The control system , however , constantly anticipates the rotor 's movement and switches the current between windings so as to stop the rotor settling into its preferred alignment .
当转子的在运动时,控制系统会一直参与其中并变换线圈中的电流以防止转子停留在最适宜的位置。
Its primary windings reside in a stationary steel casing ( the stator ) and and secondary conductors are attached to an inner shaft ( the rotor ) .
其主绕组固定在静止的铁模中(定子)而次级导体被镶在里面的轴承上(转子)。
Traditionally , this current reversal was achieved with a rotary switch known as a commutator , which transmitted electricity to the windings through brushes that made contact with conductive strips which passed under them as the rotor turned .
The motor works by the periodic reversal of the current running through these windings .
电动机的工作原理是流经线圈的电流方向的周期性改变。
Modern ac induction motors usually have three ( or more ) sets of stator windings , which smooths things out and allows more torque to be generated .
现代交流感应发动机通常有三组(或更多)定子线圈,使各程序平稳,并允许生成更多扭转力。
Modern induction motors usually have three ( or more ) sets of stator windings , each using a different phase of the alternating current being applied .
现代的感应电动机通常具有三组(或者更多)的定子绕组,每组各自使用不同相位的交流电来驱动。
Over the past year , the price of neodymium has quadrupled , as electric motors and generators that use permanent magnets instead of electromagnetic windings in their rotors have proliferated .
