The circuit operates as follows. When the forward signal input of the motor drive circuit 40 receives the output of the microprocessor 30. When the signal is forwarded, the base terminal (B1) of the first transistor (Q1) is high, so that the first transistor (Q1) is 0N, and the first relay (Relayl) is operated, and the first common terminal (C0M1) and the first A normally open (N01) is turned on, at which time the power supply (+V) is from the third normally closed end (NC3) of the third relay (Relay3) to the third common end (COM3), and then the second relay (Relay2) The second common terminal (COM2) to the second normally closed end M345868 ^ (NC2) is transmitted to the second power terminal (B), and then passes through the three-wire motor and is terminated by the first power terminal (G) first relay ( The first common terminal (COM1) of the Relayl) is connected to the first normally open terminal (N01) to the ground terminal (GMD) to form a positive electrical circuit. When the reverse signal input end of the motor drive circuit 40 receives the inverted signal output by the microprocessor 30, the base terminal (B2) of the second transistor (Q2) is high, so that the second transistor (Q2) ON, and let the second relay (Relay2) and the third relay (Relay3) operate, the second common terminal (COM2) • is electrically connected to the second normally open terminal (N02), and the third common terminal (COM3) Conducted with the third normally open end (N03), at which time the power supply (+V) is transmitted from the first normally closed end (NC1) of the first relay (Relayi) to the first common end (COM1) to the first power end (G) After passing through the three-wire motor 10, the third power terminal (W) is connected to the second normally open end (N02) of the second relay (Relay 2) to the second common terminal (COM2), and then by the second common terminal (COM2) To the third common terminal of the third relay (Relay3), the third normally-open end (N03) is connected to the ground terminal (GND) to form an electrical circuit of the inversion I. - For example, please refer to Figure 4, Figure 5 and Table 1. Assume that the roll door motor M1 is a forward (down) drive motor, the limit switch LSI is a lower limit switch, and the roll door motor M2 is a reverse (rising) drive. Motor, limit switch LS2 is the upper limit switch. When the roll door 1〇〇 is in the upper limit position, the limit switch LS2 is touched, then the common terminal c2 and the normally closed end b2 are not turned on, so that the third power end (W) Since the power of the shutter motor M2 is interrupted, the motor drive circuit 40 cannot be driven to rewind (rise) the reel motor. When the motor drive circuit 40 receives the forward rotation signal, the second power terminal (B) π M345868 is connected to the power terminal (+V), and the first power terminal (G) is connected to the ground terminal (GND). When the limit switch LSI is not touched, the common terminal c1 and the normally closed end bl are turned on, so that the roll door motor M1 is driven, and the forward rotation drives the roll door 100 to descend. When the roll door 100 leaves the upper limit position, the limit switch LS2 will return to the untouched state, and its common terminal c2 and the normally closed end b2 are turned on, so that the roll door motor M2 can be controlled at any time during the lowering process. Turn up _ liter, or stop the roll door motor M1 to run. When the roll door 100 reaches the lower limit position, the limit switch LSI is activated, • the common terminal c1 and the normally closed end bl are not turned on, and the power of the second power terminal (B) and the roll door motor M1 is interrupted, so The motor drive circuit 40 drives the shutter motor M1 to reverse (rise) and stop. When the motor driving circuit 40 receives the reversal signal, the first power terminal (G) is connected to the power terminal (+V), and the third power terminal (W) is connected to the ground terminal (GND). The limit switch LS2 is not touched, and the common terminal c2 is electrically connected to the normally closed end b2. Therefore, the roll door motor M2 is driven, and the reverse rotation of the roll door I 100 is raised. When the roll door 100 leaves the lower limit position, the limit switch LSI returns to the untouched state, and its common end cl and the normally closed end bl are turned on, so that the roll door motor can be controlled at any time during the ascent process. Ml rotates (down) or stops the rolling door motor M2. However, the microprocessor 30 must know whether the three-wire motor 10 is in the forward, reverse or stop state to issue the correct forward or reverse signal. If the three-wire motor 10 is in the forward rotation state, it will also issue a reverse The transfer signal, or the reverse state, and the forward rotation signal may cause the motor drive circuit 40 to be short-circuited or the three-wire motor 10 to be burnt. Therefore, the present invention is 12 M345868 - electrically connected by the two-resistor voltage dividing circuit 50, respectively. Between the first power terminal (G) and the second power terminal (W), and between the first power terminal (G) and the third power terminal (w), the voltage divider power supply that is separated by the resistor is fed back to the The microprocessor 3 is configured to allow the microprocessor 30 to determine whether it is in a running or stopped state. When there is a voltage dividing power source between the first power terminal (G) and the second power terminal (B), it indicates that the three-wire motor is in a forward rotation state, when the first power terminal (G) and the third power terminal (W) When there is a voltage dividing power supply, it means that the three-wire motor is in the reverse direction and although there is no voltage dividing power supply, it means that it is in the stop state, and the three-wire motor is changed in forward rotation. When the inverter is reversed, or the reverse rotation is changed to the forward rotation, the microprocessor 30 stops transmitting the forward and reverse signals first, and confirms that the three-wire motor 10 stops operating, and then sends the changed forward and reverse signals, so that it is correct. The control of the three-wire motor is operated or stopped. The position is that this creation can indeed provide a design that is different from the well-known ones by the above-mentioned techniques, which can improve the overall use value, and it has not been seen or used publicly before the application, and has already complied with the new patent. It is necessary to ', _ pieces, and file a new type of patent application according to law. $, the above disclosed n system is only an embodiment of the present invention - and those skilled in the art can make other various improvements according to the above descriptions, and these changes are still within the scope of the patent of the creation of the creation. .斤介 [Simple description of the diagram] The diagram is a block diagram of the control circuit of the conventional roller door motor; the diagram is a schematic diagram of the control circuit of the 4-way one-winding motor; 13 M345868 ~ Figure 2 is the creation of the three-wire rolling door motor The control circuit block diagram; Figure 4 is a circuit diagram of the creation of the three-wire motor combined with the limit switch; and ~ Figure 5 is a schematic diagram of the motor drive circuit.
