For this type of motor, slots are progressively notched into the steel tape as it is passed from one mandrel to another and the polyphase winding is inserted [245]. 85 T [92]. 5. 6. Double-sided machine with one internal slotted stator and buried PMs. 1 — stator core with slots, 2 — PM, 3 — mild steel core (pole), 4 — nonmagnetic rotor disc. 7. Double-stator, triple-rotor AFPM brushless motor with water cooling system [55]. 1 — PM, 2 — stator core, 3 — stator winding. 5 Double-sided machines with internal coreless stator AFPM machines with coreless stators have the stator winding wound on a non-magnetic and non-conductive supporting structure or mould.

It can be used in industrial, traction and servo electromechanical drives. The motor for hoist applications shown in Fig. 1b is integrated with a sheave (drum for ropes) and brake (not shown). It is used in gearless elevators [103]. 2 Double-sided machines with internal PM disc rotor In the double-sided machine with internal PM disc rotor, the armature winding is located on two stator cores. The disc with PMs rotates between two stators. An eight-pole configuration is shown in Fig. 2. PMs are embedded or glued in a nonmagnetic rotor skeleton.

C. armature resistance skin effect coefficient for nf, is the higher harmonic rms armature current, is the higher harmonic inverter output voltage, is the rated voltage, are the stator core losses for and rated voltage. 9 Efficiency The total power losses of an AFPM machine are The efficiency is where is the mechanical output power for a motor and the electrical output power for a generator. 13. 7 Location of the armature current 51 in coordinate system. e. e. e. where and The angle is between the and armature current When the current arrows are in the opposite direction, the phasors and are reversed by 180°.
