How To Replace The Damaged Motor Of The Parking Space Gate Motor

How to achieve forward and reverse rotation of the brake motor?
To achieve forward and reverse control of the gate motor, we can adjust the phase sequence of any two phases in its power supply (we call it commutation). Usually, the V phase remains unchanged, and the U phase is adjusted relative to the W. In order to ensure that the phase sequence of the motor can be reliably switched when the two contactors act, the wiring should be consistent at the upper end of the contactor, and the phase should be adjusted at the lower end of the contactor.

 

Is the gate motor DC or AC?
The gate motor is usually a DC motor. The gate motor needs to have characteristics such as high torque, fast start stop, reliability, and controllability, and the DC motor precisely meets these requirements.

 

DC motors are more flexible in control, and can control the opening and closing of the gate by adjusting the current size and direction.

In addition, DC motors also have the advantages of high efficiency and long lifespan, which can adapt to the needs of long-term operation. Therefore, the gate motor is usually driven by a DC motor.

 

Is the gate motor buzzing and unable to lift the pole?
The screw of the active joint of the gate is loose

The movable joint screws are connected by positive and negative threads, and the upper and lower bearings are connected by double headed screws. If the screws are loose, it will result in inaccurate positioning of both the upper and lower positions. The repair method is to use an 80 millimeter long iron rod with a diameter of 4, insert it into the double headed screw and rotate it, then adjust the gate rod up and down to position.

 

Power outage maintenance switch power outage

When the control of the gate malfunctions, the automatic maintenance equipment of the gate will work automatically. At this point, the brake lever stops in an inclined upward position and the machine does not work when the main power is disconnected. The repair method is to open the machine door at this time, rotate the large belt clockwise for 3-8 turns, and when it reaches the upper position, it can be restored. If the state cannot be restored after so many times, it is necessary to check whether the Hall element and circuit board are malfunctioning.

 

Loose buried wires in the coil of the barrier gate

When the ground sensing coil cannot be stably fixed inside the nest, the roar of the car pressing over the road can cause deformation of the coil inside the nest and change the initial inductance of the ground sensing. At this time, it is necessary to reset the sensor from the beginning before it can operate normally. Repair method: Pour melted asphalt into the interior to fix it.

 

The screw of the lever arm of the barrier gate is loose

If this screw is loose, the upper and lower positions of the gate rod that makes up the barrier gate will be inaccurate, and there will be significant shaking when stopping the rod. Repair method: Hang the bolt and lock the nut tightly.

 

Control the magnet movement in place

Cimin Hall elements are used for both up and down positioning. If the orientation of the rectangular magnet and the circular disc with cam in the reducer is changed, it will result in inaccurate positioning. The repair method is to adjust it accurately without flipping it over, and the problem can be solved.

 

What is the reason for the inability of the gate motor?
Firstly, when there is a problem with the gate machine, friends can adjust the limit position. When they find that the gate rod of the gate machine is not in a horizontal position, they can adjust the limit position of the magnet. The correct way is to adjust the magnetic poles. In an incorrect state, LED lights will flash abnormally. The simplest method is to adjust the magnetic poles to ensure that the horizontal and vertical positions are guaranteed.

Secondly, it is necessary to adjust the balance of the gate machine, because the gate machine mainly relies on precise balance to control the tension of the spring, ensuring that the gate machine rotates manually in the event of power failure, and further testing the tension state of the spring.

Thirdly, the fuse of the gate machine is also prone to problems, and it needs to be replaced when it is found that the fuse is blown

 

How to distinguish the model of the gate chip?
Open the gate to find the motherboard, locate the chip on the motherboard, and if there is a silk screen on the chip, you can check the chip model.

At present, there are two main types of remote controllers for road gates: solder codes and learning codes; After confirming clearly.

1. If it is a soldering code, please first solder the code inside the new remote control to the same code as the old remote control (it needs to be disassembled to see).

2. If it is a learning code, you can set it yourself after selling the remote control. The method is as follows: there is a "learning key button" in the main control board of the barrier gate. Press the indicator light next to it and it will light up. At this time, hold the new remote control that needs to be learned and keep pressing it a few times. After the indicator light goes out, use the newly learned remote control to press the up and down keys to see if the gate lever responds. If there is a response, it is already set.
