   Motor Type       
   Your choices are...         
   DC Motor       Class of motors that use direct current (DC). DC motors are most commonly used in variable speed and torque applications. 
   AC Motor       Class of motors that use alternating current (AC). AC motors include a variety of types including synchronous, induction, AC servomotors, and single and multiphase motors. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   DC Servomotor       DC servomotors have an output shaft that can be positioned by sending a coded signal to the motor.  As the input to the motor changes, the angular position of the output shaft changes as well. Servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gearmotor types. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Stepper Motor       Stepper motors provide incremental motion, or steps, in response to pulses of current that alternately change the polarity of the stator poles. Step motors do not require feedback and are sometimes used in "Open Loop," or no-feedback applications. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

   Special / Extreme Environments       
   Your choices are...         
   Clean Room Use       Clean rooms are classified by particulate size and density in the ambient air. One such rating method classifies rooms according to number of particles larger than 0.5 micron in one cubic foot of air. There are various governmental, metric, and international standards. Motors rated for suitability in a clean room will identify the particular standard for which they are rated. 
   Cryogenic Use       Motors with a cryogenic rating are constructed for extremely low ambient temperatures such as 20 K and below. 
   Explosion-proof       Explosion-proof motors have totally enclosed housings that are constructed to withstand internal explosion of a specified gas, vapor, or dust. Should such an explosion occur, the enclosure would prevent the ignition or explosion of the gas or vapor surrounding the motor enclosure. Several explosion-proof ratings are governed by Underwriter's Laboratories (UL). 
   Radiation-hardened       Radiation-hardened motors are constructed of materials designed to withstand high-energy gamma radiation. Ratings are expressed in units such as permissible RADs in total accumulated dose (TAD). 
   Vacuum Use       Vacuum-rated motors incorporate features such as lubricant vapor pressure below rated ambient vacuum and construction techniques.

AC Motor Specifications
   Voltage & Frequency:       
   Your choices are...         
   115 / 120V 60 Hz       115 / 120V is standard residential or commercial voltage for 60Hz power (North America). 
   208-230 / 240V 60 Hz       These are for 60Hz power (North America).

   Phase       
   Your choices are...         
   Single-phase       Standard commercial and residential power is single-phase, meaning one sinusoidal or other alternating voltage pattern. 
   Three-phase       Three-phase power contains three simultaneous sinusoidal or other alternating voltage patterns, typically 120° out of phase with each other. Higher power efficiency and smoothness of operation is possible with three-phase operation. Three-phase power is most typically used for industrial or high power motors. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   AC Motor Construction:       
   Your choices are...         
   Induction       Induction motors derive their name from the fact that current is induced into the rotor windings without any physical connection with the stator windings (which are directly connected to an AC power supply). Induction motors are adaptable to many different environments and capable of providing considerable power as well as variable speed control. Typically there is "slip," or loss of exact speed tracking with induction motors. 
   Synchronous       Synchronous motors operate at constant speed up to full load. The rotor speed is equal to the speed of the rotating magnetic field of the stator; there is no slip. Reluctance and permanent magnet are the two major types of synchronous motors. A synchronous motor is often used where the exact speed of a motor must be maintained. 
   AC Servomotor       AC servomotors are typically permanent magnet, synchronous motors that can often have low torque-to-inertia ratios for high acceleration ratings. 
   Universal       Universal motors can operate at approximately the same speed and output on either DC or single-phase AC power. Universal motors are also known as an AC/DC motors. 
   Other       Unlisted or specialized AC motor construction. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

DC Motor Specifications
   DC Terminal Voltage:       Design DC motor voltage. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   DC Motor Construction       
   Your choices are...         
   Permanent Magnet       Permanent magnets (PM) are embedded into the rotor assembly. The rotor aligns itself with the rotating magnetic field of the stator windings. PM motors exhibit constant speed with varying load (zero slip) and provide relatively high torque, good efficiency, and lower current draw than comparable synchronous motors. 
   Shunt Wound       Shunt wound motors exhibit minimum speed variation through a load range and can be configured for constant horsepower over an adjustable speed range. Frequent applications include machine tools, fans, and blowers. 
   Series Wound       Series wound motors exhibit high starting torques for permanently attached loads. These motors are frequently used in heavy industrial applications. 
   Compound Wound       Compound wound motors are designed with both a series and shunt field winding. They are often used where the primary load requirement is heavy starting torque, and adjustable speed is not required. They can exhibit speed variation from no-load to full-load. Applications include elevators, hoists, and industrial shop equipment. 
   Disc Armature       Disc armatures are flat, pancake-shaped rotors that are driven by an axially, rather than radially, aligned magnetic field. The thin construction of these armatures can result in low inertia with resulting high acceleration. 
   Coreless / Slotless       Coreless and slotless motors incorporate cylindrical winding that is physically outside of a set of permanent magnets. Because the winding is laminated and excludes an iron cage, these designs have much lower inertia. They boast high acceleration, high efficiency, excellent speed control, and little to no vibration. They are commonly used as servomotors for process control applications. 
   Other       Unlisted motor construction. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Commutation       
   Your choices are...         
   Brush       Brush motors have the armature windings on the rotor. The magnetic fields are commutated via direct contact of brushes with the rotor commutator. 
   Brushless       Brushless motors have their armature windings on the stator and the field on the rotor. They rely on internal noncontact sensing devices to activate external commutating electronics. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Gearmotor / Gearhead Options
   Gearing Arrangement:       
   Your choices are...         
   Spur       Spur gear heads include one or more sets of pinion-gear sets, in which one pinion drives one gear. These sets can be stacked or cascaded to achieve higher reduction ratios. 
   Planetary       Planetary gear heads involve several gears per stage rather than one pinion-gear set. A "sun gear" drives multiple planet or satellite gears, which then mesh on the inside of an internal or annular gear to provide relatively high torque and power transmission ratings. 
   Harmonic       Harmonic drives are extremely precise speed reduction systems, which transmit power via a rotating elliptical element that engages a flexible cup that then engages an internal gear, typically fixed. This power transmission delivers precise angular position in very high input-to-output ratio (50:1 & up) applications. 
   Worm       Worm gearing uses right-angled drives in which a worm drives a wheel coupled to the output shaft or shafts. This arrangement is used for high reduction and compact right-angle power transmission. 
   Bevel       Bevel gear sets have intersecting axes that are commonly, but not always, perpendicular. They mate via teeth on angled edges. 
   Other       Unlisted or specialized gearing arrangement. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Gearbox Ratio:       Gearbox ratio is the ratio of input speed to output speed. A ratio greater than one indicates speed reduction, while a ratio less than one indicates speed increase. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Gearbox Efficiency:       Efficiency is the percentage of power or torque that is transferred through a gearbox. Losses occur due to factors such as friction and slippage inside the gearbox. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
