Preferably, in addition to respectively it is connected on the electric current pole changer at rotor coil TQ both ends in rotor power consumption loop
Q1。
Compared with prior art, the present invention has technique effect beneficial below：
Braking circuit of the present invention, by the stator coil being serially connected originally and turned by moment for being powered off in motor
Subcoil is disconnected by the normally opened contact of contactor, while stator coil power-off time hysteresis rotor is broken by time-delay relay
Electric certain time, still there is certain magnetic field on this period stator, and moment after a loss of power is existed by rotor loop of consuming energy
An energy consumption resistor is accessed in rotor coil, the rotor after power-off still in rotation produces potential under the influence of a magnetic field, in rotor
Electric current is produced in the power consumption loop that coil and energy consumption resistor are formed, the kinetic energy that rotor rotates is converted into heat energy, disappeared by energy
Consumption makes motor stop the rotation rapidly.Braking circuit of the present invention is not involved in work in motor normal work, but breaks in motor
