DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors

AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.  

Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications

Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down

Linear motors generate force only in the direction of travel. They are capable of extremely high speeds, quick acceleration, and accurate positioning

Motor and generator winding services suppliers specialize in producing custom motors, generators and custom windings per customer specifications, as well as companies that specialize in motor repair and refurbishing. 

DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors

AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors

Voice coil actuators and motors generate force when subjected to an electrical current or magnetic field. The coil within the motor is the only moving component, allowing for high speed motion and accurate positioning

Motor parts and accessories include products such as motor seals, commutators, laminations or laminated cores, armatures, carbon brushes, and contacts

Piezoelectric motors use a piezoelectric ceramic element to produce ultrasonic vibrations of an appropriate type in a stator structure. The consequent movement can either be rotational or linear depending on the design of the structure

Electrical winding services fabricate custom-wound assemblies for a wide range of applications, including automotive, avionics, motor, transformer, medical instrumentation and power generation applications

Electric actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level

Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors

AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals
