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

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

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry

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

Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters

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

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

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

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

Motor coils are used with motors, generators, stators, and armatures

Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.

Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer

Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine

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