How to strengthen the speed of the motor of a four wheel drive car I don t want to buy another one

Take out the rotor of the motor, remove the metal wire on it, then wrap the thicker metal wire around the rotor in order, and then attach the end to the motor with melted tin. Then remove the magnet inside and replace it with a magnet and a big one!

If you use the original one, you can't increase the number of revolutions, it is recommended to buy an atomic fission motor, although it is more expensive, but it is super easy to use.

If it is a no-load speed, loosen the brush and replace the magnet with a weaker one.

But if it's a load speed, it's better to buy another one, for a person who even how to increase the speed, the motor he changes himself, it is good to be able to turn a few times,

4x4The motor of 250,000 rpm can be said to be very fast, so to describe it, the speed of 250,000 is equivalent to 1,500 kilometers per hour, which is equivalent to the front end of the rocketAcceleration2 times.

The so-called four-wheel drive car is a car with front and rear differential linkage four-wheel drive, because the engine power is transmitted to the four tires, so the four wheels can exert force, and when one of the driving wheels of an ordinary two-wheel drive car slips, the other driving wheels will also lose power.

Advantages and disadvantages of 4WD:

The advantages are simple structure, high stability, and strong and durable.

The disadvantage is that the general driver must stop the car to operate manually, and some operations are more complicated. At the same time, most time-sharing four-wheel drive have differential locks.

The differential lock, when locked, is not conducive to the vehicle turning, so the four-wheel drive system can no longer be used on paved roads. Especially when turning, so usually use two-wheel drive, and use four-wheel drive when getting out of trouble.

Drive form: The so-called drive form refers to the layout of the engine and the number and position of the drive wheels. Generally, passenger cars have two rows of wheels, front and rear, of which the wheels that are directly driven by the engine to rotate and thus push (or pull) the car forward are the driving wheels.

The most basic classification criteria.

According to the number of driving wheels, it can be divided into two categories: two-wheel drive and four-wheel drive.

In the two-wheel drive form, it can be subdivided into front-rear-wheel drive (FR), front-wheel drive (FF), rear-wheel drive (RR), and mid-rear-wheel drive (MR) according to the position of the engine in the vehicle and the position of the driving wheels. At present, two-wheel drive off-road vehicles and sedans are most commonly used in the form of front-wheel drive and rear-wheel drive. For example, the well-known domestic off-road vehicle brand Jiangling Landwind launched the 04** displacement SUV in 2004 to take this form of drive.

The motor of the four-wheel drive vehicle is composed of a metal shell, a high-temperature resistant base, a silicon steel sheet rotor, enameled wire, a commutator, a brush, a magnetic pole stator, and a DC power supply.

How it works: It uses electromagnetic induction. The enameled wire is wound on the rotor according to the fixed winding, and the motor commutator has 3 poles, when the current passes through the 2 poles, the rotor conductor cuts the rotating magnetic field and generates an induced electric potential, under the action of the electric potential, the rotor conductor flows through the current, and the rotor current interacts with the rotating magnetic field and rotates.

The stator is the shell that holds the magnet, and the stronger the magnetic field, the greater the torque of the motor, that is, the greater the rotational force.

I run a model shop, I don't know if this explanation can be explained?

1.string a variable resistor. The miniature, the one with low resistance should be more suitable.

2.Replace or modify the original reducer.

3.Use two small springs to string them at both ends of the drive shaft, and then install the drive wheels, so that the springs can resist the base and wheels, and the friction will be slowed down.

4.Swap the wheels for smaller ones.

2.Your 4WD is powered by direct current, and capacitors shouldn't make much use of them.

Supplement: When you retrofit, you need to consider how much current is required when the motor is turning at full speed with a load. When your battery capacity is not high enough for the motor to run, it will cause a fault similar to what you said.

It is advisable for you to replace the battery with a larger capacity. It is best to have a lithium battery (light weight, large capacity, and long-lasting power supply). There are also a variety of winding methods when winding the motor, the most basic thing is to remember to replace the original single wire on the motor with a double wire, because the thicker metal wire has a large amount of current, and the power will be more sufficient

The longer the wire, the greater the torsion and the slower the speed. Conversely, the shorter the wire, the smaller the torsional force and the faster the speed. Winding is a kind of winding, I was in addition to winding, but also changed magnets, strong magnetism, and more power Supplement:

1. How to increase your speed.

a.Choose a motor with high speed, such as light-speed motor, American leopard, atomic fission, etc., or modify the motor yourself to increase its speed and torque, so as to facilitate the speed of the car in corners and climbs.

b.Reduce the weight of the carOn the premise of not affecting the whole car, as many openings as possible are hollowed out to achieve the purpose of weight reduction. Note: The modified car must weigh at least 90 grams (including battery and motor) and comply with the competition rules.

c.To improve the performance of the wheels, first of all, select the appropriate wheels from the characteristics of the motor, gear ratio and runway configured by the car; Secondly, adjust the concentricity of the wheels and the perpendicularity of the axle, that is, keep the perpendicularity of the axle and the tire; Finally, the wheels are modified or run-in to improve the performance of the car in a straight line.

d.To choose the battery correctly, the speed of the vehicle can be increased with high current. Such as nickel-cadmium and nickel-metal hydride rechargeable batteries.

e.Reduce the resistance of the car, and pay attention to the run-in of the empty car for the assembly of the new car; Lubrication must be done to minimize the frictional resistance of each rotating part; On the wheel, the middle transition gear should also be equipped with ball bearings; It is best to use ball bearing guide wheels for guide wheels to minimize rotational resistance.

2 What is the relationship between motor speed.

Now there are many consumers who think that the no-load speed marked by the motor is equivalent to the vehicle speed, and think that the higher the no-load speed of the motor, the faster the speed must be, which is very wrong, they ignore another very important performance of the motor - torque, that is, the load capacity of the motor, generally speaking, the motor with weak torque should be matched with a large gear ratio and a small diameter wheel; For the same rotor, the stronger the magnetism, the greater the torque of the motor, and the idle speed will be slightly lower, but the speed is not necessarily slow, so the general fans use strong magnets when winding the motor, just to pursue high torque.

3 Essentials for modifying runways to overcome overpasses.

Overpass, as the name suggests, is the runway contains an arch bridge, the car has an arch bridge shape uphill and downhill in the track, the difficulty of the runway is also in this uphill and downhill place, when the speed is too fast, the car will fly out of the runway at the overpass, which is also the highest runway with the highest speed ratio in the previous "Audi Cup" national youth four-wheel drive car competition. The key point for this type of track modification is to pay attention to the speed of the vehicle not too fast and maintain stability when going downhill.

The reason may be 1: the motor shaft burned out. 2: The battery is less than 3: The conductive sheet is not installed.

When you talk about Wu Rang Equipment, you need to consider how much current is required when the motor is rotating at full speed with a load. When your battery capacity.

When the motor is not running enough, a fault similar to that you mentioned will occur. It is advisable for you to replace the battery with a larger capacity. It is best to have a lithium battery (light weight, large capacity, and long-lasting power supply).

There are also a variety of winding methods when winding the motor, the most basic is to remember to replace the original single wire on the motor with a double wire, because the thicker metal wire has a large amount of current, and the power will be more sufficient.

The principle is: the longer the wire, the greater the torsion, and the slower the speed. Conversely, the shorter the wire, the smaller the torsional force and the faster the speed.

Winding is a kind of it.

In addition to winding the wire, I also changed the magnet.

Magnetic, more powerful.
