Brushless motor internal structure diagram The following is the schematic diagram of the principle and control of the previous stage (electric vehicle) DC brushless motor. In this issue, the operating principle of the brushless motor is emphasized. The positive power line of the internal Hall sensor of the motor, that is, the red line is generally connected to 5-12v DC. And mostly 5V. Hall's signal line transmits the position of the magnet inside the motor relative to the coil. According to the signal controller of the three Halls, it can be known how to supply the coil of the motor at this time. (Different Hall signals should provide corresponding to the motor coil. The current in the direction) means that the Hall state is different and the current direction of the coil is different. Second, the operating principle of the brushless motor Hall signal is transmitted to the controller, the controller supplies power to the motor coil through the motor phase line (thick line, not Hall line), the motor rotates, the magnetic steel and the coil (accurately wrapped around The coil on the stator, in fact, the Hall is generally mounted on the stator. The rotation occurs, the Hall induces a new position signal, and the thick line of the controller supplies the motor coil to change the current direction again. The motor continues to rotate (the position of the coil and the magnet) When a change occurs, the coil must change the current direction correspondingly so that the motor can continue to move in one direction, otherwise the motor will swing around at a certain position instead of continuously rotating. This is electronic commutation. as the picture shows

Gear Reducer Motor is a small precision reducer, and the size and specification can be customized below 38mm. Shenzhen shun cheong electrical co., LTD. 15 years engaged in the design, development, manufacture Dc Gear Motor, products applicable to the smart home, widely used in intelligent robot voice interaction, children's education escort robot, intelligent sweeping machine robot, intelligent robot adaptability, independent motor, intelligent medical robot project.
Application field:
Method of use: the best stable in horizontal plane, installed on the gear reducer motor output shaft parts, cannot use a hammer to knock,knock prone to press into the gear reducer motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Gear reducer 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:
Gear reducer 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 gear reducer 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.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—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.
