Description

Motor stator, motor and electric tool
Technical field
This utility model belongs to machine field, in particulars relate to a kind of motor stator, a kind of motor including described stator, and a kind of electric tool using described motor.
Background technology
The structure of the motor of prior art is made up of stator and rotor two parts.When motor runs, stator and rotor interact and produce electromagnetic torque and induction electromotive force.Stator generally comprises stator core and stator winding, and stator winding is fixed on stator core.The stator winding of general electric tool series excited machine has two actuating coils, and stator core has two magnetic poles, and one actuating coil of coiling on each magnetic pole has four actuating coil the end of a thread, and this stator is referred to as non-brake stator.Non-brake stator winding needs the armature winding with rotor to be connected to constitute motor circuit by elements such as switch, carbon brush and commutators, and this motor is referred to as non-brake motor.
Magnetic field is produced after the energising of non-brake stator actuating coil, under the interaction of rotor and stator, motor rotation output torque and power, make electric tool work.Brake motor is a kind of motor based on non-brake motor, its stator winding has four coils, two of which is actuating coil, two is restraining coil (also referred to as brake coil), general work coil-conductor is compared with thick and the number of turn is less, and restraining coil conductor is compared with thin and the number of turn is more, rotating around an actuating coil and a restraining coil on each stator core magnetic pole, can first coiling brake coil also be then further around actuating coil processed on same magnetic pole of the stator in a pair stator slot, can also first coiling actuating coil also be then further around brake coil processed on same magnetic pole of the stator in a pair groove.By actuating coil and the restraining coil of stator winding, armature winding and commutator, the element such as carbon brush and switch is according to suitable circuit composition brake motor system.With the electric tool such as electric circular saw of brake motor system when operator presses and holds and presses switch, when being in mode of operation, actuating coil energising provides excitation, and rotor produces electromagnetic torque and makes motor rotation, output torque and power, makes electric tool work.The electric tool of strap brake electric system such as electric circular saw is when operator's release-push, by switch, circuit is switched, make stator brake coil and armature winding, switch contact, the molecular brake circuit of rectification works, it is in braking mode, rotor is made to produce electromagnetic system power owing to rotor inertia is rotated in armature conductor in the electromotor electromotive force and brake circuit produced the self-excitation electric current produced, rotor is made to stop operating rapidly, make to include rotor, the kinetic energy of the drive system of travelling gear and saw blade etc. changes into the thermal energy consumption of stator and rotor coil, so that motor obtains fast braking, the safety of raising instrument or raising work efficiency.Therefore, a total of eight coil the end of a thread of stator winding of the brake stator of such brake motor are to be connected.When connecting, operator need to differentiate these the end of a thread.Multiple the end of a thread connect the difficulty adding motor assembling so that operator is easy to make mistakes on connecting.And this mistake often is difficult to be noticeable during the end of a thread of stator coil connects, until motor is fully assembled when but can not running or run abnormal and is just found.
Connection between the end of a thread of brake stator winding typically can use binding-type, i.e. the end of a thread is first by equipment crimp type terminal, actuating coil and the restraining coil of brake stator are connected by the requirement of composition brake circuit, on connection terminal, overlap insulated sleeve again, finally need on the position of fixing the end of a thread at such as stator coil end etc. with insulating tape or rope colligation.The connected mode of this colligation need to use manual work so that manufacturing cost is the highest, connects and easily makes mistakes, nor is suitable to substitute with machine carry out automated production.
Having a kind of method saving the end of a thread quantity is that braked by stator two coils of winding (and/or stator Working winding) are formed by an enamel-covered wire coiling, i.e. first one coil of coiling on a magnetic pole, the most same enamel-covered wire does not cut off continuous across another coil of coiling in stator yoke to another magnetic pole, but the benefit of such coiling is to reduce the terminal connected in the middle of, but coiling man-hour can be increased.
