Working principle of Gear Box 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.
Not every application will benefit from a stepper motor, but in the right environment stepper motors can be ideal. First, stepper motors have full torque at standstill, and the rotation angle of the motor is proportional to the input pulse. Essentially, stepper motors offer excellent speed control, precise positioning, and repeatability of movement.
Additionally, stepper motors are highly reliable since there are no contact brushes in the motor. This minimizes mechanical failure and maximizes the operation lifespan of the motor. These motors can be used in a wide range of environments, as many different rotational speeds can be achieved because the speed is proportional to the frequency of pulse inputs.
