Speedgate is generally used and upgraded!


Dongwo technology brushless motor speed gate has the following advantages:
1. Dongwo Technology brushless motor speed through door speed adjustable range 0-240 equivalent factor, using infinitely variable speed, free setting of driver, control motherboard calibration zero position, easy operation.
2. The torque of the brushless motor of Dongwo Technology is large, 30W, 180N.M or more, which is 1/3 larger than the ordinary brushed motor. Automatically find the zero position, convenient and fast, driving the swing arm fast, open the gate quickly, and reset quickly are the characteristics of the quick-pass door.
3. The brushless motor has its own encoder, which has the effect of the number of energized phases. Under the action of the automatic encoder, it is accurately positioned and automatically braked in place, unlike the brushed motor's inertial effect.
4. The brushless motor reverses the buffer. Suddenly the external force acts on the swing gate swing arm and exceeds the zero position. The brushless motor starts the buffer mode. The buffer force is automatically adjusted according to the external force to eliminate the external force from moving closer to the middle zero position. The gate will continue to alarm until the normal alarm is released.
5. The brushless motor control motherboard is independently developed by Dongwo Technology Co., Ltd., with independent intellectual property rights, multi-functional industrial-grade motherboard, ARM intelligent control system, high degree of intelligence, each time the door swing angle, speed, passing times, self Inspection mode, etc., LCD screen operation, intuitive and simple, stable and reliable.
6. The main board of the brushless motor control fully detects passing, baggage, passing (bicycle, etc.) and other modes. It has a high safety factor and will not trap defects such as people and vehicles. Illegal intrusion alarms automatically, retrograde intrusion alarms and closed gates, one person and one card continue to pass.
7. The brushless motor control motherboard expands various functions, is compatible with 482 and 232 protocols, and has a development interface for customers to do secondary development, and provides Dongwo Technology's brushless control development kit.

Speed-pass doors are now gradually popularized. Speed-pass doors are upgraded versions of swing gates, which have many functions and many advantages, but Dongwo technology people will not meet the reality, and then upgrade brushless motors on the basis of existing speed-pass doors. In the future, we will also make servo motors and more advanced electronic control equipment.
Let us first understand the brushless motor. The operation principle of the brushless DC motor is basically the same as that of the brushed DC motor, that is, under a magnetic pole with a constant magnetic flux density distribution, the total amount of current flowing into the electric drive winding is guaranteed to generate a constant torque, brushless The operation of the DC motor also depends on the rotor position sensor to detect the rotor position signal, through the commutation drive circuit to drive the power switch connected to the armature winding on and off, thereby controlling the stator winding energization, on the stator Generate a rotating magnetic field and drag the rotor to rotate. As the rotor rotates, the position sensor continuously sends out signals to change the energized state of the armature so that the direction of the current in the conductor under the same magnetic pole remains unchanged. Therefore, it can produce a constant and make the brushless DC motor run much smoother than the brushed motor.
When the brushless motor of the quick-pass door passes through the zero position, the positioning is accurate, there will be no inertia, the brake is accurate, and the speed can be adjusted. The high-end quick-pass door just meets the needs.
1. The speed gate requires a fast opening speed, and now the urban life is fast-paced, and the same is true for pedestrian passage gates. All want to pass the gate faster. The speed of the gate determines the performance of your gate, so choose the fast speed gate. The door appears to be a high-end and stylish gate, and customers will rely on the Sutong door of Dongwo Technology brand when using it.
2. Precise positioning of the speed gate. How fast the car can drive above, otherwise it is not easy to control and easy to collide. Since the speed of the speed gate is fast, it must also be able to control the brake positioning of the brake. The brushless motor itself has a zero position. When the rotor turns At zero position, the sensor signal is cut off, the motor will not work, the braking performance is good, and there will be no inertial overshoot. The disadvantage of the brush motor is that it is easy to overshoot when there is an inertia, resulting in deviation and instability This is a clear advantage of brushless motors.
3. The speed-opening door runs smoothly, and the speed-opening door with a brushless motor rotates very smoothly. As mentioned above, the stator and rotor magnetic fields on the windings run smoothly, and the current will not be very large when starting, and there will be no frustration in place. The brushed motor has the feeling of large starting current, and the operation is not smooth. The high-end speed gate of Dongwo Technology rotates steadily and operates reliably, and the brushless motor products are more upscale.
