FrançaisWith the rise of markets such as Industry 4.0, UAVs, Intelligent Robots, and New Energy Vehicles, the market potential in the field of drive and control will gradually be released, and the market size of motor controllers will gradually increase. The importance of motors has once again caused people's attention.
The micro-motor is essentially a DC electric motor. After power-on, the speed is usually very high, at least several hundred rpm, and the higher point can reach tens of thousands of revolutions. In this case, the torque of the motor is small and cannot be driven heavy. s things. However, due to the low speed and large torque of the micro-motor, this point cannot be replaced by the AC motor, so that we can adjust the speed of the micro-motor through the gear.
The introduction of the geared motor, that is, the gear DC geared motor, is based on the usual DC geared motor, plus the matching gear reducer. The role of the gear reducer is to supply a lower speed and a larger torque. Different gear ratios of the gearbox can supply different speeds and torques. This greatly improves the use of DC geared motors in the automation profession.
In the case of the same power, the faster the speed, the smaller the torque (commonly speaking, the force), and the lower the speed, the greater the torque. The greater the reduction ratio, the greater the torque and the lower the speed.

Define the calculation method: reduction ratio = input speed ÷ output speed.
Second, what should you pay attention to when purchasing miniature geared motors?
The choice of the micro geared motor first considers that the output speed (speed) is consistent with the requirements of use, then the output torque meets the requirements for use, and then the operating voltage is considered. Dimensions, mounting structure, working conditions, etc.
1. Determine what equipment the geared motor is used to determine the safety factor and installation form of the motor;
2. Determine the torque and speed of the dragged working machine, and calculate the power of the motor based on these two parameters;
3. Select the model of the motor according to the working machine torque, the reduction ratio of the reducer, the power, the installation method, etc.
4. Determine the ambient temperature at which the motor operates.
