A bipolar hybrid stepper motor Brushed DC motors rotate continuously when DC voltage is applied to their terminals. The stepper motor is known by its property of converting a train of input pulses (typically square wave pulses) into a precisely defined increment in the shaft position.
A unipolar stepper motor only operates with positive voltage, so the high and low voltages applied to the electromagnetic coils would be something like 5V and 0V. A bipolar stepper motor has two polarities, positive and negative, so its high and low voltages would be something like 2.5V and -2.5V.
Most high speed stepper motors are bipolar, however. A unipolar stepper motor follows this diagram: Since the two electromagnets have a common wire, only one power source is necessary for a unipolar stepper motor. The common wire is usually connected to ground. The 28BYJ-48 is a unipolar stepper motor, with five pins as shown:

Bipolar stepper motors. The bipolar stepper motor usually has four wires coming out of it. Unlike unipolar steppers, bipolar steppers have no common center connection. They have two independent sets of coils instead. You can distinguish them from unipolar steppers by measuring the resistance between the wires.
A stepper motor to satisfy all your robotics needs! This 4-wire bipolar stepper has 1.8° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 350mA so that it could be driven easily with an Adafruit motor shield for Arduino (or other motor driver) and a wall adapter or lead-acid battery.
May 15, 2015 · In BIPOLAR stepper motor we have phase ends and no center taps and so we will have only four terminals. The driving of this type of stepper motor is different and complex and also the driving circuit cannot be easily designed without a microcontroller. The circuit which we designed here can only be used for stepper motors of UNIPOLAR type.
