Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an integrated motor. Background Technology

[0002] A height-adjustable desk is a modern office furniture piece that uses a motor to adjust the desktop height, meeting the needs of different users who wish to work standing or sitting. For ease of operation, height-adjustable desks are typically equipped with a hand controller, which acts as a communication bridge between the user and the motor. Through buttons or a touchscreen on the controller, users can easily control the motor's movement, thus controlling the desk's height. The market offers a wide variety of motor models and specifications for height-adjustable desks, ranging from micro motors to high-power motors. Each motor has specific performance parameters and size requirements. However, the motor's control circuit module is generally integrated into the hand controller. Due to the diversity of motor models, the design and manufacturing of the hand controller must also vary to accommodate different motors, resulting in a large number of hand controller specifications and relatively high production costs. Furthermore, to ensure stable and safe motor operation, the motor and hand controller need to be connected via signal and power cables. To maintain a neat and aesthetically pleasing overall layout, these two cables are usually wrapped in the motor's sheath. However, the use of motor sheathing cables also brings additional cost burdens. Worse still, if the motor fails or is damaged, the control circuit module on the matching hand controller often needs to be replaced as well. This undoubtedly increases the user's maintenance costs and inconvenience. Therefore, it is necessary to improve this. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an integrated motor with a simple and reasonable structure and convenient operation. By integrating the control circuit module onto the motor, the versatility of the hand controller is significantly improved. When the motor malfunctions or is damaged, the entire motor can be replaced, greatly simplifying the maintenance process and reducing maintenance costs. Only a signal line needs to be connected between the hand controller and the motor, eliminating the need for additional motor sheathing wires, further reducing costs.
