PERFORMANCE CURVES - SERIES 20000 STEPPER MOTOR LINEAR ACTUATOR - THRUST vs. FULL STEPS/SECOND

BIPOLAR L/R DRIVE 100% DUTY CYCLE

Stepper Motor Linear Actuator Force Curve

BIPOLAR L/R DRIVE 25% DUTY CYCLE

25% duty cycle is obtained by a special winding or by running a standard motor at double the rated voltage.
