About the selection of gear motors

1: Mechanical size
1: The maximum acceptable installation space, such as diameter, length, etc.
2: The size and installation position of the screws, such as the specifications of the screws, effective depth, spacing, etc.
3: The diameter of the product output shaft, the size of the flat screws, the pin holes, the positioning baffles, etc., this first considers the installation matching. In product design, try to reserve a larger product assembly space, so that there are more models to choose from.

2: Selection of electrical performance
1: Determine the rated torque and speed. If you don't know what you need, you can buy a ready-made one on the market after estimation and go back to test it. After OK, send it to the supplier to help test and confirm. At this time, you only need to give the power-on voltage and working current.
2: Maximum allowable current and torque. Generally speaking, everyone thinks that the greater the torque, the better. In fact, excessive torque will damage the entire equipment system, cause mechanical and structural wear, and cause damage to the motor and gearbox itself and insufficient life.
3: When selecting electrical performance, try to use low speed and small reduction ratio, so that you can get a high-strength and long-life product.

3: Noise selection Usually, the noise refers to mechanical noise
1: After the motor is installed in the product, it is found that the sound is relatively loud and the noise needs to be improved. Repeated sample delivery still cannot solve the problem, and this situation often occurs. In fact, this noise may not necessarily be the noise emitted by the product itself, but may be caused by a variety of noises, such as resonance caused by too fast rotation speed, resonance formed by direct rigid cooperation between the reducer and the mechanical equipment, and noise caused by the eccentricity of the drag load.
2: In addition, the selection of the product itself also requires strong technical support. Usually, the noise of plastic gears is lower than that of metal gears, the noise of helical gears is lower than that of spur gears, and the noise of metal worm gear structures and planetary gearboxes is greater. Of course, noise can also be effectively reduced by optimizing the design and ensuring processing accuracy.
Four: Determine the priority direction of product guarantee
1: Select different reduction motors according to different use environments. For example, financial machinery requires product reliability, toys require product safety and environmental protection, industrial products such as valves need to give priority to product life, and household products should give priority to product silence, etc.
2: Usually, experienced engineers will tailor detailed products to meet the requirements of different customers, and will not be limited to satisfying the speed and torque of the product. As the uses of products vary greatly, the selection of reduction motors is a science, and it is difficult to achieve professional level in a short time. In this case, it is best to entrust professional engineers to help with the selection, which can achieve twice the result with half the effort.
