Abstract

A dynamoelectric machine is provided with improved connection structure which does not require external leads and which provides an integral ground connection for the dynamoelectric machine. The dynamoelectric machine is a motor, which includes a stator assembly, having a motor winding which is terminated at the winding ends with quick connected terminals. The motor includes at least one end shield. A terminal receptacle is designed to mount internally of the motor endshield. The terminal receptacle includes provisions for holding the ground terminal positionally, and is provided with a spring loading mechanism for loading the receptacle against the endshield. The terminal receptacle has an external latch which receives an associated terminal block in locking arrangement, normally being accompanied with an audible signal. The receptacle preferably is color coded to give a visual indication as to motor rating or identifying different motor types, for example.
