Motor thumb|282x282px|The exposed mechanism of the motor and rubber pulley is shown. Vibraphones usually have an electric motor and pulley assembly mounted on one side or the other to drive the disks in the resonators. Often, especially within classical music, the vibraphone is played with the motor off. Certain models for outdoor use as part of a front ensemble have the motor removed entirely. In those cases having the motor off is the norm and is not used unless specifically called for.
