Motors, Drives & Rotating Equipment

Fundamental to electromechanical components are motors and drives. Included are AC, DC, brush, brushless, and application specific motors along with related gear mechanisms, actuators, slides and synchros/resolvers.
Brush DC Motors (81 Companies)
Brush DC motors have built-in commutation, meaning that as the motor rotates, mechanical brushes automatically commutate coils on the rotor.
Brushless DC Motors (99 Companies)
Brushless DC motors use external power drive for commutation of the coils on the stator. Electromagnets in the motor do not move, instead, the permanent magnets rotate and the armature remains static. These motors are more efficient than brush DC types.
A motor having a continuous rating of less than one horsepower. Can be fuel powered but usually are AC-driven electric motors. Provide motion for small or low horsepower needs, e.g. small surgical devices, internal computer fans, pumps, etc.
Gearhead Motors (72 Companies)
Refers to a general class of AC/DC motors that are used with an integral gear box or gear head. Often found in robotics, automotive, positioning applications, etc.
Gears and Gear Mechanisms (47 Companies)
Systems of gears and mechanisms that diminish speed when power is transmitted. Gears located between motors and the machinery it drives. Gear mechanisms transmit motion in particular directions for many specific purposes.
Indexers (Stepping Motor) (26 Companies)
A stepping motor is an electrical motor driven by electrical impulses, rather than continuous voltage. The indexer creates a clock pulse that controls how often and how long the electrical impulses last. The indexer also controls the direction of motion.
Induction Motors (37 Companies)
Type of asynchronous AC motor where power is supplied to a rotating, electromagnetic device. Induction motors are choice motor for the industrial world because of their rugged construction, lack of brushes, and ability to control motor speed.
Linear Motors (45 Companies)
Generate linear force in direction of travel and eliminate transmission devices e.g. rotary motion to linear motion converter. Motors capable of high speeds, quick acceleration, and accurate positioning. Found in transportation, weapons, positioning, etc.
Linear Slides (28 Companies)
Are simple linear motion devices consisting of a stationary base and a moving carriage. Provide a guide for other industrial elements, e.g. as machining tools, assembly units, etc. and used on machine tools, medical equipment, measuring instruments, etc.
Micro Motors (21 Companies)
Miniature DC motors-some are SMDs–with length dimensions in the order of 10 mm. Used in cameras, robotics, CD-DVD players and other commercial areas. These motors can be brushless, brush, stepper type, etc.
Permanent Magnet Motors (80 Companies)
Has a permanent magnet field (stationary) and a wound armature (rotating). Its speed can be changed by varying the armature voltage. Used where variable speed is required, e.g. lawn/garden equipment, etc. Also for compressors, pumps and HVAC applications.
Piezoelectric Motors (9 Companies)
A type of electric motor based upon change in shape of a piezoelectric material when electric field is applied. These motors can be made very small and often the driving element for auto-focus mechanisms in cameras and drives in linear motion devices.
Servo Motors & Actuators (136 Companies)
A servo motor that is used in servo systems. As the input to the motor varies, the angular position of the output shaft changes. Servo actuators are linear drive mechanisms that are used in robotics, automation and other manufacturing processes.
Stepping Motors (72 Companies)
Electric motors that can divide a full rotation of the shaft into a number of discrete angular motions of uniform magnitude, or steps, rather than continuous rotation.
Synchronous Motors (36 Companies)
An AC motor distinguished by rotor spinning with coils as magnets pass at the same speed as the alternating current. Synchronous motors are used to control and improve the power factor on a local electrical grid and used in power or electrical plants.
Synchros/Resolvers (22 Companies)
Synchros/resolvers are motor-like devices containing a stator and a rotor and capable of transforming an angular position input into an electrical output. Often used in antenna rotators, angle measurement devices, positioning systems, etc.
