  • Performance Curves +


    TORQUE vs. PULSE RATE
    L/R Drive, Bipolar, 15° Step Angle

    25% Duty Cycle is obtained by a special winding or by running a standard motor at double the rated current.

    TORQUE vs. PULSE RATE
    Chopper Drive, Bipolar, 15° Step Angle

    25% Duty Cycle is obtained by a special winding or by running a standard motor at double the rated current.

    NOTE:  All chopper drive curves were created with a 5 volt motor and a 40 volt power supply.

    Ramping can increase the performance of a motor either by increasing the top speed or getting a heavier load accelerated up to speed faster.  Also, deceleration can be used to stop the motor without overshoot.

    With L/R drives peak force and speeds are reduced, using a unipolar drive will yield a further 30% force reduction.
