    • A system and method for bi-directional communication between a system controller and a fan controller: The system operates in two modes and there are two communication paths between the system controller and the fan controller. The first communication path provides a PWM signal the frequency of which indicates the mode in which the system is operating. During the first mode, the duty cycle of the PWM signal on the first signal path indicates the desired fan speed. In the first mode, the second communication path carries a conventional tachometer signal. In the second mode the second communication path operates as a bi-directional communications signal path between said system controller and said fan controller.

    • A fan motor speed control circuit is disclosed. The circuit includes a digital/analog converting unit and a driving unit. The digital/analog converting unit takes charge of receiving a pulse width modulation (PWM) signal and converting it into a voltage signal. The driving unit is connected with the digital/analog converting unit in series for receiving the voltage signal, while the driving unit provides a first predetermined voltage level and a second predetermined voltage level as references. The fan motor is kept to run with a low constant rotation speed when the voltage signal level is higher than the first predetermined voltage level, with a full constant rotation speed when the voltage signal level is lower than the second predetermined voltage level, and with a variable rotation speed when the voltage signal level is lower than the first predetermined voltage level and higher than the second predetermined voltage level.

    • A motor driving apparatus capable of drivingly controlling a plurality of inverter units with a single motor driving command from a motor control unit, and thereby control a large-capacity motor or the like. The motor control unit sends out a single motor driving command (torque command) S. An intermediary unit obtains motor driving commands S×A1 to S×A4 for the inverter units by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units are fed with the motor driving commands S×A1 to S×A4 individually and drive a single motor. Since the motor is driven by the total current supplied by the inverter units, the motor can generate a large torque. The motor control unit only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Hence, the motor control unit can generate and send out motor driving commands for other motors to drive them.
    • 一种电动机驱动装置,其能够通过来自电动机控制单元的单个电动机驱动指令来驱动地控制多个逆变器单元,从而控制大容量电动机等。 电机控制单元发出单个电动机驱动指令(转矩指令)S.中间单元通过将电动机驱动指令S乘以系数A 1至A 4中的每一个来获得用于逆变器单元的电动机驱动指令SxA 1至SxA 4 提前。 逆变器单元分别供给电动机驱动指令SxA 1〜SxA 4,驱动单个电动机。 由于电动机由逆变器单元提供的总电流驱动,电动机可以产生大的转矩。 电机控制单元仅需要生成单个电机驱动指令S,因此仅需要操作单个处理部件。 因此,电动机控制单元可以生成并发送用于其他电动机的电机驱动命令来驱动它们。

    • A microcomputer includes a rotation angular velocity computation section, a feedback gain determination section, and a dead time compensation amount determination section. The rotation angular velocity determination section computes the rotation angular velocity of a brushless motor. Based on the rotation angular velocity, the feedback gain determination section determines feedback gains. The dead time compensation amount determination section determines a dead time compensation amount. The greater the absolute value of the rotation angular velocity, that is, the higher the rotation speed of the brushless motor, the greater the feedback gains determined by the feedback gain determination section become, and the higher the responsivity of the feedback gains becomes. The greater the absolute value of the rotation angular velocity, the smaller the dead time compensation amount determined by the dead time compensation amount determination section becomes.
