Abstract
A single-phase capacitive operation micro-motor with a large starting torque belongs to a novel motor which has the same windings L1, L2 and capacitor C with JX, DO, DO2 series motors and also has a starting large capacitor C1, a control switch K and a corresponding pulling mechanism. The starting large capacitor C<1> is connected in series with the switch K then connected in parallel with the capacitor C to increase a starting torque at starting. The switch K is cut off by pulling machinery linkage or by hand when the motor running at full speed. The starting large capacitor C<1> can be connected in parallel with the capacitor C or a capacity of the capacitor C is increased during a short time operating. JX, DO, DO2 series motors can have a starting performance of JY series motors in the utility model.
Description
The utility model relates to a kind of electrical micro-machine, is the improvement to JX, D0, D02 series capacitor-operated motor.
Along with electronic product to produce and the people's lives every field progressively deeply, market is to also harshness more of the requirement of motor performance, cost, especially the demand to single-phase electrical micro-machine is more and more wider.A kind of big starting torque, cheap single-phase electrical micro-machine are the products of current urgent need, as the electric hoisting clothes-horse in the balcony, " patent " be following kind surplus in the of ten, comes out and there is a kind of product, does not have big starting torque, cheap single-phase electrical micro-machine is its one of the main reasons.
According to prior art " D02 series single-phase capacitor running electrical micro-machine; higher power factor and efficient are arranged, and volume is little, and is in light weight; but starting torque less (0.35-0.6 times of nominal torque) is only applicable to the machinery of electric fan, ventilation blower and various zero load or light start ".(draw from " newly organized practical eelctrical engineering handbook ", weapon industry publishing house, version in 1998, the 231st page), and the good B02 of starting performance, C02, the YL serial motors, because of all in machine, establishing centrifugal switch, thereby volume is big, the cost height, and there is not the following product of 60W (as can be known according to " eelctrical engineering handbook " 5.16 pages " selecting the micro asynchronous motor parameter list for use " of Shanghai science tech publishing house, B02 series is 60-370W, and C02 series is 120-750W, and YL series is 250W-3000W) according to above-mentioned situation as can be known: the single-phase electrical micro-machine that does not at all have the big starting torque of 60W following (not containing 60W) now on the market.
The utility model purpose is: with simple method, cheap cost, improve JX, D0, D02 serial motors, make its starting performance near YL series, and keep the advantage that its volume is little, in light weight, cost is low, to satisfy the demand in market.
Technical characterictic of the present utility model is: under the main winding L1 that does not change JX, D0, D02 serial motors M, auxiliary winding L2 data conditions, with big capacitor C
1In parallel with C, to increase former capacitor C value, improve starting torque with this.
When being used for the place of short-run, extremely short as the duration of runs, C
1Directly in parallel with C, or directly increase the C value, do not establish switch.
When being used to drag the load of continuous running, the starting capacitance C that is increased
1After travel switch XK connects, or C shown in pressing in the empty square frame of Fig. 2
1After a manual switch S K connects, in parallel with C again.XK or SK closure during starting, C
1In parallel with C, motor has big starting torque.After motor M 2 startings, during near full speed,, disconnect travel switch XK by the interlock of institute's driving machinery; Or manually disconnect SK, make C
1Disconnect.
If with the commentaries on classics stopping time of electromagnetic switch control motor M 3, with capacitor C
1After one group of normally opened contact K2 of starting button connects, in parallel with C again.During starting, press starting button QA, make capacitor C
1In parallel with C, motor M 3 has big starting torque starting operation.When the approaching full speed of M3, decontrol button QA again, make K2 disconnect C
1Cut from the circuit in parallel with C, motor M 3 runs well.
After adopting said method to improve, the utility model can make the starting torque of JX, D0, D02 serial motors bring up to about in the of 1.5 times of nominal torque, and does not reduce other performances of original motor, thereby has enlarged the scope of application of JX, D0, D02 serial motors.
Accompanying drawing 1 is the circuit diagram that the utility model increases JX, D0,1D02 serial motors starting torque.
Accompanying drawing 2, accompanying drawing 3 are that the utility model is in order to drag full load starting, two kinds of circuit of continuous running machinery.
The utility model is described in further detail below in conjunction with accompanying drawing.
In accompanying drawing 1, M1 is JX, D0, D02 serial motors, and L1 is the main winding of motor, and L2 is the auxiliary winding of motor, and C is the capacitor in order to starting and running.Auxiliary winding L2 connect with capacitor C back and L1 and connecing.The effect of C is that electric current differs 90 ° of phase angles among electric current and the L1 that guarantees among the L2 in the circuit, produces rotating magnetic field electric motor starting is turned round.During starting, the size of starting torque is relevant with the size of C value within the specific limits.The corresponding increase of the big starting torque of C value.In original motor, unlikely too high because the series circuit of C and L2 is attempted by participation operation on the power supply with L1 all the time when motor rotation for guaranteeing electric machine temperature rise, thereby the C value can not be too big, the main cause that this is JX, D0, D02 serial motors starting torque is little.The utility model is formerly not consider under the situation of electric machine temperature rise, with big capacitor C
1Capacity in parallel with C, as to increase C or directly replace former electric capacity with big electric capacity can make the starting torque increase of JX, D0, D02 serial motors.This also is practicable under extremely short situation of operating time.As in order to dragging the electric lifting clothes hanger, every liter or fall once, required time less than ten seconds, the motor stall of promptly cutting off the power supply, electric machine temperature rise can not transfinite, the circuit working of complete available accompanying drawing 1 (also available big electric capacity is replaced C).
Accompanying drawing 2 is circuit diagrams that the utility model is used to drag full load starting, the continuous machinery that turns round, and being applicable to circuit breaker control motor changes the place of stopping.L1, L2, C, C among the figure
1Identical with the effect among Fig. 1.Difference is C
1In parallel with C again after travel switch XK or hand switch SK (as shown in phantom in Figure 2) series connection.During starting, earlier with C
1In parallel with C good through switch XK or SK, the closing of power circuit breaker power supply that closes then, motor have big starting torque starting operation, when the approaching full speed of motor speed, disconnect XK or the moving SK of disconnection of armrest by dragging mechanical linkage, make C
1From with the C parallel circuits excise, motor runs well, thus it is too high and damage to have guaranteed that motor is unlikely to temperature rise.
Accompanying drawing 3 is circuit diagrams that the utility model is used to drag full load starting, the continuous machinery that turns round, and is applicable to the place with the stall of electromagnetic switch control motor.L1, L2, C, C among the figure
1Identical with the effect among Fig. 2, J is an electromagnetic switch, and J1, J2, J3 are its normally opened contact, and TA is a stop button, and QA is a starting button, and K1, K2 are QA two pairs of normally opened contacts independently separately.Start big capacitor C
1In parallel with C through K2, J is connected on the power supply through the alternate path of QA, K1 and J3.During starting, press QA, K1, K2 closure, C
1In parallel with C through K2, J obtains electricity through QA, K2, J1, J2, J3 closure, and motor M obtains electric starting operation.J is through the J3 self-insurance.When the approaching full speed of motor speed, unclamp QA, K2 and disconnect C
1From with the C parallel circuits excise, motor runs well.
