Motor Type
   Motor Type:       
   Your choices are...         
   Permanent Magnet       The motor uses a permanent magnet on the rotor. Step angles range from 1.5 to 30 degrees. Permanent magnet motors are the most common and versatile stepper motor; this includes both unipolar (bifilar) and bipolar types. 
   Variable Reluctance       Variable reluctance motors have a free-moving rotor. No residual torque is produced due to the lack of a permanent magnet. The rotor is instead composed of a soft iron metal. The rotor is also composed of its own very prominent poles, which tend to stick out more than a rotor found on the PM version. Step angles: 7.5 to 30 degrees single power source required (like a bifilar PM motor). Variable reluctance motors are the least expensive stepper motor. 
   Hybrid       Hybrid motors consist of a heavily toothed PM rotor and toothed stators, plus prominent rotor poles like a VR rotor. These motors have very fine step angles: 0.5 to 15 degrees. Hybrid motors have high-speed capability (less chance of a stall) and higher available torque than PM or VR stepper motors. Hybrids are the most effective, but most expensive stepper motor type. 
   Other       Unlisted or specialized stepper 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.
   Step Angle:       The degrees per step of the motor. 
   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.
   Number of Leads:       Stepper motor configurations can have different numbers of leads depending on the specific winding wiring. For example, bipolar PM motors can have 4, 5, or 6 leads. Unipolar PM motors can commonly have 5 or 6 leads (two windings with two ends plus center taps, which may or may not be tied together). Hybrid motors frequently contain 8 leads, and multiphase motors can have different lead configurations (for example, a motor wired for 5-phase power could have 5 or 10 leads). Consult with the manufacturer for specific winding, wiring, and lead information.

Gearmotor / Gearhead Options
   Motor Configuration:       
   Your choices are...

   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.
   Gearing (if applicable):       
   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.

   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.
