Hybrid Stepper Motor Diagram

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.

Hybrid stepper motor diagram.

Hybrid stepper motor this is in fact a pm stepper motor with constructional features of toothed and stacked rotor adopted from the variable reluctance motor. Variable reluctance stepper motor. Hybrid synchronous stepper motor. There is a.

The magnet is axially magnetized meaning in the diagram to the right the top half is a north pole and the bottom half is a south pole. Hybrid stepper motors combine the magnet from the permanent magnet and the teeth from the variable reluctance motors. Servo motor types construction working applications what is a stepper motor. The stator has only one set of winding excited poles which interact with the two rotor stacks.

Hybrid stepper motors are named because they use a combination of permanent magnet pm and variable reluctance vr. Unlike a brushless dc motor which rotates continuously when a fixed dc voltage is applied to it a step motor rotates in discrete step angles the stepper motor can be controlled with or without feedback. The shaft of the motor rotates through a fixed angle for each discrete pulse. 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.

The permanent magnet is placed axially along the rotor in form of an annular cylinder over. Stepper motor is a brushless electromechanical device which converts the train of electric pulses applied at their excitation windings into precisely defined step by step mechanical shaft rotation.
