A commercial washing machine is intended for more intensive use than a consumer washing machine. [146] Durability and functionality is more important than style; most commercial washers are bulky and heavy, often with more expensive stainless steel construction to minimize corrosion in a constantly-moist environment.
A vertical-axis washing machine has two mechanisms: a central agitator for washing and a drum for spinning, both driven by the same motor and controlled independently by clutches to the belt drive. The wig-wag is mounted atop the washing machine's transmission, where it oscillates back and forth like a railroad signaling wigwag (hence the name ...
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...
Direct-drive mechanisms are used in applications ranging from low speed operation (such as phonographs, telescope mounts, video game racing wheels and gearless wind turbines) [14] [15] [16] to high speeds (such as fans, computer hard drives, VCR heads, sewing machines, CNC machines and washing machines.)
