What data needs to be measured to produce micro motors?

The performance of a micro DC motor is affected by a number of characteristics, and these parameters are typically developed and tailored in accordance with the needs of the product. So, what criteria will be examined when the tiny DC motor leaves the factory? I'll introduce myself below.

1. Measuring the torque and speed of a DC motor

Static and dynamic torque, including motion torque, continuous torque, pulsing torque, and other types, are the two categories into which the micro DC motor's torque is separated. Numerous micro DC performance factors, including noise, service life, torque, and others are influenced by the speed of spin.

2. Power estimation

Test the voltage and current numbers as well as the micro DC motor's power at the recommended voltage and speed.

3. Performance test

The ratio of the micromotor's active input power to its active output power is referred to as its efficiency. Iron loss and copper loss make up the majority of the factors influencing the micro DC motor's efficiency.

4. Test for temperature rise

For the micro motor to operate normally, the temperature of each component of the micro DC motor is crucial. The service life of the micro motor will be limited or the micro motor will be burned unless the rotor is locked or the continuous ultra-high voltage operation causes the temperature to be too high. standard tests Infrared testing is the technique.

5. Sound Test

Products utilized in low-noise conditions, such as medical equipment, home beauty tools, personal care items, etc., must undergo noise testing. Speed, lubrication, and the material of the micro motor are some of the factors that influence the loudness of the micro DC motor.

6. Service life evaluation

The service life of thousands of hours is one need for this test, which calls for continuous operation at the rated voltage and speed until the micro DC motor can no longer rotate. Longer lasting, noisier, and shorter brushes are carbon brushes (low noise).
