Stepper motor

The stepper motor is a drive for high-precision positioning tasks. With each pulse, the axis of a stepper motor rotates by a defined angle. With a fast sequence of pulses, the stepping movement becomes continuous rotary movement. The following factors must be taken into account when selecting the stepper motor:

• Connection type (4, 6, or 8 wire connection)

• Number of phases (2-phase)

• Torque characteristics as a function of speed

• Motor current as a function of speed

• Winding resistance or motor inductance
