Direct-drive systems are characterized by smooth torque transmission, and nearly-zero backlash. [9] [10] [11] The main [citation needed] benefits of a direct-drive system are increased efficiency (due to reduced power losses from the drivetrain components) and being a simpler design with fewer moving parts.
The SmartDrive also included a direct drive brushless DC electric motor, which simplified the bowl and agitator drive by eliminating the gearbox system. In 2000, the British inventor James Dyson launched the CR01 ContraRotator , a type of washing machine with two cylinders rotating in opposite directions.

In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables for turntablism, since they have a slower start-up time and torque, and are prone to wear-and-tear and breakage, [5] as the belt would break from backspinning or scratching.

The first phone of any kind with a large capacitive touchscreen was the LG Prada, announced by LG in December 2006. [37] This was a fashionable feature phone created in collaboration with Italian luxury designer Prada with a 3" 240 x 400 pixel screen, a 2-Megapixel digital camera with 144p video recording ability, an LED flash , and a miniature ...
Acorn's own expansion strategy was led by the Plus 1 which offered a combination of ports and cartridge connectors, [137] followed by the Plus 3 disc drive unit, but by early 1986 the more general range of expansions had broadened to include floppy drive and RS423 interfaces, Teletext adapters, and other fundamental enhancements to the base ...
Most 2010s and 2020s-era personal computers require users only to plug in the power supply, monitor, and other cables. A typical desktop computer consists of a computer case (or tower), a metal chassis that holds the power supply, motherboard, a storage device such as a hard disk drive or solid-state drive, and often an optical disc drive. Most ...
