A washing machine having a variable speed motor. The washing machine has a basket for holding articles to be washed and has a first axis of rotation. A basket drive shaft connected to the basket drives the basket. An agitator disposed in the basket along the first axis of rotation agitates the article in the basket. An agitator drive shaft connected to the agitator drives the agitator. A variable speed motor, having a second axis of rotation which is not coincident with the first axis of rotation, drives the basket drive shaft and the agitator drive shaft. A coupler couples motion of the variable speed motor to the agitator drive shaft and basket drive shaft.
