The BYD Atto 3, also marketed as BYD Yuan Plus (Chinese: 比亚迪元PLUS) in China and several Latin American countries, is a battery electric compact crossover SUV manufactured by BYD Auto. Part of the BYD Yuan series that is named after the Yuan dynasty , [ 8 ] the Yuan Plus was released in mainland China in February 2022.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
is the motor velocity, or motor speed, [2] constant (not to be confused with kV, the symbol for kilovolt), measured in revolutions per minute (RPM) per volt or radians per volt second, rad/V·s: [3]
Powered by a bank of storage batteries, the motor was placed in front of the rear wheel. Speed control was by a resistance placed across the handlebars. This electric bicycle was mainly intended for racetrack use. [3] The October 1911 issue of Popular Mechanics mentioned the introduction of an electric motorcycle. It claimed to have a range of ...
A piezoelectric motor or piezo motor is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied. Piezoelectric motors make use of the converse piezoelectric effect whereby the material produces acoustic or ultrasonic vibrations to produce linear or rotary motion. [ 85 ]
The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...
The coils may span several slots in the stator core, making it tedious to count them. For a 3-phase motor, if you count a total of 12 coil groups, it has 4 magnetic poles. For a 12-pole 3-phase machine, there will be 36 coils. The number of magnetic poles in the rotor is equal to the number of magnetic poles in the stator.
The Honda PC50 is a moped produced by the Honda Motor Company in Japan from May 1969 until at least 1983. The PC50, though much smaller and lighter, had some similar features to Honda's popular C50 /70 /90 Super Cub line, with a step-through pressed-steel frame, a fuel tank under the saddle, a chain cover, and optionally equipped with leg shields,
