Website. gem.polaris.com. Global Electric Motorcars (GEM) is an American manufacturer specializing in neighborhood electric vehicles (NEVs) since 1998 and low-speed vehicles (LSVs) since 2001. By October 2015 [1] the company had sold over 50,000 GEM battery-electric vehicles worldwide. Originally owned by Chrysler, GEM was acquired by Polaris ...
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to ...
Aptera Solar EV. The Aptera [b] is a two-seat, three-wheeled solar electric vehicle under development by the crowd-funded American car manufacturer Aptera Motors. The stated design goal of the car is to be the most energy efficient mass produced vehicle ever. The design has an aerodynamic shape and uses lightweight carbon fiber and fiberglass ...
An electric car or electric vehicle (EV) is a passenger automobile that is propelled by an electric traction motor, using only energy stored in on-board batteries.Compared to conventional internal combustion engine (ICE) vehicles, electric cars are quieter, more responsive, have superior energy conversion efficiency and no exhaust emissions and lower overall vehicle emissions (however the ...
Crude electric carriages were first invented in the late 1820s and 1830s. Practical, commercially available electric vehicles appeared during the 1890s. An electric vehicle held the vehicular land speed record until around 1900. In the early 20th century, the high cost, low top speed, and short-range of battery electric vehicles, compared to ...
A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect. An electrical circuit makes acoustic or ultrasonic vibrations in the piezoelectric material, most often lead zirconate titanate and ...
A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance . Reluctance motor subtypes include synchronous, variable, switched and variable stepping. Reluctance motors can deliver high power density at ...
A “life and death race” has begun to unfold in the world’s largest market for electric vehicles. Many players won’t reach the finish line. A brutal elimination round is reshaping the world ...
