What does it mean that the controller has 9 tubes and 12 tubes?

9 tubes means that there are 9 MOS tubes inside the controller.

12 tubes have 12 MOS tubes.

Controller (English name: controller) refers to the main command device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in a predetermined order. by program counters.

Composed of instruction registers, instruction decoders, timing generators and operation controllers, it is the "decision-making body" that issues commands, that is, completes coordination and directs the entire computer system.

of the operation. Main classifications:

The controller is a combination of logic controller and microprogram controller, and both controllers have their own advantages and disadvantages. The combinatorial logic controller is cumbersome to design, complex in structure, and once the design is complete, it can no longer be modified or expanded, but it is fast. The microprogram controller is convenient in design, simple in structure, easy to modify or expand, and only needs to reprogram the corresponding microprogram to modify the function of a machine instruction; To add a machine instruction, simply add a microprogram to the control memory, however, it is by executing a microprogram.

The specific comparison is as follows: The combined logic controller, also known as the hard-wired controller, consists of a logic circuit.

composition, relying entirely on hardware to realize the function of instructions.

How it works. Electromagnetic chuck controller: AC voltage 380V is stepped-down by the transformer and then passed through the rectifier.

After the rectification becomes 110V DC, it enters the suction cup through the control device, and the suction cup is magnetized at this time, and the reverse voltage line is passed into the demagnetization process, and the controller achieves the demagnetization function.

Access Controller: The access controller works in two modes. One is the inspection mode, and the other is the recognition mode. In patrol mode, the controller continuously sends the card reader to the card.

Send a query** and receive a reply command from the card reader. This pattern is maintained until the card reader senses the card.

When the card reader senses the card, the card reader produces different replies to the inspection command of the controller, and in this reply command, the card reader transmits the read proximity card internal code data to the access control controller, so that the access control controller enters the recognition mode. In the recognition mode of the access controller, the access controller analyzes the internal code of the induction card, compares it with the card data stored in the device, and implements follow-up actions. After the access controller completes the action of receiving data, it will send a command to reply to the card reader, so that the card reader can restore the state, and at the same time, the access control controller will return to the inspection mode.

The strength of the 9 tube is a little less than that of the 12 tube.

9 tubes means that there are 9 MOS tubes inside the controller. There are 12 of 12 tubes.

It's just that the power increases, and the speed does not become faster.

The only way to speed up is to change to a higher speed motor.

Under the same power splitter, the more tubes, the more powerful the performance, and the lower the calorific value, but if the power of a single tube is large, the combined 9-tube controller is better than the 12-tube with a single tube, depending on the quality of the individual tubes.

The electric vehicle controller is used to control the start, run, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor core control device, it is like the brain of the electric vehicle, is an important component of the electric vehicle. At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc., and electric vehicle controllers also have different performance and characteristics because of different models.

The controller is the number of transistors in the controller, and the common ones are generally 6 tubes, 9 tubes, 12 tubes, 15 tubes, and so on.

The more tubes, the greater the power output, [the greater the power], but the power consumption will be faster, generally 400w below 6 tubes, 800w is 9 tubes, 1000w is 12 tubes, 1500w is 15 tubes.

Electric Vehicle Controller:

The electric vehicle controller should be a comprehensive design that takes into account the actual use of the battery and the motor, and the relationship between the battery, the controller and the motor should be fully considered, and they should be designed as a comprehensive system, so as to obtain a more ideal electric vehicle controller.

It should not be commercially available, as long as it has stepless speed regulation, brake power-off, soft start ......and other functions of the electric vehicle governor. According to the actual use of electric bicycles, the design of the brushless electric bicycle controller was improved, and the short-circuit protection function of the output of the electric vehicle controller was added.

This controller can realize direct short-circuit protection at the output end, even when the motor is operating at the highest speed (at this time, the highest voltage is often output) directly short-circuit the output of the controller, the controller can also be very reliable protection. <>

The 9-tube controller is an electronic device that is commonly used to amplify and control signals and Woo Kai Liang currents. It consists of 9 connected tubes, including two transistors and seven diodes.

When observing the 9-tube controller, you can first check whether its overall structure is intact: no damage, poor contact and loosening.

After inspecting the intact structure, the state of each tube on the controller can be observed separately to determine if it is working properly. Generally speaking, when the 9-tube controller is working normally, the state of each tube should be stable. This can be done in the following ways:

1.Use a multimeter or oscilloscope to test the voltage, current, and waveform of each tube to make sure the pipeline is working properly.

2.Observe the appearance of each tube and check for damage or deformation.

3.The entire circuit is tested using test equipment to ensure that the controller as a whole is working properly.

It should be noted that the 9-tube controller must pay attention to safety when using, and do not directly touch the lines and components to avoid electric shock and other safety problems. If you are not familiar with circuit maintenance, it is recommended to find a professional to operate and inspect it.

The difference between the 12-tube and 15-tube controllers of the electric vehicle controller is that the current limiting is different, the torque is different, and the power is different.

1. The current limit is different.

The 12 tubes are generally limited to 28-30A, and the 15 pipes are generally limited to 33-35A.

2. The torque is different.

The strength of 12 tubes is a little smaller than that of 15 tubes, and the strength of 15 tubes is a little greater than that of 12 tubes.

3. The power is different.

The 12-tube controller is equipped with a 500W motor, and the 15-tube controller is equipped with a 650W motor. The diameter of the five thick wires of the two is also different, the general wire diameter of 12 pipes is, and the general wire diameter of 15 pipes is.

Precautions for wiring of electric vehicle controllers:

First of all, it is necessary to ensure that the positive and negative poles of the power supply must be connected correctly, otherwise the controller will be damaged.

Find the connector connected to the controller and the handlebar. If the plug-in on the controller is not matched with the contact on the handlebar, the plug-in can be removed in order to dismantle the brother in case of emergency, and the wire is directly connected between the wires. At this time, don't be afraid of trouble, be sure to connect the street firmly, if possible, it is best to weld the street firmly with an electric soldering iron, and then wrap it with insulating tape to avoid hidden dangers in the future use process.

Pay attention to the positive and negative poles of the connection between the controller and the motor. If it is found that the motor is reversed, the positive and negative poles of the motor can be reversed.

Since some controller handlebars have the same cable form as the sensor cable form, and the connector is used the same, it is important to distinguish between the two correctly. <>

Controller: 15 tubes, 18 tubes, refers to the general term for game consoles (such as PlayStation, Xbox, etc.), game controllers with 15 physical buttons and 18 virtual buttons (including joysticks). On the main unit, the 15 physical buttons refer to the real buttons set on the buttons and nodes.

Specific analysis: For example, PS (PlayStation) must be the same as the Xbox series, which has 4 arrow keys, 4 shoulder trigger buttons, 4 joysticks, 1 ** button (also called combination buttons) and 2 main ** keys.

The 18 virtual buttons refer to the shortcut keys in the game, also known as the combine button. They are mainly composed of 4 arrow keys, 4 shoulder trigger buttons, 4 joysticks, and another 6 intermediate buttons (which can be supported by 2 function buttons per game console, and up to 4 function buttons).

These keys are used to grasp the game controls and control the choices and movements of the game character, such as fighting, jumping, etc. The game's graphics, game sounds, and various functions can all be controlled through this 15-tube 18-tube game controller.

A game controller is a device designed for gamers and is an important tool for gamers to grasp the gameplay of sports games. Game controllers not only allow players to have more grip on the game, but also better control the movements and directions of the game characters, allowing players to experience the game more immersively and realistically. <>
