Is the motor air water cooler related to the direction of rotation of the motor

1. The steering of the rotor of the motor is related to the current.

Changing the direction of rotation of the rotor of the motor should be divided into two cases.

1) For AC motors.

For capacitive single-phase motors, to change the steering of this motor, it can be achieved by changing the position of the capacitor in series.

Three-phase AC asynchronous motor, to change the steering of this motor, as long as any two of the three-phase symmetrical power supply in the three-phase stator winding can be adjusted.

2) For DC motors.

Just swap the two power cords of the motor. If it is an independent excitation motor, adjusting the polarity of the excitation power supply can also achieve the purpose of changing the direction of the rotor.

2. Motor rotor: It is also a rotating part in the motor. The motor is composed of two parts, the rotor and the stator, which is used to realize the conversion of electrical energy and mechanical energy and mechanical energy and electrical energy. Motor rotors are divided into motor rotors and generator rotors.

3. The motor rotor is divided into two types: the inner rotor rotation mode and the outer rotor rotation mode. The internal rotor rotates in such a way that the core in the middle of the motor is a rotating body, and the output torque (referring to the motor) or the income energy (referring to the generator). The external rotor rotation mode takes the outer body of the motor as the rotating body, and different ways facilitate the application of various occasions.

Lianyungang is indeed better at producing sampling coolers, but you say that this is a leather bag company.

(1) Solar energy received by the solar panel per minute:

w= w/m2×6m2×60s=；

2) Car Gravity:

g=mg=600kg, the resistance of the car:

f=, car traction:

f=f=, the useful power of the electric motor converted into mechanical energy:

p useful = fv =

Total power of the motor:

A: (1) The solar energy received by the solar panel per minute is;

2) The average resistance experienced by the car is; The efficiency with which an electric motor converts electrical energy into mechanical energy is.

Electrical engineering mainly talks about the principles and applications of generators and motors. I haven't learned the basics of motors and drag, I have learned electric drag technology, mainly talking about the application of drag systems in power electronics.

Dude, it's better to take a look at it yourself if you have this effort, this experiment is not difficult, and the answers to the later thinking questions can even be found in the electrician book and the electrician tutorial book. If it's not good, let's look for the classmates you did, because the experimental reports we did this experiment were all taken back by the school.
