    • The motor assembly comprises a bidirectional stepping motor having a coil, a stator provided with a central opening in which is mounted for rotation about an axis a rotor including a permanent magnet which is magnetized along an axis of magnetization, and positioning means for defining two rest positions of the rotor in which the axis of magnetization of the magnet is directed along an axis of static equilibrium. The stator is formed of two pole pieces which partly surround the rotor and are interconnected by two intermediate parts and by four isthmuses in such a manner that the intermediate parts are intersected by the axis of static equilibrium and that two isthmuses which are opposite each other in relation to the axis of rotation of the rotor are located in one direction making with the axis of static equilibrium an angle of between 30.degree. and 60.degree.. Two of these isthmuses which are located in the same direction have a width such that they are very rapidly saturated with magnetic flux when the coil produces in the stator, in response to a driving pulse, a magnetic field which enables the rotor to be made to turn in one direction, while the other two isthmuses have a width two to four times greater so that, when the coil generates a magnetic field which causes the rotor to turn in the other direction, the wide isthmuses, or, in this case again the narrow isthmuses become saturated, but less rapidly, so as to obtain a difference in the form of the current in the coil which enables a control device associated with the motor to determine the direction in which the rotor prepares to turn in response to a driving pulse and to avoid any unintentional reversal of the direction of rotation of the motor.
    • 电动机组件包括具有线圈的双向步进电机,设置有中心开口的定子,其中安装有用于围绕轴旋转的转子,转子包括沿着磁化轴线被磁化的永磁体;以及定位装置,用于限定两个静止 转子的位置,其中磁体的磁化轴线沿着静态平衡轴线引导。 定子由两个极片组成,其部分围绕转子并且通过两个中间部分和四个峡部以这样一种方式相互连接,使得中间部分与静态平衡轴线相交,并且两个相互相对的平台 与转子轴线的关系位于一个方向上,使静止平衡轴的角度在30°和60°之间。 位于相同方向的这些峡谷中的两个具有这样的宽度,使得当线圈在定子中响应于驱动脉冲产生磁通时,它们被磁通非常快地饱和,使得能够使转子 在一个方向上转动,而另外两个峡谷的宽度是二至四倍的宽度,使得当线圈产生使得转子在另一个方向上转动的磁场时,广泛的峡谷,或者在这种情况下再次 狭窄的峡部变得饱和,但不太快,以便获得线圈中的电流形式的差异,这使得与电动机相关联的控制装置能够响应于驱动脉冲确定转子准备转向的方向 并避免电机旋转方向的任何无意的反转。

    • The rotor of a brushless DC motor is monitored continuously, and successive positions thereof are encoded in the form of digital counts. The count is continuously converted to analog form, and is compared with an analog reference signal, to determine the position error, and hence the speed error, or the motor relative to the desired constant speed reference. The error differential is suitably converted back to digital form to provide the motor power/drive amplifiers with sufficient electrical drive for the degree of correction which must be made. The digital position count from the counter is also coupled to a memory, which maintains in storage representations of position, and torque characteristics of the motor. Hence, based on these stored quantities and upon the actual motor parameters as exemplified by the present position, the memory issues control signals, that is timing and directional commands for correction of the motor speed.
    • 无刷直流电动机的转子被连续监测,其连续位置以数字计数的形式进行编码。 计数继续转换为模拟形式,并与模拟参考信号进行比较,以确定相对于所需恒速参考值的位置误差,从而确定速度误差或电机。 误差差被适当地转换回数字形式,以便为必须进行校正的程度提供具有足够电驱动的电机功率/驱动放大器。 来自计数器的数字位置计数还耦合到存储器,其保持电机的位置和扭矩特性的存储表示。 因此,基于这些存储的量和根据当前位置示例的实际电动机参数,存储器发出控制信号,即用于校正电动机速度的定时和定向指令。
