    摘要: An AC power supply (50) supplies a full wave rectifier (51) with a positive output line (P) and a negative output line (G). A DC motor (2) is connected in series with a drive transistor (3) between the positive and negative lines (P,G). Actuating current can be supplied from the positive line (P) by closure of a switch (59) coupling the line (P) through a base resistor (61). A detecting transistor (54) connected in series with a collector circuit resistor (60) between the lines (P,G) sense the voltage at the node (N) between the motor (2) and the drive transistor (3) through a base circuit resistor (62) and latches the drive transistor (3) on unless the voltage at the node (N) disables the detecting transistor (54).

    摘要: A motor-powered opening/closing apparatus includes a circuit (Q1, R1, Q4) for detecting a constrained state of the motor (10) and deenergizing the motor (10), and a circuit (4, Q4) for detecting clamping of a foreign object between an edge of the window (2) or the door and a fixed frame (1) and stopping or reversing rotation of the motor (10). These circuits (Q1, R1,Q4,4) are independently arranged to detect clamping of the foreign object with high sensitivity while a closing force at the closed position can be kept large. The circuit (Q1, R1, Q4) for detecting a constrained state utilises motor current reversal noise to obtain a rapid response.
