a wire protection cover component with a built-in Bluetooth module, a BLDC motor controller, and a motor. Background Art

[0002] Currently, many motors, such as BLDC motors, PMSM motors, and switched reluctance motors, are equipped with motor controllers. These controllers typically incorporate microprocessors with digital processing capabilities. We refer to these motors (DM motors, or digital motors) for short. These DM motors are widely used across various industries due to their energy efficiency, ease of control, and high control precision. They come in a wide variety of types and from a wide range of manufacturers, with many varying control parameters. Even the same manufacturer may offer hundreds of models with varying control parameters. When an electrical device using these motors fails and requires replacement, maintenance personnel often need to know the motor's operating parameters and then reprogram them into the motor controller of the replacement motor. Otherwise, replacement is impossible.

[0003] Regarding the installation of motors in the aftermarket, how to enable maintenance personnel to replace broken motors quickly and easily has become a competitive advantage for motor manufacturers in the aftermarket. Current motor programming systems generally require a laptop and backend support, are bulky, and are very inconvenient to use. Therefore, to address these issues, a motor with a wireless communication device (such as Bluetooth, Wi-Fi, NFC, etc.) has been invented on the market. This allows communication with the motor via a mobile phone, and by using the corresponding software, the operating parameters of the old motor can be read. The relevant motor operating parameters can then be reprogrammed into the motor controller of the replacement motor, allowing maintenance personnel to quickly and easily replace broken motors and program the motor controller of the replacement motor quickly and efficiently, greatly improving work efficiency. The programming device is also small and easy to carry. This type of motor has a simple structure and is easy to use, but the current structure of motors with wireless communication devices is to place the wireless communication device on the motor as an independent communication encoder. In order to protect the wireless communication device, a metal shield is installed on the outside of the wireless communication device, which makes the overall size of the motor large and the manufacturing cost high. It also requires a built-in battery, which makes the motor assembly steps cumbersome and the assembly efficiency low. Of course, some people also integrate the wireless communication device directly on the circuit board of the motor controller, which requires changing the circuit design of the circuit board and increasing production costs. Moreover, since the control box of the motor controller itself is a metal structure, it has a shielding effect on the wireless signal, affecting signal transmission and easily leading to program replacement failure.
