Hercules Stepper Motors

Extreme torque in a small package

Hercules Series motors output up to 40% more torque than standards motor of same size. This means more power, more efficiency, and more speed. Available in NEMA 23 and 34 size.
  • Our NEMA 23 sized motor produces up to 600 oz-in of holding torque.

How much more can you get out of your machine with this much torque?

How Did We Do It?

Inherently, every stepper has flux leakage which equates to torque loss. By inserting magnetic pins within the rotor, we were able to mitigate flux leakage, resulting in improved torque by up to 40%.


Standard Stepper Motors

All standard stepper motors experience some non-torque producing flux, or flux leakage

Hercules Motor

Magnet pins are located between rotor teeth. Full circumferential coverage over rotor increases focusing flux and overall torque performance
