How to install a hollow cup geared motor?

The hollow cup motor belongs to the servo motor category. The designer mainly values ​​its response time, so that it can stop immediately and let it turn. It can be turned immediately. How do we install the hollow cup geared motor?

How to install a hollow cup geared motor:

1. The control module that supplies power to the motor should consider the output impedance as small as possible to prevent the output voltage from drastically decreasing during load and affect the vibration.
2. When the motor is working under its nominal rated voltage, the overall performance is excellent. It is recommended that the working voltage of the mobile phone circuit be designed as close as possible to the rated voltage.
3. Avoid close to the strong magnetic area during transit or use, otherwise it may cause the magnetic steel of the motor to twist and affect the performance.

Method of installing a hollow cup geared motor

1. Pay attention to soldering temperature and soldering time when soldering. It is recommended to use 320 °C for 1-2 seconds. If the time is too long and the temperature is too high, the lead insulation may be damaged.
2. When the column motor is inspected or tested for stall current, the stall time should not be too long (less than 5 seconds), because all input power is converted into heat energy (P=I2R) when the rotor is blocked, and the time may be too long. The coil temperature rise is high and deformed, which affects performance.
3. When the motor with mounting bracket is designed to position the card slot, the gap with the phone case should not be too large. Otherwise, additional vibration (mechanical noise) may occur. The rubber cover can effectively prevent mechanical noise, but should pay attention to the case. The positioning groove and the rubber sleeve should be interference fit, otherwise the vibration output of the motor will be affected and the vibration sensitivity will decrease.
4. Remove the motor from the package or avoid pulling the lead during the welding process. It is also not allowed to bend the lead at many angles, otherwise the lead may be damaged.

The method of installing the hollow cup geared motor is introduced to everyone here, but Xiaobian recommends that non-professionals try not to operate by themselves, and professional personnel will be better.
