  • Neo magnets boost fuel economy
    A disassembled ECF motor has four new injection-molded Neo arcs installed (arrows), and the armature winding removed in preparation for rewinding. Permanent-magnet performance is measured by a demagnetization characteristic. The standard ceramic ferrite magnet has the lowest magnetic properties
  • How to speed up dc motor selection
    increases the winding resistance. Similarly, decreasing winding resistance with a large diameter conductor lowers the torque constant because the armature slot accommodates fewer turns. The relationship between torque constant and armature resistance is a function of the root of the resistance. Choosing
  • Linear AC Motors
    stator becomes a linear stator, defining a single-sided linear induction motor (SLIM). Likewise, if the circular stator is cut into two sections and flattened, the motor becomes a double-sided linear induction motor (DLIM). The DLIM and SLIM both require a two or three-phase stator (primary) winding
  • Coreless DC Motors
    in conventional motors is caused primarily by the release of stored energy in the armature inductance upon commutation. Excessive arcing produces electrical noise and reduces the life of brushes. Coreless motors are classified by rotor shapes as cylindrical or disc. Cylindrical rotors are further divided
