Editing Washing machine (section)

====Reversible motor with mode-changing transmission====
Some top-loaders, especially compact apartment-sized washers, use a hybrid mechanism. The motor reverses direction every few seconds, often with a pause between direction changes, to perform the agitation. The spin cycle is accomplished by engaging a clutch in the transmission. A separate motorized pump is generally used to drain this style of machine. These machines could easily be implemented with [[universal motor]]s or more modern DC [[brushless motors]], but older ones tend to use a capacitor-start [[induction motor]] with a pause between reversals of agitation.<ref>W10329932 L-84 Whirlpool vertical modular washer job aid</ref>
