Working principle of stepper motor
To make the motor shaft turn, first one electromagnet is given
power, which makes the gear’s teeth magnetically attracted to the
electromagnet’s teeth. The point when the gear’s teeth are thus
aligned to the first electromagnet, they are slightly offset from
the next electromagnet. So when the next electromagnet is turned ON
and the first is turned OFF, the gear rotates slightly to align
with the next one and from there the process is repeated. Each of
those slight rotations is called a step, with an integer number of
steps making a full rotation. In that way, the motor can be turned
by a precise. Stepper motor doesn’t rotate continuously, they
rotate in steps. There are 4 coils with a 90o angle between each
other fixed on the stator. The stepper motor connections are
determined by the way the coils are interconnected. In a stepper
motor, the coils are not connected. The motor has a 90o rotation
step with the coils being energized in a cyclic order, determining
the shaft rotation direction. The working of this motor is shown by
operating the switch. The coils are activated in series in 1-sec
intervals. The shaft rotates 90o each time the next coil is
activated. Its low-speed torque will vary directly with current.
Operation of Stepper Motor:
Stepper motors operate differently from DC brush motors, which rotate when voltage is applied to their terminals. Stepper
motors, on the other hand, effectively have multiple toothed
electromagnets arranged around a central gear-shaped piece of iron.
The electromagnets are energized by an external control circuit,
for example, a microcontroller.
