摘要： PROBLEM TO BE SOLVED: To favorably prevent heat damage to a driver in the mechatronic structure of a motor. SOLUTION: A motor is integrally provided with a driver, and is operated at a rotational speed according to an external ECU command value N1. When the temperature of the driver is raised by heat from the motor and exceeds a first predetermined value T1, the rotational speed command value is changed to a lower one Nd. When an external command value N3 lower than Nd is inputted while the rotational speed lowers to a second predetermined value T2, at which the operation may be returned to normal operation, the command value is changed to N3 to lower the temperature. When an external command value N1 higher than Nd is inputted, the motor is operated at Nd to lower the temperature. When the temperature detection value lowers to the second predetermined value T2, the operation is returned to normal operation. Thus, even when temperature rise occurs in the driver due to heat from the motor, driving of the motor is not stopped. Therefore, it is possible to eliminate troublesomeness associated with recovery from motor drive stop. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：有利地防止电机的机电结构中的驾驶员的热损伤。解决方案：电动机一体地设置有驱动器，并且以根据外部ECU命令值N1的转速进行操作。当驾驶员的温度由电动机的热量升高超过第一预定值T1时，转速指令值变为较低的一个Nd。当转速降低到第二预定值T2时输入低于Nd的外部指令值N3，在该操作可以恢复正常操作的情况下，命令值变为N3以降低温度。当输入高于Nd的外部指令值N1时，电动机以Nd操作以降低温度。当温度检测值降低到第二预定值T2时，操作返回到正常操作。因此，即使由于来自电动机的热而在驾驶员中发生温度升高，电动机的驱动也不会停止。因此，可以消除与电机驱动停止恢复相关的麻烦。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and method for controlling motor rotation, which increase the response speed of a motor while suppressing a rush current value even if the rotational speed of the motor is sharply increased when the motor operates steadily. SOLUTION: The control circuit 30 of the apparatus 1 for controlling motor rotation includes: an output duty increase determination unit 11 for determining whether a command duty ratio has a value to increase the rotational speed of a brushless motor 2 with respect to an output duty ratio or not; an initial output-duty output determination unit 13 for determining whether the command duty ratio is greater than an initial output duty ratio or not; and a Δ duty table 18 indicating association between predetermined control time and a Δ duty ratio. When the output duty increase determination unit 11 determines that the command duty ratio has the value to increase the rotational speed of the brushless motor 2, the Δ duty ratio is obtained by referring to the predetermined control time and the Δ duty table 18 to change the output duty ratio based on the obtained Δ duty ratio.

Furthermore, tapered holes 9a are bored in the side of the case 5b opposite to the direction in which the leads 6a penetrate. For instance, when two or more elements are fixed to the cabinet, the leads of the elements can be kept in a state in which they are positioned by the corresponding guide holes. By this setup, the extension ends of the leads can be aligned with the lead insertion holes of the board 4, so that an assembly of inserting the extension ends of the leads into the lead insertion holes of the board 4 can be easily carried out. The guide holes are formed of a part of the connector 5, so that an assembly operation can be easily carried out by guiding the leads with the guide holes without preparing additional components.

摘要： PROBLEM TO BE SOLVED: To continue operation even if one of the magnetic pole sensors of a brushless motor breaks down. SOLUTION: The driver for brushless motor comprises an operating section 4a for outputting a PWM signal to a motor 2, a fault detecting section 4c for outputting a fault detection signal to the operating section when any one of Hall ICs 7u, 7v and 7w breaks down, and a section 4d for generating a false signal substituting for the phase signal of the broken Hall IC, and can perform normal control using the false signal upon occurrence of failure. Since rotation can be continued even without stop operation, handleability is improved and the failure can be dealt with after the motor is driven to a standby position as the initial state by means of an automatic machine.
