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 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.  

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

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

DC motor drives act as the interface and power supply between a motion controller and a DC motor

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

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

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

AC motor starters are used to turn-on and turn-off electric motors and motor-controlled equipment. They use solid-state or electromechanical technologies, and are designed for single-phase or three-phase motors

DC motor starters combine a controller (most often a contactor) with overload protection, allowing a motor or motor-controlled equipment to be turned on and off

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

Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications

Electrical brushes and brush materials are used in conjunction with slip rings, commutators or other contact surfaces to maintain an electrical connection in rotary and linear sliding contact applications.
