Introduction of brushless reduction motor scheme for pedestrian barrier gate: Gate is a kind of channel blocking device (channel management equipment), which is used to manage the flow of people and regulate pedestrian access. It is mainly used in Metro gate system and toll gate system. Its most basic and core function is to achieve the goal of only one person at a time, which can be used at the entrance passage of various charging and access control occasions.
Install organic core in pedestrian brake. When pedestrians pass through the gate, the machine core will rotate at a certain angle to drive the door plate to rotate, so that pedestrians can pass through. The existing machine core is mostly split type, which has poor stability and is easy to damage.
The intelligent reader feeds back the information to the
pedestrian barrier gate, and then transmits it to the brushless motor through the single chip computer. How to choose the brushless deceleration motor to receive the information of the single chip computer?
1.Choose from the speed. Speed: 20-30 person/minute, opening and closing time: 1 second. The brushless motor with reducer is selected, the speed is about 250-300 rpm/min.
2.Select from the moment. Brushless speed reducer mainly drives the telescopic arm of pedestrian barrier gate. When choosing a motor, many people feel that the greater the torque, the better. But the bigger the torque is, the longer the length of the gearbox will be, and enough reserved space will be needed. But it only drives the telescopic arm. The weight of the telescopic arm is estimated first, and then the buffer force in case of an accident is predicted. If the torque of 20kg/cm meets the requirements, it will not waste resources.
3.Choose from voltage. Brushless speed reduction motor obtains information by connecting with single-chip computer and chooses 24V when choosing voltage. Users need to consider when choosing the type of pedestrian barrier gate brushless deceleration motor: whether the motor needs positive and negative rotation, drive speed regulation scheme, deceleration ratio of decelerator, selection of encoder, etc.
