What level of performance can a racing car achieve if it were to switch to an electric motor?

The performance will be very open, and the instantaneous explosive power will be gone.

The 24 Hours of Le Mans had to be renamed the 96 Hours of Le Mans (120 hours is not impossible.)

Switching to electric motors in racing cars will reduce performance a lot.

The estimated performance of changing to electric will be poor.

I think the biggest speed limit is friction.

I haven't changed it, and I'm not sure what level I can reach.

The electric motor certainly won't be able to play at the modified engine speed.

I don't think the motor will be as good as before.

I don't think the speed of the motor will reach very high.

I think the performance may not be as good as it used to be.

（1）∵i=u

r When the motor is not rotating, the resistance of the motor coil: r=u

i=6v2a=3ω；

2) The heat generated by the rotation of the motor can be obtained from Joule's law: q=i2rt=(;

3) The electrical energy consumed in the same time is: w=pt=uit=6v, then the mechanical efficiency is: =w?q

w×100%=216j?216j

Answer: (1) then the resistance of the motor coil is 3;

2) The heat generated by the toy motor for 1min when the motor rotates normally is;

3) The efficiency of this motor to convert electrical energy into mechanical energy is 70%.

The specific data is all above.

The chassis body of the F2007 is significantly different from last year's model 248 F1, the newly designed suspension system introduces an innovative concept, most of the changes are in the aerodynamic package, the side panels and the front are also corrected, this is to match the cooling system, so the radiator outlet and the air intake of the engine will change with the change, the wheelbase of the car is longer than the previous one, the rear is narrower, which is conducive to the placement of the gearbox, the gearbox still has the same seven gears, and the rear suspension system is very similar to the 248 F1, However, there has been an evolution of R&D to match the 2007 Bridgestone tires.

As for the front and rear aerodynamic packages, it is expected that there will be changes before the start of the season, but last year the special position of the rear mirrors will be maintained, and the exhaust system will remain the same, and generally speaking, although the design and development of the car is completed, the most important key is the seamless technical cooperation, Ferrari still uses Shell's fuel and lubricants, and the simulation tests are carried out at the Fiat research center, while Brembo is responsible for the development of the braking system. The new car will make its debut tomorrow at the Fiorano circuit by Massa.

Atomic fission doesn't seem to be very good, I heard my brother say it once, and he thinks it's not good.

The good ones are still the speed of light, the speed of sound, the whirlwind, and the violence, which can be said to be recognized.

The principle of a DC motor is that an energized conductor is subjected to a force in a magnetic field. It can be divided into permanent magnet type or DC electromagnetic type.

The working principle of a three-phase asynchronous motor: three-phase alternating current generates a rotating magnetic field. Three-phase AC motors are divided into stator windings and rotors.

When a symmetrical three alternating currents are introduced into the three-phase stator winding, a rotating magnetic field is generated that rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed n1. Since the rotating magnetic field rotates at n1 rotational speed, the rotor conductor is stationary at the beginning, so the rotor conductor will cut the stator rotating magnetic field and generate an induced electromotive force (the direction of the induced electromotive force is determined by the right-hand rule). Since the two ends of the rotor conductor are shorted by short-circuit rings, under the action of induced electromotive force, the induced current in the rotor conductor will be basically consistent with the direction of the induced electromotive force.

The current-carrying conductor of the rotor is subjected to an electromagnetic force in the stator magnetic field (the direction of the force is determined by the left-hand rule). The electromagnetic force generates electromagnetic torque on the rotor shaft and drives the rotor to rotate in the direction of the rotating magnetic field.

1) Because the process of racing car from B to C is a flat throwing motion, there is according to the law of flat throwing motion. vy2gh3m/svc

2) In the process of moving from point C to the highest point D, the mechanical energy is conserved.

The motor that goes around by itself.

I make it for one's own car fit.

Tamiya model motor or homemade.

The effect of the magnetic old trembling dust field on the current by force. The current goes north, the magnetic field goes underground, and the force goes west. The electric motor force has a rectangular electric coil, and the two attendants are flanked by two magnets.

When there is current, the coil rotates due to the magnetic force between the magnet and the coil; When there is no current, the coil will continue to rotate due to inertia until there is an electric current, and then the force will occur, so that it will rotate continuously. This can only be explained clearly if there is a picture, and it will be taught in high school.

The problem is less conditional, and the value of the power supply voltage is missing.

First question: p1 u

Second question: p2 i 2r, r u 2, i

Question 3: P loses p1 p2
