摘要： An electric engine starting system includes a permanent magnet motor that is used to start the engine and then to generate power for powering a load while the engine is running. A disclosed system includes a first phase controlled rectifier in series with a power converter and a second phase controlled rectifier. During an engine starting operation, the first phase controlled rectifier is switched to couple the permanent magnet motor to a power source for starting the engine. Once the engine is running, the first phase controlled rectifier is switched off and the second phase controlled rectifier is switched on. The second phase control rectifier converts variable AC power from the motor into DC power. The power converter converts the DC power into an appropriate power for driving the load. One disclosed example includes a filter between the power converter and the load to ensure that the load receives a selected quality of power.

摘要： A capstan drive includes a first capstan that moves a device on a carriage and a second capstan that receives a second rotary motion to move the carriage. A first power transmission has a driven shaft coupled to the first capstan, a first drive shaft coaxial with the driven shaft to receive a first rotary motion for driving the device, and a second drive shaft coaxial with the driven shaft. A second power transmission couples the second rotary motion to the second drive shaft. The second power transmission has a drive ratio such that if there is no first rotary motion, a first cable is drawn in by the first capstan at a same rate as a second cable is drawn in by the second capstan in response to the second rotary motion.

摘要： In response to detection of a skid of drive wheels based on an increase in angular acceleration α of a rotating shaft of a motor, the control procedure of the invention refers to a map representing a variation in maximum torque Tmax against the angular acceleration α and sets torque restriction of the motor to limit the torque level of the motor to the maximum torque Tmax corresponding to a peak value of the angular acceleration α. When the torque restriction sufficiently lowers the angular acceleration α to detect convergence of the skid, the control procedure cancels the torque restriction to a certain level of the maximum torque Tmax corresponding to a torque restoration limit δ1, which is set according to the degree of the skid. The torque restoration limit δ1 (that is, the maximum torque Tmax) is cancelled in a stepwise manner by a cancellation rate and a cancellation time corresponding to an additional accelerator depression relative to an accelerator opening at the time of detection of the skid. The control procedure sets the greater cancellation rate and the shorter cancellation time with an increase in additional accelerator depression.

摘要： A fan controlling system applicable in an electronic system having a plurality of fans is disclosed. The fan-controlling system includes a first signal generating module and a second signal generating module for generating a first and a second pulse width modulation (PWM) signals according to control instructions output by the electronic system. The fan-controlling system further includes a phase-inverting module and a delay module. Therefore, PWM signals, which are delayed with a time interval one another, can be generated by the fan controlling system, so as to respectively control a plurality of fans of the electronic system, thereby avoiding the peak value of the total power signals when the fans are run from increasing instantly, and power signal for supplying the electronic system from decreasing instantly, making the electronic system run abnormally, and its stability becomes worse.
