Does simplicity translate to more or less grunt?Ĭombustion engines need to be “revved-up” to reach peak power and torque. Their simplicity also means that almost no energy is lost in friction between moving parts, making them far more efficient than internal combustion engines. Given the minimal moving parts, electric motors are also highly reliable and require little to no maintenance. On the other hand, the electric motor reacts instantly as soon as the accelerator is pushed.
#ELECTRICT MOTOR DRAG RACING GENERATOR#
The added benefit of this design is that it can operate in reverse, acting as a generator to charge the batteries while slowing down the vehicle (this is called regenerative braking). The rotor is turned by a surrounding magnetic field, which is generated using electricity.

So how are electric motors different? Electric motors are actually pretty simple, consisting of a central rotor, typically connected to a single gear. Why battery-powered vehicles stack up better than hydrogen This is why combustion engine cars are very energy inefficient. The gearbox attempts to keep the engine running close to this peak efficiency across a wide range of speeds.Īll of this complexity leads to a significant amount of energy being lost, mostly through friction (heat).

The engine must be “revved-up” to a high number of revolutions in order to reach peak efficiency. This is a rather simplified overview, but there are literally hundreds of moving parts in a combustion engine.
#ELECTRICT MOTOR DRAG RACING MOD#
Technically a Pro Mod dragster must meet the following. Credit REA A pro mod dragster is a car, specially built for drag racing, that sometimes resembles an existing model but actually all forms are possible. The decoupling must be clearly identifiable and visible. These pistons drive a crankshaft, which is then connected to a gearbox, and eventually the wheels. Engine must have the ability to quickly disconnect motor current. In an internal combustion engine, as the name suggests, small amounts of fuel are mixed with air, and are exploded to drive a series of pistons. Internal combustion engines and electric motors are very different.
