Features & Benefits

We've Reinvented the Step Motor


Conventional hybrid stepper motor utilizes a permanent magnet in the rotor. Our patented design uses a ring magnet in the stator instead. This drastically reduces the detent torque (unenergized drag torque) because the magnetic flux path is able to reach over the stator windings and go through only the outer edge of the rotor. Reducing detent torque improves accuracy, smooth operation and reduces noise. Best of all, modifying the magnet location does not change the dynamic torque.

Large Holow Shaft Up to 11 mm in Diameter


Conventional stepper motors cannot accommodate large diameter hollow shafts without sacrificing torque and performance. Torque is dependent on the size of the magnet placed in the rotor. A large diameter shaft reduces space available for the magnet, thus sacrificing torque.


Since we’ve moved the magnet from the rotor into the stator stack, we can accommodate a large shaft without sacrificing torque or performance.

Extreme accuracy


Z-Series motor maintains ±1.5 arc minutes error under 64x microstepping. Industry average can range from ±4.5 to ±18 arc minutes in 0.9° step motors.
Quiet Operation


By eliminating detent torque, the motor operates substantially quieter than regular hybrid stepper motor.
