Our on-line Permanent Magnet supplies store (http://xf-magnet.com) consists largely of neodymium rare earth magnets with 150 sizes of discs, cylinders (rods), blocks (rectangles), squares, cubes and rings. Their uses vary from tripping sensors, holding or lifting objects and even levitation....
Permanent Magnets are object that contain a level of magnetism. Magnetism refers to the ability to attract or repel other magnets. Something is considered magnetic when the electrons of the object align themselves so that they all point in the same direction.
Types of Permanent...

DC vs AC Motors
DC or direct current motors work in particular situations whereby the speed of the motor needs to be externally controlled. On the other hand AC or alternating current electric motors are used in a completely different process drawing upon the kind of ac motor being used.
DC...
How to Glue Brushless Motor Magnets - When building models, be they planes or boats or robots, the ubiquitous motor of choice is the brushless motor. The reason for this is power and longer run times. A motor with brushes has current running through them into the center of the motor. After a time,...
combine the operating principles of the reluctance instance variable with permanent magnet stepper motors. The rotor shaft has one or more pairs of layered sheets, the many teeth along its outer diameter. A permanent magnet between each laminated stack creates a pair of North and South poles along...
Conventional hybrid stepper motors are rarely used in closed systems, because torque drops rapidly as current increases above the maximum torque point - put it outside typical control limits. The stepper motor torque decreases as speed increases. If speeding, losing hybrids positional accuracy by...
