What is the difference between a bipolar and unipolar AC stepping motor ?
AC stepping motors are widely used in various applications such as robotics, CNC machines, and automation systems. They convert electrical pulses into mechanical movements with high precision and repeatability. There are two main types of AC stepping motors: bipolar and unipolar. This article will discuss the differences between these two types of motors. Bipolar AC stepping motors have two windings that are connected in series or parallel. Each winding is energized by an alternating current (AC) source, which creates a magnetic field. The direction of the magnetic field depends on the polarity of the current flowing through the windings. By changing the polarity of the current flowing through the windings, the direction of rotation can be reversed. Bipolar AC stepping motors have several advantages over unipolar motors, including higher torque output at lower speeds, better heat dissipation due to larger surface area of the windings, and more efficient use of electrical energy due to lower resistance of the windings. Unipolar AC stepping motors have only one winding that is energized by an alternating current (AC) source. The direction of the magnetic field created by this winding is always the same, regardless of the polarity of the current flowing through it. Unlike bipolar motors, unipolar motors cannot change the direction of rotation without additional hardware. Unipolar AC stepping motors have some advantages over bipolar motors, including simpler control circuitry since only one winding needs to be controlled, lower cost due to fewer components required for operation, and smaller size and weight, making them suitable for compact applications. In conclusion, bipolar and unipolar AC stepping motors differ in terms of their number of windings, ability to reverse direction, torque output, heat dissipation, efficiency, control circuitry complexity, cost, and size/weight. Depending on the specific requirements of your application, you may choose either type of motor based on these factors.
