Description
Technical field
The present invention relates to electrical equipment manufacturing technology field；A kind of short circuit control for brake for motor braking fills
Put.
Background technology
Motor is indispensable parts in commercial production, and a lot of equipment will lean on driven by motor could run, very
Many occasions need motor to brake rapidly, and present motor braking method is a lot, and such as electromagnetic brake is exactly a kind of conventional motor
Braking method, and some are started, brakes frequently for motor, braking can make mechanical braking shortened equipment life frequently,
So that the production cost of enterprise increases.
Summary of the invention
It is an object of the invention to provide a kind of short circuit brake control, it can solve frequently to brake and make mechanical braking set
The standby lost of life, the problem that entreprise cost is high.
In order to solve the problems referred to above, the technical solution used in the present invention is: this short circuit brake control, including controlling
Case, is provided with chopper, fuse, the first catalyst, the second catalyst and thermorelay, described control in the case of described control chamber
Stop button and start button are installed on the chamber door of case processed；Described fuse, stop button, start button, the first catalyst
Forming the first contactor control circuit with thermorelay series connection, described first catalyst forms first with start button parallel connection and contacts
Device holding circuit, described fuse, stop button, start button, the second catalyst form second with thermorelay series connection and contact
Device control circuit, is serially connected with rectification diode, described rectification diode and described second in motor threephase stator winding respectively
Catalyst is in parallel.
Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that due to this
Bright is to be serially connected with rectification diode in motor stator winding, and its braking is circuit rather than machine, so frequently braking not
The lost of life of braking circuit can be caused.
Accompanying drawing explanation
Fig. 1 is the control chamber front view of the present invention.
Fig. 2 is the principle schematic of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Short circuit brake control shown in Fig. 1, including control chamber, be provided with in the case of control chamber circuit breaker Q F, fuse FU,
First catalyst KM1, the second catalyst KM2 and thermorelay FR, the chamber door of control chamber is provided with stop button SB1 and startup
Button SB2；Fuse FU, stop button SB1, start button SB2, the first catalyst KM1 and thermorelay FR series connection formation the
One contactor control circuit, the first catalyst KM1 is in parallel with start button SB2 forms the first catalyst holding circuit, fuse
FU, stop button SB1, start button SB2, the second catalyst KM2 and thermorelay FR series connection form the second catalyst and control electricity
Road, is serially connected with rectification diode V, rectification diode V and the second catalyst KM2 in parallel in motor threephase stator winding respectively.
When wanting motor properly functioning, circuit breaker Q F of closing, press start button SB2, the first contactor control circuit and
Second contactor control circuit simultaneously electric, the main contact of the second catalyst KM2 in parallel with rectification diode V is by rectification two grades
Pipe V short circuit, motor runs under the control of the first catalyst KM1；When needs motor is out of service, press stop button SB1,
First contactor control circuit and the second contactor control circuit dead electricity, second catalyst in parallel with rectification diode V simultaneously
The main contact of KM2 disconnects, and rectification diode V seals in the stator winding work of motor, and rotor has remanent magnetism, and at effect of inertia
Lower continuation rotates, and rotor remanent magnetic field cutting stator winding produces the faradic current of orientation；Stator-induced electromagnetic stream and rotor
Rotating excitation field interact, produce braking moment force motor stalling.
The present invention is without special control equipment, and during braking, stator-induced electromagnetic flow ratio empty load of motor starting current is little.
