摘要： A device includes an FET 206 interposed between one end of a motor 201 and a positive electrode of a battery EB; a diode 203 for circulating an electric current so as to flow through the motor 201 after the switching means is turned off, the electric current is the same as that which has flown through the motor 201 before the switch 220 is turned off; a shunt 203a, differential amplifier 203b, and a low-pass filter 203c as means for detecting a value of an electric current flowing to the motor 210; and a controller 250 for turning on and off the switching means by the PWM control, so that the value of the electric current detected by the current detection means coincides with a target value. The controller 250 sets a very small value as the target value when the motor is rotated by inertia thereof, and supplying the electric current of the small target value to the motor 201. As a result, it is possible to protect the FET for actuating the motor in an auxiliary motor-equipped bicycle without addition of structural elements at a low cost.

摘要： At Step Sb3, a duty factor, which was calculated at Step Sb2 on the basis of a data for a feed-back control, is compared with a limit value of the duty factor. If the duty factor is less than the limit value, a pulse for the PWM control is modulated to have the calculated duty factor at Step Sb4. If the duty factor is greater than the limit value, the pulse for the PWM control is modulated to have the duty factor of the limit value at Step Sb5. Accordingly, the duty factor provided for a current value instruction is not in excess of the limit value, so that the secondary battery is prevented from discharging overcurrent in excess of the limit current which can be discharged from the secondary battery. Accordingly, although the capacitance of the secondary battery is not large, the lifetime of the secondary battery is prevented from being shortened.
摘要翻译：在步骤Sb3中，将基于反馈控制的数据的步骤Sb2计算出的占空系数与占空系数的极限值进行比较。如果占空系数小于极限值，则在步骤Sb4中调制用于PWM控制的脉冲，使其具有计算的占空系数。如果占空系数大于极限值，则在步骤Sb5中PWM控制的脉冲被调制为具有极限值的占空系数。因此，提供给当前值指令的占空系数不超过限制值，从而防止二次电池的过电流超过可从二次电池放电的极限电流。因此，尽管二次电池的电容不大，但是防止二次电池的寿命缩短。

摘要： A lubricating system for a machine such as a two-cycle internal combustion engine including a reciprocating pump that pumps a finite amount of lubricant during a single pumping stroke and a stepper motor for operating the pump through incremental phases of movement each less than a stroke. The lubricant requirements of the machine are determined and the driving increments are adjusted so as to provide a pumping stroke when the lubricant consumption of the machine reaches the output of the pump. Various arrangements of stepper motors and control arrangements are disclosed for controlling the amount and timing of the lubricate delivery.
