Permanent Magnet Stepper Motor Diagram. The interaction between the axial current carrying rotor conductors and the magnetic flux produced by the permanent magnet results in the generation of the torque. The circuit diagram of the pmdc is shown below.
The working principle of the hybrid stepper motor is similar to the permanent magnet motor. The permanent magnet design motor is perhaps the most common among several types of stepper motors. Crossectional diagram of two phase permanent stepper motor.
The other stator is then energized in the sequence so that the rotor moves and aligns itself to the new magnetic field.
The interaction between the axial current carrying rotor conductors and the magnetic flux produced by the permanent magnet results in the generation of the torque. In the above motor diagram it has two phases four poles and six tooth rotor. The working principle of the hybrid stepper motor is similar to the permanent magnet motor. 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.
