Abstract
A pellet dispenser unit in which a container of pellets can be attached to a motor and rotor assembly while the container is in an upright position. After attachment with the container, the container is inverted and the motor and rotor with the container are placed in a housing member from which the pellets are dispensed. The motor is electrically connected automatically when the motor and rotor assembly is placed in the housing member. In a preferred manner, plastic foam is placed in a housing for the motor and rotor to protect the motor as well as a circuit board from any corrosive fumes. The motor and rotor assembly are placed in a housing which is constructed so as to be easily handled by one hand for ease of attachment to the container when the container is in an upright position and the motor and rotor assembly inverted.
