摘要： PROBLEM TO BE SOLVED: To provide a vacuum cleaner being inexpensive and simple but highly precise in detection, prediction of remaining life of an electric motor from the detection result, and informing of the result without providing a bypass filter for extracting noise components, without requiring integration of a value detected by an A/D converter with an integrator, or without requiring a high conversion speed of the A/D converter when detecting motor current with the A/D converter.
SOLUTION: An output of a current detecting means 31 for measuring the motor current is sampled by an A/D converter 33 for a prescribed number of times, for example, just once from a zero cross of commercial power supply voltage every half cycle of a commercial power 1 at a prescribed timing T so as to measure a motor current value at a prescribed phase angle without sampling noise components only. A remaining life of an electric motor 2 is predicted from a difference between the last data and the previous data of a detected value of the sampled current and size of a determination level to notify of information on the life.

摘要翻译：要解决的问题：提供一种廉价且简单但高度精确的检测的真空吸尘器，从检测结果预测电动机的剩余寿命，并且在不提供用于提取噪声分量的旁路过滤器的情况下通知结果，而不需要将由A / D转换器检测到的值与积分器进行积分，或者当用A / D转换器检测电动机电流时，不需要A / D转换器的高转换速度。
解决方案：用于测量电动机电流的电流检测装置31的输出由A / D转换器33采样一次规定次数，例如，每半年从商业电源电压的零交叉一次以规定的定时T对商用电源1进行循环，以便仅在规定的相位角测量电动机电流值，而不对噪声成分进行采样。电动机2的剩余寿命是根据最后数据与采样电流的检测值和确定电平的大小的先前数据之间的差来预测的，以通知有关使用寿命的信息。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a motor control device, along with a vacuum cleaner and hand dryer, capable of detecting generation of spark using a simple structure with high accuracy, and controls a motor so as to prevent smoking and ignition due to overheat on generating abnormal spark. SOLUTION: The motor control device includes a driving means 5 for controlling the drive of the motor 2 having a commutator and a brush, a spark-detection means 3 for detecting a current in the motor 2, and a spark-decision means 4 for determining abnormal conditions in spark from the output of the spark-detection means 3. The spark-decision means 4 gets a difference between the maximum and the minimum of the current in the motor 2 within a predetermined period of time, determines whether the difference is larger than a predetermined spark-determining level, and determines the abnormal conditions in the spark in accordance with the number of times that the difference exceeds the spark-determining level. The driving means 5 controls the motor 2 in accordance with the output of the spark-decision means 4. COPYRIGHT: (C)2011,JPO&INPIT

SOLUTION: The output of a current-detecting means 31 for measuring motor current is sampled by the A/D converter 33 for the prescribed number of times, for example, once, with a prescribed timing T1 from zero cross of commercial power voltage at each half cycle of commercial power so that the motor current value in a prescribed phase angle is measured, and will not extract only the noise component. Abnormality of sparks is decided from the size of the difference between a maximum value and a minimum value, within a prescribed time of the detection value of sampled current, so that a motor 2 is controlled.
