What Are The Electrical Parameters Of The Miniature DC Motor Of The Beauty Device?

Beauty instrument in matching the micro DC motor, you need to adjust each electrical parameters, so beauty instrument need to match which micro DC motor electrical parameters? Today, we will introduce the parameters that need to be noted when selecting the micro DC motor for beauty instrument
1. micro rated motor voltage
The rated parameters of all beauty instrument miniature DC motors are tested using their rated voltages, which are generally around 3.7V. When operating a beauty instrument miniature motor, the rated voltage should not be exceeded because doing so will shorten the life of the motor. When the beauty instrument motor is operated at a higher voltage than recommended, combustion will occur.
2. The rated speed of the beauty instrument motor
Refers to the speed of the beauty instrument motor in terms of rated motor and torque in rpm, which is the number of revolutions of the micro motor in a minute, and the choice of beauty instrument motor should be adjusted according to the performance of the product to adjust the speed.

3. the rated torque of the beauty instrument motor
Can use the formula T (torque) = 9550 × P (power) ÷ n (speed) to calculate the torque of the micro-motor at rated voltage and speed (rpm)
4. Rated current
Although the current of a typical beauty appliance micro motor is quite low, the windings of the beauty appliance motor can reach the maximum allowable temperature at the rated voltage, speed and torque.
5. No-load and loading speed
Loaded is the speed of a beauty instrument micromotor with a load at rated voltage. Loaded speed will be lower than no-load speed, while no-load is the speed of a beauty instrument micromotor without a load (i.e. with any object on the output shaft) at rated voltage.

6. Blocking current and no-load current
Brushed micromotor is more used in beauty instrument micromotor, and its no-load current is a comprehensive index, which depends on the size of commutator and the friction of brushes.
7. Blocking torque
The rise in winding temperature of the micromotor causes a decrease in blocking torque, which is necessary to achieve the overload capability of the micromotor in beauty instrument motors.
8. Maximum efficiency and speed
Micromotors work with power losses; for most beauty tools, the efficiency is between 78% and 85%, but for hollow cups, it can reach more than 90%. And the maximum speed is the maximum speed at which the beauty tool motor can operate, taking into account temperature variations and other factors; operating above this speed will shorten the life of the motor.

The above is the beauty instrument motor selection parameters to pay attention to, I hope you have a reference, more related information welcome to consult us at any time
