摘要： PROBLEM TO BE SOLVED: To make it possible to quickly and surely detect an abnormality such as the locking of rotation of a motor and the shorting of a winding and conduct a danger preventing operation to appropriately correspond to the details of the abnormality, in a small-sized electric apparatus using the motor as a load. SOLUTION: A transistor for switching 89 is serially connected to a motor 15. The detection of an abormality in the motor 15 is conducted by individually detecting the surface temperature of the transistor 89 which increases along with the increase in load current and the collector-emitter voltage. When the temperature is rising, it is determined that an accident could happen if a device is continuously used and then the driving of the motor 15 is temporarily stopped. On the other hand, when the voltage is rising, the driving of the motor 15 is constantly stopped.

摘要： PURPOSE: To promote safety of a window controller by making make-operation when insertion is detected during the break-operation of a power window, and making break-operation forcedly even when insertion is detected during the break-operation. CONSTITUTION: During the up-operation of a window with an upward control switch 2, the output of an insertion detecting section 5 is in a high state when insertion of a foreign matter is deteted. Then, the output of an AND circuit 13 and the output of an OR circuit 14 become low to make high the output of the OR circuit 15, and the window is inverted downward to operate an insertion preventing function. In that case, after the detection of insertion, a leading detecting section 9 of an insertion detected releasing switch 4 outputs trigger such as single event pulse, etc., with the insertion detected releasing switch 4. Accordingly, since an output terminal Q of a sequence circuit 8 is in a high state, the sequence circuit 11 is set, and the AND circuit 12 and OR circuit 14 are formed. The window is upped to forcedly up the window with the insertion detected releasing switch 4 after the detection of insertion.

摘要： PURPOSE: To accurately stop at a target position as quickly as possible by controlling and braking an electric motor for driving a traveling machine based on a reference speed corrected by speed deviation when the reference speed reaches a fine speed region. CONSTITUTION: A reference speed is calculated based on a reference speed pattern and a position deviation. When the reference speed reaches a fine speed region, a means 13d for calculating the amount of correction of reference speed calculates the amount of corrected reference speed based on the speed from a speed operation means 13c and the speed deviation of the reference speed. By adding the reference speed to the value, a traveling machine moves at a constant speed of the corrected reference speed until it stops at a target position. Immediately before stopping at the target position, the position deviation is calculated by a braking timing generating means 13e to control machine braking distance, thus accurately stopping at the target position as quickly as possible.

摘要： PURPOSE: To obtain a brake circuit for a single phase series commutator motor in which the cost is reduced while prolonging the service life. CONSTITUTION: The brake circuit for a single phase series commutator motor comprises a main winding MW for driving an armature M, and a brake winding BW for braking the armature M wherein the armature M is driven or braked by switching the connection of the main winding MW and the brake winding BW through a single pole double throw switch SW1. In such brake circuit, a single pole switch SW2 is disposed between the brake winding BW and a common contact X of the armature M and the main winding MW. The switches SW1, SW2 isolate a high voltage appearing between the main winding MW and the brake winding BW at the time of driving the armature M and prevent field layer short thus attaining a long service life.

摘要： PURPOSE:To let a substance be accurately positioned only by an operation control section by operating the quantity of coasting of an electric motor after a command for stopping its movement has been directed, and thereby sending a feedback pulse corresponding to the quantity of coasting to the electric motor. CONSTITUTION:When the movement command switch of a control panel 5 for either of operations is turned on, a normal or a reverse operation pulse is outputted to a motor 1 from a controller section 6 respectively. In this case, when an intended stop position is recognized by an operator, the movement command switch of the control panel 5 is turned off. At this time, position coordinates A when a switch is turned off are outputted to an operation section 10 from a position detector 4, and the values are then stored in the operation section 10. After the motor 1 has coasted, its position coordinates B are outputted to the operation section 10 as soon as the substance is suspended, an operation of A minus B is performed at once by the operation section 10, and the result of the operation is thereby feed-backed to the controller section 6. A feed-back pulse matching the aforesaid feed-back is sent to the motor 1 from the controller section 6, and control is executed in such a way that a present value by the position detector 4 coincides with the position coordinates A.
