Abstract
The utility model relates to a terminal box holder for an electromagnetic braking electric machine. The utility model is provided with a conducting wire inlet butted with a main body of an electric machine, and one side of the conducting wire inlet is provided with a mounting face of a rectifying device, wherein the mounting surface of a rectifying device is arranged at a place near a fan air outlet of the electric machine and the heat radiating device is arranged between the lower part of the mounting face of the rectifying device and the main body of the electric machine. The heat radiating device is composed of a plurality of heat radiating columns, so that heat radiating device has favorable heat radiating effect when flowing air passes by the heat radiating columns from any direction. The heat of the rectifying device is delivered downward into the heat radiating columns through the mounting face of the rectifying device of the terminal box holder, and heat on the heat radiating columns of the terminal box holder and the outer wall of the terminal box holder is emitted out to ambient air for cooling under the convective action of the flowing air and natural air at the fan air outlet of the electric machine, so that the normal work of the rectifying device is ensured.
Description
Technical field
The utility model relates to the junction box seat of a kind of motor, particularly a kind of electromagnetic braking motor.
Background technology
The brake apparatus of electromagnetic braking motor comprises electromagnet, tripping spring, armature and brake disc in the prior art, its electromagnet adopts the direct-flow magnet exciting coil excitation, so need to install rectifying device in the terminal box of motor, output DC stream inserts magnet exciting coil.Its weak point is: because the electronic component in the rectification circuit is subjected to the influence of operating temperature in input current heating and the motor, and heat distributes and does not go out, and the time has been grown and caused the circuit element mis-behave, damages rectifying device easily.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of electromagnetic braking motor junction box seat with great heat radiation effect.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of junction box seat of electromagnetic braking motor, it is provided with the wiring inlet that docks with the motor main body, be provided with the rectifying device installed surface in wiring inlet one side, be characterized in: the rectifying device installed surface is arranged near electric motor fan air outlet place, is provided with heat abstractor between rectifying device installed surface bottom and motor main body.
The technical problems to be solved in the utility model can also come to realize that further described heat abstractor is some thermal columns by the following technical programs.Owing to be thermal column, moving air all has great heat radiation effect through any direction of thermal column.The technical problems to be solved in the utility model can also come by the following technical programs further to realize that junction box seat adopts the whole manufacturing of aluminum material.Its good heat dissipation effect.
The utility model compared with prior art, it discloses a kind of junction box seat of novel electromagnetic braking motor, its rectifying device installed surface is arranged near electric motor fan air outlet place, is provided with some thermal columns in rectifying device installed surface bottom.The heat of rectifying device passes to heat abstractor downwards by the rectifying device installed surface of junction box seat, under the effect of electrical motor fan air outlet moving air and natural air convection current, the heat abstractor of junction box seat and the heat on the junction box seat outer wall be dispersed in the surrounding air cool off.Thereby guarantee the operate as normal of rectifying device.
