Abstract
Abstract A mounting bracket assembly is provided for mounting peripheral equipment to an electric motor. The bracket is suited particularly for use with various motor types where a stator assembly and rotating member are supported by bearings fitted along end shield structures. More specifically, the bracket is advantageous where an electrical switch and motor protector are preassembled to it. The bracket thereafter is attached to the electric motor, and may be removed easily if the motor fails for any reason.
