Description
Technical field
The utility model belongs to electrical technology field.
Background technology
Electric drill or electric planer are after energized starts running, and rotor drives drill point or rotor high speed rotating.After cutting off the electricity supply, drill point or rotor can not stop immediately, easily cause the staff personal injury, and object damages.
Summary of the invention
The utility model provides a kind of unidirectional series excitation formula motor emergency braking apparatus, and to solve present electric drill or electric planer after cutting off the electricity supply, drill point or rotor can not stop immediately, easily cause the staff personal injury, the problem that object damages.The technical scheme that the utility model is taked is: comprise unidirectional series excitation formula motor, 1 of ganged switch and 3 connections, 7 points of 3 connecting coil I, 8 of coil I connect ganged switch 6 points, 6 and 4 connections, 4 14 points that connect stator coil IV, 15 of coil IV connect power supply, ganged switch 1 point, 59 points that connect inductance II, 10 end carbon brush that switch through sub-commutator III of inductance II, the other end carbon brush of this rotor commutator connects 11 points of inductance V, 12 o'clock of inductance V links to each other with 13 o'clock, 14 of stator coil IV.
During work, 1 of ganged switch and 3 connections, 3 connecting coil 7 points, 8 connect 6 points, 6 and 4 connections.During power connection, one-way motors starts rotation, when dump owing to adopt ganged switch and inductance 1,2 coil circuits to connect, because rotor commutator two ends 10 points, 11 have equiphase, the polarity of stator 1 and stator 2 the two poles of the earth windings is opposite, rotor stands between two magnetic poles as the suction of iron nail after having a power failure, immediately braking.
Advantage of the present utility model is: novel structure, and easy to use.When cutting off high speed rotating electric drill power supply, rotor can be braked immediately, has solved present electric drill or electric planer after cutting off the electricity supply, and drill point or rotor can not stop immediately, easily cause the staff personal injury, the problem that object damages.
