Motor Construction


	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.

	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.
	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.

	Gearing (if applicable)
	Your choices are...
	Bevel		Bevel gear sets have intersecting axes that are commonly, but not always, perpendicular. They mate via teeth on angled edges.
	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.
	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.
	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.
	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.

	Environmental Features
	Your choices are...
	Open Frame / Frameless		Open-frame or frameless enclosures have minimal or frame-like support, but no overall casing.
	Totally Enclosed		Totally enclosed motors have an enclosure that prevents free exchange of air between the inside and the outside of the enclosure. Common ratings are TEFC (fan-cooled) and TENV (non-ventilated); this is not an airtight rating. These motors are most frequently used in potentially contaminated environments.
	Dust-proof		Dust-proof motors protect against dust infiltration with features such as total enclosure and labyrinth seals for shafts. The IP (Ingress Protection) rating for dust-proof motors is IP6x.
	Drip-proof		Drip-proof motors contain ventilation openings that are designed so that drops of liquid or solid particles falling from any angle within 15 degrees of vertical cannot enter the motor. Motors with an IP rating of IPx1 through IPx9 are considered drip-proof.
	Waterproof		There are several degrees of waterproofing applicable to motors and they are reflected in the IP rating for the motor: IPx1: Protection against vertically falling drops of water (drip-proof). IPx2: Protection against direct sprays of water up to 15 degrees from vertical. IPx3: Protection against direct sprays of water up to 60 degrees from vertical. IPx4: Protection against water sprayed from all directions. IPx5: Protected against low pressure jets of water from all directions. IPx6: Protected against high pressure jets of water from all directions. IPx7: Protected against the effects of immersion up to 1 meter. IPx8: Protected against long periods of immersion under pressure.
	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.
