An electric machine includes a motor having a motor chassis having a first and second end, a stator assembly, and a rotor assembly. The electric machine includes a motor control assembly having a circuit board. The motor control assembly is attached to the stator assembly of the motor. A first end shield is attached to the first end of the motor chassis. The first end shield includes a first opening that is configured to enable a cooling air stream to pass therethrough to cool the motor and the motor control assembly.

Methods and apparatus for mounting a motor controller on a stator assembly

In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a shaft comprising an outer diameter, a first hub coupled about the shaft outer diameter, and a first plurality of pole pieces positioned radially about the hub. The rotor further includes a plurality of permanent magnets positioned radially about the hub. The plurality of pole pieces and the plurality of permanent magnets define a rotor outer diameter, and the rotor outer diameter is magnetically isolated from shaft.

Radially embedded permanent magnet rotor and methods thereof

A method for fabricating a motor is described that includes attaching a circuit board of a motor control assembly to a first side of a mounting adapter, and attaching a second side of the mounting adapter to a stator assembly.

An operator sequentially inserts into an automated system for making armatures for electrodynamic machines loaded magazines containing a required number of hairpin conductors for an armature to be made, an armature core comprising a plurality of substantially aligned laminations preassembled to form the core and a commutator, and removes armatures completed by assembling these components. All the insertion and removal steps are performed from an operator's position such that operation of the system embodying the present invention is easily and conveniently performed even though the components and completed armatures can be of substantial weight. The use of a hairpin magazine, including the hairpin conductors required for an armature, permits simultaneous transfer of all the hairpin conductors into upper twist tooling wherein upper ends of the hairpin conductors adjacent end turn portions of the conductors are moved apart relative to one another. The frog leg conductors thus formed are removed from the upper twist tooling and inserted into slots of an armature core which has been earlier inserted into the system. The frog leg conductors are fully pressed through the armature core into lower twist tooling which then is operated to move the ends of the conductors extending beyond the armature core away from one another and into alignment with other conductors for insertion into a commutator for the armature, which commutator was earlier placed into the system. The commutator is properly positioned beneath the armature core which is then pressed onto the commutator. The completed armature is moved to the operator's position where the operator removes the completed armature and replaces it with a commutator for the next armature. The operator continues to insert components of armatures into the system and removes completed armatures made up by assembling the components so inserted.

Apparatus for making armatures for electrodynamic machines

A probe for measuring the oxygen content in a fluid, particularly a molten metal, by galvanic action. The probe assembly of the invention utilizes the thermal expansive properties of the probe components to increase the physical contact pressure between the solid electrolyte and its reference electrode so as to increase its reliability, ruggedness and lifetime.
