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 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 a cylindrical winding that is physically outside of a set of permanent magnets. The winding is not held by a slotted iron cage but is laminated together. In a slotless motor, the magnets attached to the rotor rotate. In a coreless motor, the windings rotate around the permanent magnet stator.

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.

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 an extremely precise speed reduction system that transmits power via a rotating elliptical element that engages a flexible cup that then engages an internal gear, which is typically fixed. This power transmission delivers precise angular position in very high input-to-output ratio (50:1 & up) applications.
|
| |
Worm
|
|
Right-angle drive 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.

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.
|

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).
