Can the speed of the DC geared motor be adjusted?

　　The DC reduction motor, namely the gear reduction motor, is based on the ordinary DC motor, plus a matching gear reduction box.The function of the gear reducer is to provide a lower speed and a larger torque.At the same time, different reduction ratios of the gearbox can provide different speeds and torques.This greatly improves the utilization rate of DC geared motors in the automation industry.So can it be adjusted for speed?Let's take a look together below:
　　1. The speed of the DC geared motor can be adjusted. (If it is not a brushless DC motor), the geared motor can be powered by a voltage-adjustable DC power supply. The speed of the DC geared motor can be adjusted by adjusting the power supply voltage.
　　2. The deceleration and speed regulation of the geared motor are two different things.Speed ​​regulation refers to changing the power supply voltage of the DC motor (or changing the drive circuit parameters of the DC motor) to achieve the purpose of adjusting the speed, and deceleration (in most cases) refers to the installation of a speed reducer with a certain speed ratio on the output shaft of the DC reduction motor Reach deceleration (at the same time increase torque).
　　3. There are two types of DC motor drives: built-in and external. Most of the built-in drive DC gear motors cannot be adjusted in speed. Whether the externally driven DC motor can adjust the speed depends on the structure of the drive.
　　4. DC motors are divided into "brush motors" and "brushless motors". The former can be adjusted by changing the power supply voltage.The voltage of the power supply of the latter should be constant (the brushless DC motor cannot be adjusted by changing the power supply voltage), but the adjustment purpose is achieved by adjusting the drive.
　　5. DC geared motors with magnets (mostly) are brushed motors.If the rated working voltage of the motor is 12V, a 0-12V DC stabilized power supply can be used to steplessly adjust the speed of the motor.
　　The DC geared motor can realize speed regulation. In the future operation and use, everyone must fully understand the knowledge of the product in order to better apply the equipment.
