The word Hybrid means combination or mixture. In the center of the rotor, an axial permanent magnet is provided. It is magnetized to produce a pair of poles as North N and South S as shown in the figure below. At both the end of the axial magnet the end caps are provided, which contains an equal number of teeth which are magnetized by the magnet. The figure of the cross section of the two end caps of the rotor is shown below.
Stepper Motor Basics "A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied.
A stepper motor , also known as step motor or stepping motor , is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback an open-loop controller , as long as the motor is carefully sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated. Brushed DC motors rotate continuously when DC voltage is applied to their terminals. Each pulse rotates the shaft through a fixed angle.
This lesson is a continuation of a series of lessons involved with learning about Stepper Motors and Servo Motors. Have you ever thought about how a robotic arm moves with precision or how graphic printers create accurate replications of images, or how consumable products are moved precisely around a plant floor or any other type of motion control positioning system? Together with the recently RealPars published video, What is a Stepper Motor and How it Works, and this lesson, you will learn about Stepper Motor Advantages in motion control when using different types of motors available, primarily stepper and servo motors. Selecting between a stepper motor and servo motor can be quite a challenge with the balancing of several design factors in cost considerations, torque, speed, acceleration, and drive circuitry all play an important role in selecting the best motor for your application. Torque is the tendency of a force to rotate an object about an axis, fulcrum, or pivot.
Construction Permanent Magnet Stepper Motor In this motor, the stator is of multipolar and its construction is similar to that of variable reluctance stepper motor as discussed above. It consists of slotted periphery on which stator coils are wound. It constructs of a rotor that is of permanent magnet and a stator that is of electromagnets The following figure shows the construction of a practical stepper motor:Stepper motor - Wikipedia,A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps.

Premium Membership. Learn from experienced power engineers. A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements.
Today we will discuss about stepper motor, its working, types, advantages, disadvantages with it functional area. In simple words, it is a combination of DC motor with electronics technology which allows the motor to rotate and stop at specified angle. It is mostly used in robotics where move the arm of robots at specified angle and hold there for some time and get back return after it. This is a brushless electromechanical device which is used to convert the series of electric pulses applied at their excitation winding into precisely defined step by step the mechanical shaft rotation. In others words, the stepper motor is an electromechanical device which converts electrical power into mechanical power.
A stepper motor is an electromechanical device it converts electrical power into mechanical power. Also, it is a brushless, synchronous electric motor that can divide a full rotation into an expansive number of steps. Stepper motors are similar to switched reluctance motors. The stepper motor uses the theory of operation for magnets to make the motor shaft turn a precise distance when a pulse of electricity is provided. The stator has eight poles, and the rotor has six poles.
