An improved housing structure for an outer motor housing shell having slots for ventilating purposes, including a protective cover detachably fastenable to the outer face of the housing shell, the cover having a depending skirt sized and contoured to extend spacedly opposite the slots to protect the motor from falling rain, and yet permit proper ventilation.

Protective cover for slotted motor housing shell structure

A motor starting switch mountable on an electric motor and actuatable by a centrifugal actuator for energizing the starting winding of the motor during start up of the motor and for deenergizing the starting winding or other circuits upon the motor attaining a desired operating speed. A toggle linkage for operatively connecting the motor starting switch to the centrifugal actuator is included as a part of this motor starting switch, and it includes a slider for opening and closing one or more sets of contacts within the starting switch housing movable in the same direction as the actuator member of the centrifugal actuator, and a lever pivoted to the switch housing and engageable by the centrifugal actuator. The slider is privotally connected to the lever so that upon the centrifugal actuator pivoting the lever, the slider is moved to open or close the contacts.

A terminal connection board finding application with dynamoelectric machines is provided with an integrally formed insulated pocket. In dual voltage motors, final connection of the motor in a particular application is not always determined until the motor is inserted in that application. When motors rated at 115/230 volts are employed in 230 volt source applications, for example, one motor lead is disconnected at the terminal board. The insulated pocket of this invention provides a safe receptacle for that motor lead. Preferably, the pocket includes a locking device for holding the motor lead within the pocket after its insertion.
