The electric motor is used for propulsive power as often as possible in this situation.

An old man was effortlessly cycling past me, laughing and pointing to the electric motor attached to his bike.
The 1.4-liter gasoline engine under the hood functions as a generator, creating juice for the electric motor.
His discoveries laid the foundations for the electric motor and the electrical generator, and thus for electrification in general.
The electric motor dishes out gobs of linear, head-snapping torque, quickly propelling you past the speed limit -- you've been warned.

The system delivers about 165 watts of power per hour to an added battery, which helps powers the electric motor, Johanson said.
That hybrid car that you smugly drive contains about 100 pounds of the stuff, largely in the electrical cables and the electric motor.
Once out in traffic, I appreciated how the electric motor assistance gave me the necessary speed to keep up with the red double-decker buses.
The electric motor produces 107 horsepower and 201 foot-pounds of torque--more than enough oomph to merge safely and smoothly onto Detroit's notoriously high-speed freeways.
An electric boost function helps in instances where maximum acceleration is desired, when the electric motor works in tandem with the combustion engine during acceleration.

In electric cars and hybrids like the Prius, the electric motor that drives the wheels is likewise made to run backwards as an alternator during braking.
The hybrid recaptures energy through a process known as regenerative braking -- where the energy normally lost through braking or coasting goes to power the electric motor.
For an example, in a hybrid car, a radiator works to cool the combustion engine while a second radiator cools the power electronic system that runs the electric motor.

By applying the brakes or reducing speed by letting off the accelerator, the electric motor acts as an electric generator, converting energy that would otherwise be wasted into battery energy.

In this case, however, the front electric motor-which is now supplied with energy by the TDI engine-operates exclusively as a generator and a power source for the electric motor at the rear.

Severinsky's bright idea was to run the electric motor on a high voltage--say, 40 times the 14 volts that is standard for the electrical system in a gasoline car with a 12-volt battery.
If something gets in the way of the door--a person's foot or a roof panel that's hanging down--the electric motor that closes the train door has to work harder and produces more current.
Mash the pedal in Auto EV mode and, after the electric motor pulls you off the line, there's a brief delay before the gasoline engine comes to life and the CVT raises the RPMs to maximize efficiency.

Putting more than half a million road miles on development versions of the Spark EV enabled engineers to make the performance of the electric motor the best it could be by using a bar wound copper stator and unique rotor configuration.

In addition to the petrol engine and electric motor, the LF-CC hybrid drive system further comprises a generator, a high-performance battery, a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements, and a compact power control unit to govern the high speed interaction of the system components.

Nikola Tesla's invention of the electric induction motor in 1883 only strengthened AC's industrial dominance, since the motors could run only on AC.

Because peak power arrives at different rpm for the gas engine and the electric traction motor, peak system horsepower nets out to be an even 200 hp at 5, 600 rpm, which is the rated redline.

It also, though, has an electric motor that provides additional power to the rear wheels (through the same gearbox) and a second electric motor connected directly to the front axle.
ECONOMIST: Fast cars will go even faster with electric power
On the other side the electrons return via the second electrode, having passed through the coils of an electric motor that drives the wheels of the car.
In E-mode, only the 114-hp rear electric motor propels the vehicle and the TDI engine is shut off and decoupled from the drivetrain.

In the latter scenarios, the regenerative drive generates electric power as the motor rotates backwards.
FORBES: Gravity May Soon Qualify As Renewable-Energy Resource in New York
The SUV features a front-mounted diesel engine paired with an electric motor in a traditional hybrid configuration, plus a second, more powerful electric motor in the rear to drive those wheels in the back.
The electric drive produces 95 hp, more than double the power of the previous model's electric motor (47 hp).
