Further, the microprocessor is programmed to (i) compare the armature voltage reference signal to the measured armature voltage signal and generate an armature voltage error signal based on the comparison; (ii) generate the field current correction signal as a function of the armature voltage error signal; (iii) generate an armature-to-field current check function, wherein the check function defines a set of armature current to field current ratio values as a function of armature current; (iv) calculate a ratio of the measured armature current signal to the field current setpoint signal to establish an operating ratio value, (v) compare the operating ratio value to a corresponding armature current to field current ratio value of the armature-to-field current check function, and (vi) establish the field current de-boost signal, wherein the magnitude of the field current de-boost signal is a function of the measured armature current signal and the comparison of the operating ratio value to the corresponding ratio value.

摘要： A motor driving apparatus PWM-controls a DC voltage from a rectifying unit according to a rotation speed setting information, and drives a motor by voltage pulse chooped by PWM. The rectifying unit is controlled so that a full-wave rectification is performed when the motor runs at a rotation speed below a prescribed rotation speed and a voltage-doubler rectification is performed when the motor runs at a rotation speed above the prescribed rotation speed. On the other hand, in case a motor drives a compressor of an air-conditioning system, the rectifying unit is controlled so that the full-wave rectification is performed when the air-conditioning system is a cooling operation and the voltage-doubler rectification is performed when the air-conditioning system is a heating operation. When the rectifying unit is controlled for the full-wave rectification, even if a width of voltage pulse given to the motor is decreased, a voltage value of the voltage pulse is half as compared with the voltage-doubler rectification. Hence, since a motor current is small and its current variation is also small, a hysteresis loop due to a variation in magnetic flux becomes small and an iron loss is reduced. When the rectifying unit is controlled for the voltage-doubler rectification, since a DC voltage which is the double of that of the full-wave rictification is supplied, the motor capacity can be increased.
摘要翻译：电动机驱动装置根据转速设定信息PWM控制来自整流单元的直流电压，并通过PWM选择的电压脉冲驱动电动机。控制整流单元，使得当电机以低于规定转速的转速运行时进行全波整流，并且当电动机以高于规定转速的转速运行时进行倍压整流。另一方面，在电动机驱动空调系统的压缩机的情况下，对整流单元进行控制，使得在空调系统为制冷运转时进行全波整流，并且电压倍增器整流为当空调系统是供暖操作时执行。当整流单元被控制为全波整流时，即使给予电动机的电压脉冲的宽度减小，电压脉冲的电压值与倍压器整流相比也是一半。因此，由于电动机电流小，电流变化也小，所以由于磁通量的变化引起的磁滞回线变小，铁损也降低。当整流单元被控制用于倍压整流时，由于提供了与全波基准的直流电压相同的直流电压，所以可以增大电机容量。

摘要： A microprocessor based control system generates optimal field and armature currents for a separately excited DC motor. The current levels for the field and armature coils are set by feedback control. Armature and field current setpoints are established in accordance with tabulated values selected for providing a required torque and speed in an optimal fashion. A table of corresponding values of armature voltage is also maintained. If the actual armature voltage is below the calculated value, then the field current setpoint is boosted by an amount sufficient to optimize output torque.

摘要： A direct current (DC) electrical motor system includes a DC electrical motor having energy conversion armature windings conducting a first electric current, and an electromagnetic field windings conducting a second electric current. The system also includes means to maintain the magnitude of the second electric current in the electromagnetic field windings at a substantially constant ratio of the magnitude of the first electric current in the energy conversion armature windings. Thus, the magnitude of the ampere-turn strength of the electromagnetic field of the motor is substantially always a ratio of the magnitude of the electric current in the energy conversion armature winding circuit of the motor, and the DC electrical motor of this invention performs substantially the same as a conventional series wound DC electrical motor. Also included in the DC electrical motor system are means to selectively impose one or more minimum magnitudes of current below which the second current in the electromagnetic field windings cannot substantially decrease in order to limit the maximum rotational speed of the DC electrical motor of this invention. The system also includes selective means to variably control the magnitude of the second electric current in the electromagnetic field windings independently of the magnitude of the first electric current in the energy conversion armature windings in order to control the performance of the system of this invention as a DC electric generator.
