A stepper motor (or step motor) is a brushless, electric motor that can divide a full rotation into a large number of steps. The motor's position can be controlled precisely without any feedback mechanism as long as the motor is carefully sized to the application.

Stepper motors are often used in conjunction with mechanisms such as gears to translate rotational movement to linear displacement applications.

Stepper motors are similar to switched reluctance motors – very large stepping motors with a reduced pole count, and generally are closed-loop commutated.

Oriental Motor U.S.A. Corp. offers motion control products available, ranging from compact AC gearmotors and stepping motor systems, to brushless speed control systems, to linear and rotary actuators providing linear and rotational motion and a full line of cooling fans.

Superior Electric has been manufacturing and marketing voltage control and conditioning equipment since 1938. Product offering is divided into two major groups: Voltage Control Components and Power Quality Solutions.
