How to conduct data communication on the weak wire

If you want to use the existing wire lines in the room for network communication, you will generally use the power line carrier method to carry out data transmission on the strong wire lines. Now I have come up with a simpler, cheaper and more reliable method, as long as a few discrete devices and two ICs communicate via weak current circuits (such as telephone lines).

The transmission rate of this circuit can reach at least 32kbit / s. If the carrier is higher, the speed can be faster. For simplicity, the key switch we use has no noise reduction function and can be implemented in software if desired. U1 is a PIC microcontroller, equipped with several peripheral devices and a PWM module.

It should be noted that this circuit can only be used in a low-voltage weak current environment, and cannot be connected to high voltage.

Permanent magnet Dc Motor is composed of stator magnetic pole, rotor, brush, case and so on. Stator magnetic pole is made of permanent magnet (permanent magnet steel), ferrite, alnico, ndfeb and other materials, and the rotor is generally made of silicon steel laminated. Enameled wire is wound between two slots in the rotor core (three slots are provided with three windings), and its joints are separately welded on the metal sheet of the commutator. Electric brush is a conductive part connecting power supply and rotor winding. Permanent magnet motor brush USES single metal sheet or metallic graphite brush, electrochemical graphite brush.Permanent Magnet Gear Motor is established using permanent magnet magnetic field of a dc motor. Permanent magnet Gear Motor is widely used in various kinds of portable electronic equipment or apparatus

Features: usually used financial equipment, office equipment, electronic locks, wireless charger, remote control toys,

precision instruments and meters,automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows,etc., wide application range,,Permanent Magnet  Gear Motor is usually used in small power occasion.

Features: permanent magnet gear motor is a kind of rectangular pulse wave, sine wave current, in the form of hybrid permanent magnet motor. Simple structure, high reliability and high efficiency.

 

Method of use: the best stable in horizontal plane, installed on the permanent magnet gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the permanent magnet gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.

 

Operating temperature range:

permanent magnet gear motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at  ordinary room temperature catalog specifications re based on use at ordinary room temperature  (approximately20~25℃.

If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.

 

Storage temperature range:

permanent magnet gear motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.

 

Service life:

The longevity of permanent magnet gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.

 

when it come to volume production,we're a major player as well .each month,we rurn out  600000 units,all of which are compliant  with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department  to service to you Looking forward to your inquiry.
