The rotating magnetic field will induce voltages in both the stator and rotor windings. When the rotating magnetic field is aligned with the magnetic axis of phase as (i.e., θ=0°) as shown in Fig. 3.17, the flux density distribution in the air gap can be expressed as Sign in to do...
Concentrated windings enclose the stator poles and cause magnetization in the radial–circumferential plane of the motor. 永久磁铁在电动子核心在一个轴向方向被埋置并且被磁化。 二个电动子核心由一半偏移电动子牙沥青,即,北极齿细密对一个南极齿细密空白被排 [translate] ...
of the windings provides difficulties as they are progressively switched, since it limits the rate of increase of the current upon energization and the rate at which magnetic energy can be dispersed when no longer required, particularly if excessive potentials are not be induced in the windings. ...

Since the cogging torque is reduced in the way described above while the teeth are not displaced, the winding operation of windings can be simplified. Furthermore, since the productivity in punching out cores can be increased and the cores are grouped into the plurality of blocks, the productivi...
Assembly of electric motors requires that a rotor be mounted for rotation relative to a stator so that magnets on the rotor are generally aligned with one or more windings on the stator. Conventionally, this is done by mounting a shaft of the rotor on a frame which is attached to the stat...
Another common winding arrangement is referred to as a “concentric winding.” In this type of arrangement, coils within a group are organized concentrically, such that sides of each coil will be separated by a different number of slot positions. “Lap windings” and “concentric windings” each...
As a prime mover, such as a steam turbine, a gas turbine, or a drive belt from an automotive internal combustion engine, rotates the rotor assembly, the magnetic field of the rotor assembly passes through the stator windings, inducing alternating electrical currents in the stator windings in a...
2, each stator tooth 24 and stator coil 28 will hereinafter be referred to as a “pole” 32. Each pole 32 is preferably wound separately to maximize the number of windings within a given slot volume, sometimes referred to as slot fill, thereby optimizing the performance of the electric ...
