About Stepper Motors

Stepper motors use a magnetic field to move a rotor. Stepping can be done in full step, half step or other fractional step increments. Voltage is applied to poles around the rotor. The voltage changes the polarity of each pole, and the resulting magnetic interaction between the poles and the rotor causes the rotor to move. Stepper motors provide precise positioning and ease of use, especially in low acceleration or static load applications. 

Important performance specifications to consider when searching for stepper motors include shaft speed, terminal voltage, current per phase, continuous output power, and static or holding torque.  Shaft speed is the no-load rotational speed of output shaft at rated terminal voltage.  The terminal voltage is the design DC motor voltage.  The current per phase is the maximum rated current or winding for a stepper motor.  The continuous output power is the mechanical power provided by the motor output.  Static or holding torque is the maximum torque a motor can develop to hold its rotor in a stationary position.

Products & Services Related to Stepper Motors

AC Motors
AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.  
AC Servomotors
AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors.
DC Motors
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
DC 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.
Gearmotors
Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down.
