This is because of the gears that are connected between the motor and output shaft, these gears help in increasing the torque.Īnother important data to notice is the Stride Angle: 5.625°/64. This means the shaft that you see outside will make one complete rotation only if the motor inside rotates for 64 times. Then, we also know that it is a four phase stepper motor since it had four coils in it. First we know that it is a 5V Stepper motor since we energize the Red wire with 5V.
EMU8086 STEPPER MOTOR FULL
That is a head full of information, but we need to look at few important ones to know what type of stepper we are using so that we can program it efficiently. Let us look at some of the important technical data obtained from the datasheet of this motor in the picture below. There is no technical reason for this motor for being named so maybe we should dive much deeper into it. So now, why is this motor called the 28-BYJ48? Seriously!!! I don’t know. We use a microcontroller like Arduino energize these coils in a particular sequence and make the motor perform the required number of steps. The Red wires will be supplied with +5V and the remaining four wires will be pulled to ground for triggering the respective coil. There are four coils which have to be energized in a particular sequence. Let us take a look at the coils present inside the motor to know exactly know from where these wires come from.Īs you can see the motor has Unipolar 5-lead coil arrangement. When each coil is being energized the motor takes a step and a sequence of energization will make the motor take continuous steps, thus making it to rotate. These motors have a sequence of coils present in them and these coils have to be energized in a particular fashion to make the motor rotate. Meaning, they will move only one step at a time. First of all steppers motors do not rotate, they step and so they also known as step motors. Okay, so unlike a normal DC motor this one has five wires of all fancy colors coming out of it and why is it so? To understand this we should first know how a stepper works and what its specialty is.
