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

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

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

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

Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy

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

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

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

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

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

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

Rotary positioning stages are devices with tables or shafts that may be rotated to any angular position. They may be driven or simple slides.

Dynamometers are used in motor and engine testing. These devices apply braking or drag resistance to rotation, and measure torque at various speeds and power input levels
