Abstract
A mounting clip for securing a motor protector to the stator of an electric motor is described. In one embodiment, the mounting clip includes a protector holding region formed by a base portion, a back portion, arm portions, and a retaining member. The protector is positioned within the protector holding region. The base of the mounting clip seats upon the uppermost, or outermost, lamination of the lamination stack forming the motor stator and includes one or more fingers sized for insertion between adjacent stator winding gaps. The mounting clip is maintained in position by the friction fit between the clip fingers, the stator windings and insulation.
Claims19
A mounting clip for securing a motor protector to a stator of an electric motor, the stator forming a rotor bore and having a plurality of stator teeth extending radially inward towards the bore, adjacent stator teeth defining slot, at least one stator winding being inserted within selected slots and forming winding gaps at an outer surface of the stator teeth, said mounting clip comprising:
- a base having a front portion and a rear portion, said front portion comprising at least one finger segment configured for being positioned in a selected winding gap over one of said stator teeth;
- and
- a back portion extending from said rear portion of said base, a protector holding region formed by said base and said back portion.
A dynamoelectric machine comprising a stator which forms a rotor bore and has a plurality of stator teeth extending radially inward towards said rotor bore, adjacent stator teeth defining slots, at least one winding being inserted within selected slots and forming winding gaps at an outer surface of said stator teeth, a motor protector, a mounting clip for securing said motor protector to said stator, said mounting clip including at least one finger segment extending into one of said winding gaps over one of said stator teeth.
A method of securing a motor protector and a mounting clip to a stator of an electric motor, the stator forming a rotor bore and having a plurality of stator teeth extending radially inward towards the rotor bore adjacent stator teeth defining slots, at least one stator winding being inserted within selected slots and forming winding gaps at an outer surface of the stator teeth, the mounting clip comprising a protector holding region and at least one finger segment, said method comprising the steps of:
- coupling the motor protector in series circuit with the stator winding;
- placing the motor protector in the holding region of the mounting clip;
- and
- securing the mounting clip to the stator by inserting the finger segment of the mounting clip into a winding gap over one of said stator teeth wherein at least a portion of the motor protector is in thermal communication with at least a portion of the stator winding.
