Hybrid Stepper Motor

This is the original stepper motor.  It is still widely used today.  Due to it's low rotor inertia, it can actually run at higher speeds and more torque than the high torque motors listed in the row below.  The cost of this motor is slightly lower than the high torque motors.

Hybrid High Torque Stepper Motor

This is the most common type of stepper motor.  They have a square lamination structure that allows them to have a higher power density then round body style.  This stepper motor construction has the highest torque density of all stepper motors.

Permanent Magnet Stepper Motor

This is the least expensive stepper motor available.  They are also know as 'tin can' stepper motors.  They have lower torque to go along with the lower cost.  The loads are also considerably less then the hybrid stepper motors.

Permanent Magnet Stepper Motor with Spur Gearbox

This is the least expensive geared stepper motor available.  They are also know as 'tin can' stepper motors or geared steppers.  They have lower torque to go along with the lower cost.  The loads are also considerably less then the hybrid stepper gearmotors.

Hybrid Stepper Motor with Spur Gearbox

These motors can range in sizes from NEMA 17 to NEMA 34.  Sometimes this stepper motor and spur gearbox is call a gearmotor.

Linear Actuators

These motors can range in sizes from 8mm in diameter up to NEMA 34.  Sometimes this stepper motor and spur gearbox is call a gearmotor.
