In the transference of power, some washing machines were chain driven, some belt driven and others used shafts and gears. To overcome the initial resistance in starting a washing machine, a fractional horsepower motor which would not burn out or overheat during the start-up period was used.

To prevent electric shocks, the stator and rotor of the machine were enclosed in a housing equipped with a fan to prevent overheating.
