Abstract
This invention relates to a permanent magnetic motor with two functions of DC electromotion and AC generation especially used in block identification and protection of the motor and taking controlling switch of a controllable switch with a time delay comparator as the character.
Description
A kind of motor protective circuit that the present invention proposes relates to the magneto with direct current drive and two kinds of functions of alternative electric generation.
In recent years, on miniature gasoline engine, reduce volume for saving the space, adopted and had direct current drive and two kinds of functions of alternative electric generation in the magneto of one, claim again to start and generating integrated magneto, to replace the direct current starter motor and the alternating current generator of original partial installation, this startup and generating integrated magneto are directly installed on the engine crankshaft end usually, without speed change, directly drive bent axle and rotate ato unit, because the direct Drive Structure of this not speed change makes the resistance of start increase, starting is quickened slowly, even makes motor rotation blockage and jeopardize motor safety.
The purpose of a kind of motor protective circuit that the present invention proposes is when startup and generating integrated magneto generation stall the time, can protect effectively.
The purpose of a kind of motor protective circuit that the present invention proposes is achieved in that a termination power positive pole of gate-controlled switch (1); another termination of gate-controlled switch (1) starts and an end of generating integrated magneto (2) and an end of delayer (A); start and the other end of generating integrated magneto (2) and another termination power cathode of delayer (A) the output (a of delayer (A)
0) meet the input (b of comparator (B)
1), the input (b of comparator (B)
2) connect and start and generating integrated magneto turn signal (v
i), the output (b of comparator (B)
0) meet the control end (k of gate-controlled switch (1)
i).If the time-delay stage of delayer (A), its output (a
0) be electronegative potential, its output (a when delayer (A) time-delay finishes
0) be high potential; When if startup and generating integrated magneto (2) rotate, its turn signal (v
i) be high potential, when startup and generating integrated magneto (2) stall, its turn signal (v
i) be electronegative potential; If the control end (k of gate-controlled switch (1)
i) when being high potential, gate-controlled switch (1) is opened; If only work as the input (b of comparator (B)
1) be high potential, the input (b of comparator (B)
2) when being electronegative potential, the output (b of comparator (B)
0) be high potential.When engine need start, gate-controlled switch (1) is closed to be connected, and startup and generating integrated magneto (2) begin to rotate its turn signal (v
i) be high potential, what this high potential signal was delivered to comparator (B) changes end (b over to
2), simultaneously, delayer (A) trigger, at this moment, the output (a of delayer (A)
0) be electronegative potential, so, the output (b of comparator (B)
0) be electronegative potential, it is constant that gate-controlled switch (1) is kept closed on-state, starts and the normal startup of generating integrated magneto (2); When delayer (A) time-delay finishes, its output (a
0) the output high potential, at this moment, if startup and generating integrated magneto (2) fail to start smoothly and generation stall, then its turn signal (v
i) be electronegative potential, the input (b of comparator (B)
2) also be electronegative potential, at this moment, the output (b of comparator (B)
0) be high potential, the control end (k of gate-controlled switch (1)
i) be high potential, gate-controlled switch (1) is opened, and starts power supply and is cut off, and starts and generating integrated magneto (2) thereby protected effectively.Gate-controlled switch (1) can be electronic switch or electronic electromagnetic unit switch.The purpose of delayer (A) is set, and is will give start and one of generating integrated magneto starts the accelerating time (being generally in three seconds), if compare at the very start, can form that mistake is protected and the normal startup that influences engine.
Owing to adopted time-delay relatively to judge the startup working condition of startup and generating integrated magneto, so this circuit is very effective.
The following describes accompanying drawing:
Fig. 1, Fig. 2 are the circuit theory diagrams of an embodiment of a kind of motor protective circuit of proposing of the present invention; Fig. 1 shows when starting and generating integrated magneto when normally starting; the operating state that gate-controlled switch (1) is closed; Fig. 2 shows when starting and generating integrated magneto can not normally start the time; operating state when gate-controlled switch (1) is opened (protection); the connection status and the course of work about Fig. 1, Fig. 2 formerly elaborate, and this is to repeat no more.
Claims (2)
1. motor protective circuit; one termination power positive pole of gate-controlled switch (1); another termination of gate-controlled switch (1) starts and an end of generating integrated magneto (2) and an end of delayer (A); start and the other end of generating integrated magneto (2) and another termination power cathode of delayer (A), it is characterized in that: the output (a of delayer (A)
0) meet the input (b of comparator (B)
1), the input (b of comparator (B)
2) connect and start and generating integrated magneto turn signal (v
i), the output (b of comparator (B)
0) meet the control end (k of gate-controlled switch (1)
i).
According to a kind of motor protective circuit described in the claim 1, it is characterized in that; Gate-controlled switch (1) is electronic switch or electronics, electromagnetism unit switch.
