www.imca.commotor[′mōd·ər] (electricity) A machine that converts electric energy into mechanical energy by utilizing forces produced by magnetic fields on current-carrying conductors. Also known as electric motor. (neuroscience) Pertaining to efferent nerves which innervate muscles and glands. (physiology) That which causes action or movement. Motor A machine that converts electrical into mechanical energy. Motors that develop rotational mechanical motion are most common, but linear motors are also used. A rotary motor delivers mechanical power by means of a rotating shaft extending from one or both ends of its enclosure (see illustration). The shaft is attached internally to the rotor. Shaft bearings permit the rotor to turn freely. The rotor is mounted coaxially with the stationary part, or stator, of the motor. The small space between the rotor and stator is called the air gap, even though fluids other than air may fill this gap in certain applications. In a motor, practically all of the electromechanical energy conversion takes place in the air gap. Commercial motors employ magnetic fields as the energy link between the electrical input and the mechanical output. The air-gap magnetic field is set up by current-carrying windings located in the rotor or the stator, or by a combination of windings and permanent magnets. The magnetic field exerts forces between the rotor and stator to produce the mechanical shaft torque; at the same time, in accord with Faraday's law, the magnetic field induces voltages in the windings. The voltage induced in the winding connected to the electrical energy source is often called a countervoltage because it is in opposition to the source voltage. By its magnitude and, in the case of alternating-current (ac) motors, its phase angle, the countervoltage controls the flow of current into the motor's electrical terminals and hence the electrical power input. The physical phenomena underlying motor operation are such that the power input is adjusted automatically to meet the requirements of the mechanical load on the shaft. See Electromagnetic induction, Magnet, Windings in electric machinery Both the rotor and stator have a cylindrical core of ferromagnetic material, usually steel. The parts of the core that are subjected to alternating magnetic flux are built up of thin steel laminations that are electrically insulated from each other to impede the flow of eddy currents, which would otherwise greatly reduce motor efficiency. The windings consist of coils of insulated copper or aluminum wire or, in some cases, heavy, rigid insulated conductors. The coils may be placed around pole pieces, called salient poles, projecting into the air gap from one of the cores, or they may be embedded in radial slots cut into the core surface facing the air gap. In a slotted core, the core material remaining between the slots is in the form of teeth, which should not be confused with magnetic poles. See Eddy current Direct-current (dc) motors usually have salient poles on the stator and slotted rotors. Polyphase ac synchronous motors usually have salient poles on the rotor and slotted stators. Rotors and stators are both slotted in induction motors. Permanent magnets may be inserted into salient pole pieces, or they may be cemented to the core surface to form the salient poles. The windings and permanent magnets produce magnetic poles on the rotor and stator surfaces facing each other across the air gap. If a motor is to develop torque, the number of rotor poles must equal the number of stator poles, and this number must be even because the poles on either member must alternate in polarity (north, south, north, south) circularly around the air gap. motorA machine which converts electric power into mechanical power by means of a rotating shaft.motor

See Broca's/Motor aphasia, Sensory/Wernicke's aphasia, Tactile aphasia. Aphasia - Motor
- Broca's aphasiaA primary deficit in language output or speech production, which ranges in severity from the mildest, cortical dysarthria, characterized by intact comprehension and ability to write, to a complete inability to communicate by lingual, phonetic, or manual activity
- Sensory
- Wernicke's aphasiaPts with sensory aphasia are voluble, gesticulate, and totally unaware of the total incoherency of their speech patterns; the words are nonsubstantive, malformed, inappropriate–paraphasia Sensory aphasia is characterized by 2 elements: Impaired speech comprehension–due largely to an inability to differentiate spoken and written phonemes–word elements-due to either involvement of the auditory association areas or separation from the 1º auditory complex Fluently articulated but paraphasic speech, which confirms the major role played by the auditory region in regulating language
- Total
- Global aphasia, complete aphasiaA form of aphasia caused by lesions that destroy significant amounts of brain tissue, eg occlusion of the middle cerebral or left internal carotid arteries, or tumors, hemorrhage, or other lesions; total aphasia is characterized by virtually complete impairment of speech and recognition thereof; afflicted Pts cannot read, write, or repeat what is said to them; although they may understand simple words or phrases, rapid fatigue and verbal and motor perseverence, they fail to carry out simple commands; total aphasia of vascular origin is almost invariably accompanied by right hemiplegia, hemianesthesia, hemianopia of varying intensity
