The invention discloses a DC brushless motor control system for a treadmill and a treadmill adopting the system, which includes a stator mechanism arranged on the inner wall of the casing. The outer cylinder is sleeved outside the iron core. There are three thread grooves inside the outer cylinder along its axial direction. The three thread grooves are arranged parallel to the radial direction of the outer cylinder. The inner thread groove communicates with the inner wall of the outer cylinder. There are three annular grooves at the bottom of the iron core, and the three annular grooves are respectively connected with the three threaded grooves. There is a groove in the inner center of the iron core, and a vertical chute connected with the groove is also opened inside the iron core. , the vertical chute extends outward along the radial direction of the iron core and communicates with the inner wall of the outer cylinder. In the present invention, the rotation of the outer cylinder relative to the iron core drives the stator winding to switch between the threaded groove and the annular groove, so as to change the density of the turns of the stator winding, thereby achieving the purpose of adjusting the motor speed.
Description
technical field [0001] The invention relates to the technical field of motor control, in particular to a DC brushless motor control system for a treadmill and a treadmill using the system. Background technique [0002] The speed control of the DC brushless motor is generally through setting the speed inside the brushless motor controller, but usually only one speed is set, but the treadmill needs to set a variety of different speeds for the motor to meet people's fitness needs. need. Obviously existing DC brushless motors cannot be directly applied to treadmills. In the prior art, a patent document with the application number 200610036508.2 titled a speed control system for a brushless DC motor is disclosed, which provides a speed control system for a brushless DC motor with speed setting and selection functions. However, it uses a specially designed speed circuit, uses the dial of the speed setting circuit to input different signals to the microprocessor, and the micropro...
