How To Adjust The Speed Of The Beauty Machine Coreless Motor?

DC motor is the core component of beauty instrument, beauty instrument vibration, rotation are relying on dc motor, beauty instrument dc motor vibration, deceleration motor, drive motor, drive motor or coreless motor (no core motor), etc., the speed of the motor and beauty instrument massage strength, suction, coreless motor is a high performance, high efficiency motor, it adopts the magnet closed technology and permanent magnet device, with compact structure, high power density, rapid response, widely used in various industrial fields. One of the features is its hollow design, that is, there is a certain space in the middle, making the motor more portable, easy to layout and installation. At the same time, it also has high efficiency and power density, which can achieve greater output power in a relatively small volume, saving space and energy. Compared with the traditional motor, with faster response speed and higher control accuracy, it can achieve more accurate and flexible control, so the speed regulation of the beauty motor is very important.

Different from the ordinary drive motor, the main form is the rotor, using the iron core-free rotor. This structure eliminates the power loss caused by the vortex formation of the iron core. At the same time, the weight and moment of inertia are also greatly reduced, which reduces the mechanical energy loss of the rotor. Because the beauty instrument uses coreless motor, the rotor structure changes make the great improvement of the running performance of the motor. It not only has the outstanding energy saving characteristics, but also has the control and multimotion characteristics that can not be achieved by the ordinary core motor. How does the coreless motor control the rotation speed? Beauty instrument motor speed regulation is mainly based on the linear relationship of DC motor speed and voltage and load, the main speed regulation mode can be roughly divided into two kinds.

1. No-load speed regulation is related to the voltage, and controlling the coreless voltage size of the beauty instrument is the reason to realize the no-load speed of the coreless motor;

2. Load speed regulation, related to the load, through the controller to receive the motor connected encoder feedback signal, through a certain calculation, control and adjust the loading voltage of the coreless motor or duty cycle to perform speed regulation.
