The latest Facebook Marketplace scam to watch out for: a scheme that sold rented cars for cash on the online secondhand shopping platform.
The windings (coils of wire) on the armature are connected to the commutator segments. Commutators are used in direct current (DC) machines: dynamos (DC generators) and many DC motors as well as universal motors. In a motor the commutator applies electric current to the windings.
In many car washes, the mitter curtains are operated in place of top brushes (in some countries, the opposite happens). Some car washes carry both mitter curtains and top brushes, [7] [8] while others carry multiple mitters. [9] The curtains are often preceded by rinse arches and followed with a foam applicator and car wash brushes. [10]
A telephone magneto is a hand-cranked electrical generator that uses permanent magnets to produce alternating current from a rotating armature. In early telegraphy , magnetos were used to power instruments, while in telephony they were used to generate electrical current to drive electromechanical ringers in telephone sets and activate signals ...
A compensation winding in a DC shunt motor is a winding in the field pole face plate that carries armature current to reduce stator field distortion.Its purpose is to reduce brush arcing and erosion in DC motors that are operated with weak fields, variable heavy loads or reversing operation such as steel-mill motors.
A VHS tape rewinder is an electronic device used to rewind VHS tapes. Rewinding is necessary because VHS tapes are irreversible [clarification needed]: they contain only one audio/video-track intended for playback in one direction.
