A coil outgoing line wiring board is additionally arranged at the end surfaces of the frame plates outside the stator body; a printed circuit for connection is arranged on the wiring board; and the coil outgoing line heads are electrically connected with the printed circuit on the wiring board. The wiring board is arranged on the end surface of the stator body by fixed points caused by welding of a plurality of small plastic columns arranged at the edges of the frame plates as well as soldering of the coil outgoing line heads. The two ends of the printed circuit of the wiring board are respectively and electrically connected with an input power line and a control signal wire. And bucket-shaped grooves for insertion of hall sensors are arranged at the inner sides of the frame plates and moldings of the hall sensors are electrically connected with the wiring board. According to the utility model, the advantages of the brushless electric machine are as follows: the coil outgoing lines are respectively and regularly connected to the wiring board, so that the appearance of the stator body is clean, the end cover can be disassembled conveniently and the insulation performance of the stator is stable; line-in and line-out processes are clear; the bucket-shaped grooves for insertion of the hall sensors at the inner sides of the frame plates enable the hall sensing devices to be secure and reliable.
Description
Technical field
The utility model relates to motor and makes the field, refers to that specifically a kind of stator body end face sets up the brushless electric machine of terminal block.
Background technology
Brushless electric machine so a commutation control cabinet is all arranged usually, relies on the commutation signal of electronic control system output to realize the moment commutation owing to do not have carbon brush and commutation sheet.But the multiply lead-out wire of stator exciting coil also must be intertwined by several the end of a thread, divides A, B, C three-phase to insert the plug that is connected with control cabinet respectively then.So in the lead-out wires of coil junction; Reliable in order to insulate; To coat Huang Laguan, twine insulating tape etc. toward contact, not only be prone to hinder the assembling of electric motor end cap, but also can reduce the insulation property of motor; Even end cap takes place when assembling, bump broken insulating barrier and the phenomenon that is short-circuited, existence influences the hidden danger of motor safety.
The utility model content
The purpose of the utility model is: in order to overcome the potential safety hazard that there is the motor stator insulated performance of influence in existing product; Set up a lead-out wires of coil terminal block to brushless motor stator; Make things convenient for closing smoothly of electric motor end cap during assembling, stablize the insulation property of motor, eliminate safe hidden trouble.
The technical scheme of the utility model technical solution problem is: the stator body end face is set up the brushless electric machine of terminal block; Except that p-m rotor; Also comprise stator body and skeleton dish, set up a terminal block on the skeleton dish end face of said stator body outside, said terminal block is provided with the printed circuit that connects usefulness; Printed circuit is electrically connected by certain rule on the end of a thread of stator coil lead-out wire and the terminal block; The electric contact of terminal block two ends printed circuit is electrically connected with input power cord and control signal wire respectively, thereby forms brushless electric machine commutation control system.
Also be provided with some coil the end of a thread welding holes and skeleton dish plastics pillar installing hole on the said terminal block, fixing after said terminal block welds with the welding of plastics pillar and coil the end of a thread a little is arranged on the end face of skeleton dish.
Said skeleton dish inboard also is provided with the bucket shape groove of assigning Hall element, and the stitch of said Hall element is electrically connected with the printed circuit of terminal block, makes the hall sensing device safe and reliable.
The benefit of the utility model is: be connected to lead-out wires of coil on the terminal block regularly; Make end cap easy to assembly, guarantee that stator insulation is stable and reliable for performance, the stator body outward appearance is clean and tidy; Circuit is imported, output is clear understands that the installation of hall sensing device is more safe and reliable.
