A motor including a plurality of temperature monitoring sensors is described. The temperature monitoring sensors are attached to stator coils and stator winding phases of the motor. The temperature monitoring sensors include a face side and a lead side which are positioned along the stator winding phases to properly monitor the motor temperature prior to insertion of the winding phases into a stator iron.

Electric motors and methods for assembling temperature sensors therein

An electric motor assembly capable of withstanding heavy side loading includes a motor housing having a shell with first and second end shields including bearing supports having bearings therein. The first end shield further includes a flange for connecting a compressor to the motor. A rotor is rotatably mounted in the housing and supported by the bearings. A stiffening collar, positioned between a rotor core and the first end shield, surrounds a portion of a rotor shaft and provides support for the shaft against deflection due to heavy side loading. A centrifugal mechanism and a spacer are positioned on the rotor assembly outboard of the motor housing. The motor assembly also includes a cover attached to the second end shield. The cover holds a start capacitor, a run capacitor and a centrifugal switch and further includes snaps for mounting the centrifugal switch to the cover. An overload and an overload bracket extend, at least partially, through an opening in the second end shield. The overload bracket includes snaps that engage the second end shield and maintain the bracket and overload in position. A load washer having a plurality of snaps engages the second end shield and maintains the load washer in position on the second end shield.

Shaft support assembly for direct drive motor

The application discloses new modes of changing the length of pinch roller fed wedge material that involves transmitting motive power from a power shaft to a driven pinch roller through a power train that includes at least one pivoting lever, the effective length of which is quickly changed by moving a pivot shaft which supports such lever. Power is supplied through a first link from a main drive shaft to a pivoting slider, and then to a rocker arm or a lever which rocks about a pre-selected pivot point. Power is transmitted from such lever to a rack or other driving mechanism which then supplies motive power to a pinch wheel assembly. The pivot for the previously mentioned rocker arm is adjustable, and thereby the relative effective lengths of the rocker arm on either side of the pivot may be selectively varied in order to change the extent of rotary movement of the driven pinch roller even though the first drive link continues to travel along a fixed path.

Apparatus for controlling the length of wedges

Monitor position of winding flyer in relation to a machine frame, substantially continuously generate signals indicative of flyer position, and control relative jump of coil forms and flyer in response to signals. Jump is initiated during predetermined portion of a flyer revolution while flyer is in 'jump window' relative to turn receiver. Energy stored in lost motion mechanism contributes to acceleration of jump mechanism; and same mechanism absorbs and stores energy as moving structure stops. Parts of coil forms are adjusted substantially equal distances relative to a geometric center and turn receiver and winding head undergo relative movement to maintain mutually aligned relationships. Fast and consistently responsive latch mechanisms insure jump during fraction of flyer revolution in different machine cycles. Jump mechanism urged against latches by pre-loaded spring mechanism for increased acceleration and to absorb prime mover force at end of jump stroke. Fast response diaphragm piston operated latch mechanisms perit initiation of jump stroke. Means adjust coil form parts in opposite directions while form parts remain centered relative to flyer axis. Device maintains desired alignment of at least one coil form part and winding turn receiver. Screw with spaced apart right-hand and left-hand threads move coil form parts relative to one another.
