Abstract
The utility model provides a zero interference micro motor which is characterized in that shunt resistors are arranged between a commutator and a winding coil of the micro motor, so that the shunt resistors are connected with the winding coil in parallel. The shunt resistors are common resistors or SMD (Surface Mount Device) resistors, and the resistance of each shunt resistor is less than 1k ohms. The three shunt resistors are welded on pins of three wiring pins of the commutator respectively. The zero interference micro motor has the beneficial effects that the design of an IC (integrated circuit) is simplified, and the IC cost is reduced; and only resistance elements are adopted, therefore, the cost is low, and the structure is simple.
Description
Technical field
The utility model relates to a kind of micromachine, more particularly relates to one. plant the zero interference micromachine that the control IC circuit working is not produced electromagnetic interference.
Background technology
Continuous development, renewal along with electronic toy, electric device, micromachine is used more and more wider as the dynamic power machine that converts electric energy to mechanical energy, and in the design of some electronic toys and electric device, all adopted the IC circuit that is used to control machine operation, but when present known micromachine is worked, winding coil can produce a high-frequency pulse current when commutator commutates, this electric current can produce a kind of electromagnetic field by another winding coil, and the IC circuit is produced electromagnetic interference.Be one group of jamproof circuit of design in the IC circuit to this way to solve the problem at present, the cost of IC circuit is improved, volume increases.
The utility model content
To have micromachine now in the defective aspect the interference in order overcoming, thereby to provide a kind of zero to disturb micromachine, this electrical micro-machine can not produce the electromagnetic field that the IC circuit working is disturbed in the running.
The purpose of this utility model is achieved in that a kind of zero disturbs micromachine, it is characterized in that: between the commutator of described electrical micro-machine and the winding coil shunt resistance is set, makes shunt resistance and winding coil parallel connection.
Described shunt resistance is conventional, electric-resistance or Chip-R, and its resistance is less than 1K ohm.
Described shunt resistance is 3, is welded in respectively on three wiring pin pin of commutator.
The beneficial effects of the utility model are to have reached simplification IC circuit design, reduce the IC circuit cost, and micromachine have only adopted resistive element, and cost is low, and is simple in structure.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the utility model structure longitudinal section.
Embodiment
As shown in Figure 2: in shell 10, be provided with magnetic shoe 9, driving shafts 5 in the magnetic shoe 9 are bearing in the bearing 7 in the end cap 8 that is pressed into shell 10, rotor core 4 on the driving shaft 5 is wound with three auxiliary winding coils 3, three lead-out wires of winding coil 3 are connected with three wiring pins of commutator 1, three shunt resistances 2 of on three wiring pins of commutator 1, burn-oning, make shunt resistance 2 and winding coil 3 parallel connections, external power is given winding coil 3 energisings of commutator 1 by the spring brush on the end cap 86, and under the action of a magnetic field of magnetic shoe 9, make rotor core 4 drive driving shaft 5 rotation and output torques, finish the transfer process that electric energy converts mechanical energy to.
As shown in Figure 1, winding coil 3 and shunt resistance 2 parallel connections connect wherein two wiring pins of commutator 1 again.According to the inductance value of winding coil, generally below 1K ohm, when motor commutation was worked, shunt resistance just in time ran out of the high-frequency electrical pulses flow that winding coil 3 produces the resistance of shunt resistance.Therefore the high-frequency pulse current of motor generation can not produce the IC Control current and disturb.Have simple in structurely, production cost is low, is fit to advantages such as extensively popularization.
