The aboved speed/torque curve is based on prostepper's test
conditions. When the driving conditions change, the dynamic torque
changes too.
The related current indicated in the specification is an effective
value, please adjust the driver's current below the ralted current.

Please note the outline shows a dual-shaft motor.
The single shaft motor does not have the blue part shaft and the *
mark hole demensions.
Features of prosteppers’ stepping motor
Accurate Position Control
The angular displacement of the stepping motor can be precisely
controlled by the number of electric pulses. Angle accuracy can be
controlled within ±0.09゜without any feedback devices.
Forward/Reverse Rotation, Pause and Hold
The forward/reverse rotation of the stepper motor can be controlled
by the input sequence of the controlled electric pulses.
In case of a stepper motor lock (the motor winding is energized,
there is no external electric pulse command), the stepper motor can
still maintain a certain torgue output.
Longer life
Stepper motor is a mechanical structure, which does not need to be
commutated by brush and Hall sensor, thus reducing the probability
of failure and increasing the motor life. Stepping motor life
usually determined by the life of the bearing.
