Abstract
The utility model provides a sensing mechanism of a motor governor which overcomes the short service life of the governor because of direct contact and friction and comprises a sensing coil and an inductor. The purpose of controlling the rotary speed and braking of the motor is realized through changing the relative positions of the inductor and the sensing coil and the different control signals converted by a conversion and control system. The utility model is particularly applicable to the governors of motors and electric sewing machines which need speed governing frequently. The utility model has wide application range.
Description
(1) technical field
The utility model relates to a kind of machine governor, relates in particular to a kind of sensor-based system part of machine governor.
(2) background technology
The electric machine speed regulation that generally uses has mechanical speed governors and electronic speed regulation two big classes at present, and the sensor-based system of mechanical governor mainly adopts clutch, utilizes the mutual friction between driving-disc and the grinding disk to adjust rotating speed; The sensor-based system of electron speed regulator mainly adopts potentiometer, and directly the regulator potentiometer contact position is adjusted variable-resistance size, reaches the purpose of adjusting motor speed.Owing to need frequent contact and directly friction between the sensor-based system inner part of these two kinds of speed regulators, easily make sensing element produce wearing and tearing and scratch, cause speed regulator to lose efficacy, speed governing effect instability, speed regulator is short useful life.
(3) summary of the invention
The utility model provides a kind of sensing mechanism of machine governor, by changing the relative position between induction coil and the inductor, produce different inductance, convert different control signals to, reach control motor speed, braking and switching purposes by switching control system.
For achieving the above object, the technical scheme that adopts is: the utility model is made up of induction coil and inductor, induction coil is a solenoid coil that is formed by insulated conductor densely packed coil skeleton, inductor is the magnetic conduction object, do not contact between inductor and the induction coil, their relative position can be handled variation.Because inductor is different with the relative position between the induction coil, can produce different inductance in the induction coil, variation inductance outputs to switching control system by the lead of drawing on the induction coil, converts different control signals to by switching control system, realizes the adjustable continuously of motor speed.
Because the utility model is eliminated directly contact and mechanical wear, make machine governor realize stepless speed control, the speed governing effect stability, realized the stepless nothing wearing and tearing speed governing of motor, long service life, be particularly suitable for needing the speed regulator of the equipment such as motor, electric sewing machine of frequent speed governing to use, have broad application prospects.
(4) description of drawings
Fig. 1 is the perspective view of an embodiment of the utility model.
(5) embodiment
Fig. 1 is embodiment of the utility model, it is to be made of induction coil 2 and inductor 1, induction coil 2 be one by the close solenoid coil that forms on the bobbin 4 of insulated conductor 3, inductor 1 is the iron staff of an external diameter less than coil rack 4 internal diameters, one end of inductive rod 1 is through in the coil rack 4 of induction coil 2 hollowly, the other end links to each other with operating control mechanism, operating control mechanism firmly, pulling inductive rod 1, inductive rod 1 produces relative displacement in induction coil 2, the physical length that inductive rod 1 is in the induction coil 2 changes, the inductance of induction coil 2 changes, output to switching control system by the lead 5 of drawing on the induction coil 2, convert different control signals to, the control motor speed by switching control system, braking and switch.
Claims (2)
1, a kind of sensing mechanism of machine governor, it is characterized in that: it is made up of induction coil and inductor, induction coil is a solenoid coil that is formed by insulated conductor densely packed coil skeleton, inductor is the magnetic conduction object, do not contact between inductor and the induction coil, relative position between them can be handled variation, because inductor is different with the relative position between the induction coil, can produce different inductance in the induction coil, output to switching control system by the lead of drawing on the induction coil.
