Shakers and shock and vibration testing equipment are force generators or transducers that provide a vibration, shock or modal excitation source for testing and analysis.

DC motors are most commonly used in variable speed and torque applications.

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors.

DC servomotors are generally small and powerful for their size, and easy to control.

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

Linear motors generate force only in the direction of travel.

AC motor drives interface controllers to AC motors.
