QSH 5718
new series 57 mm / NEMA23
1.8° step angle
high torque
hybrid stepper motor
These high torque two phase hybrid stepper motors are opti-
mized for microstepping and give a good fit to the TRINAMIC
family of motor controllers and drivers. They are also used in
the new 57 mm PANdrive mechatronics family.
