The reduction ratio of a reduction motor refers to the rotation speed ratio between the reduction device (such as planetary gear, worm gear, cylindrical gear, etc.) and the rotor on the motor output shaft (usually the rotor on the motor). The reduction ratio can be calculated by the following formula: Reduction ratio = output shaft speed/input shaft speed. Among them, the output shaft speed refers to the output shaft speed after the speed of the reduction device is reduced, and the input shaft speed refers to the speed of the motor itself.

The reduction ratio is used to describe the speed change of the reduction device to the motor output. Since motors generally output at higher speeds, in some applications lower speeds are required to meet demand. At this time, the reduction motor comes into play, reducing the speed of the output shaft through the reduction device to provide the appropriate rotational speed. On the one hand, the selection of the reduction ratio needs to be based on the requirements of the actual application, and on the other hand, the design and manufacturing costs of the reduction motor need to be considered. Usually, the reduction ratio of the reduction motor can be determined based on the ratio of the required speed and torque. If the output of high torque and low speed is required, the reduction ratio needs to be larger; and if the output of high speed and low torque is required, the reduction ratio can be relatively small. The selection of the reduction ratio should also consider the impact on the overall performance of the reduction motor. The larger the reduction ratio, the overall size and weight will usually increase, and it may also have a certain impact on the efficiency of the geared motor. Therefore, factors such as power requirements, size constraints, weight requirements, and efficiency need to be considered when selecting a reduction ratio.

The reduction ratio of the reduction motor is generally determined by the gear ratio of the gear or worm inside the reduction device. For example, if the output shaft of a reduction gear has 10 times more gears than the input shaft, then the reduction ratio is 10. Normally, the reduction ratio is a fixed value, but in some special cases, some reduction motors can also be adjusted as needed to provide different reduction ratios. The selection of the reduction ratio is of great significance to the application field of reduction motors. Reduced motors are widely used in various mechanical equipment, such as machine tools, conveyors, printing machines, wind turbines, etc. Different application fields have different requirements for reduction ratios. Some applications require a larger reduction ratio to provide more torque, while some applications require a smaller reduction ratio to provide higher speeds.

In addition to the reduction ratio, the reduction motor also has some other important performance parameters, such as rated speed, rated power, rated torque, etc. These parameters also need to be considered comprehensively when selecting a reduction motor. Only by fully understanding and rationally selecting the reduction ratio and other performance parameters can we ensure that the reduction motor can work normally under specific application conditions and meet the needs of users. In short, the reduction ratio of the reduction motor refers to the rotation speed ratio between the reduction device and the rotor on the motor output shaft. The selection of the reduction ratio needs to be comprehensively considered based on the application requirements and the impact on the overall performance of the reduction motor. The reduction ratio of a reduction motor is one of the important parameters that affect its output speed and torque and is of great significance to the operation and performance of various mechanical equipment.
