Dynamics of Hybrid Stepper Motors
precision-machined teeth improving motor torque by redirecting magnetic fields within the stepper. Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth along its
the apparently simple mechanism rests a complex combination of laminations, coils, and magnets. Hybrid stepmotors combine the controllability of the variable reluctance motor with the higher torque of the permanent magnet or "canstack " motor. While low cost is the most no-table feature of hybrid designs, better
What are Brushless DC Motors and how do they work?
materials and gages can be utilized for different performances. High performance motors in terms of power density will use more expensive grades of materials such as Vanadium Permendur. BLDC motor rotor assembly is made of permanent magnets. Based on performance required, different magnetic materials

reality. Integration is all the rage with integrated motor/drivers and direct-drive systems changing the motor and motion-control landscape. The Inside-Out Step (IOS) motor is in tune with these trends. It's a two-phase hybrid stepper motor that uses a conventional permanent-magnet configuration
The "no-cog " motor
circuit. As permanent magnets in the rotor pass the stator teeth, they're attracted to the iron in the teeth. As the magnetic attraction jumps from tooth to tooth, the magnetic force aids or hinders rotation
