The hybrid stepper that thinks it's a permanent magnet motor

>They are therefore suitable for retrofitting or for use in equipment standardised for PM style flanges where there is a requirement for the higher performance provided by hybrid motors.

>Two ranges are offered. The 16HF is a replacement for Nema size 42 PM stepper motors, but with a step angle as small as 0.9 degrees and a holding torque of 7.5 Ncm. The 10HF range is a replacement for Nema size 25 PM steppers, with a step angle of 3.75 degrees. Two models are available in this range, with body lengths of only 18 or 22 mm and holding torques of 1.2 or 1.9 Ncm respectively.

>Generally speaking, hybrid stepper motors are more expensive than PM models, but have the advantages of higher precision, better reproducibility, greater acceleration, quieter operation and longer lifetimes.
