Abstract
The utility model relates to a positive and negative rotating controller for asynchronous motors, which is composed of two groups of control circuits which are composed of a delay relay, a travel switch, and an AC contactor. The utility model can realize the regular positive and negative rotating of the asynchronous motor, and the structure is simple.
Description
The utility model relates to a kind of single-phase asynchronous motor positive and negative rotating controller.
In fish production, there is a kind of short spacing to prolong fishing and angles rope winding machine, its guiding take off angle mechanism need by screw rod clocklike clockwise or rotate counterclockwise and realize its left and right moving, and screw rod clockwise or rotate counterclockwise generally by motor clocklike positive and negative and transfer realization.General now by manually controlling the rotating of motor, operate very inconvenient.
The purpose of this utility model is at the problem of above-mentioned existence and a kind of asynchronous motor positive and negative rotating controller is provided.
The utility model is achieved in that it is made up of the control circuit of two groups of parallel connections, every group of control circuit is made up of 1 A.C. contactor, 1 time-delay relay and 1 travel switch, and its line connecting relation is to seal in time-delay relay and be connected with the normally closed point of travel switch in the coil of A.C. contactor.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a line map of the present utility model.
In this embodiment, this controller is respectively by two time-delay relay J
S1, J
S2, two travel switch K
1, K
2, two A.C. contactor J
D1, J
D2Form J wherein
S1, K
1And J
D1Form a control circuit, time-delay relay J
S1Seal in A.C. contactor J
D1Coil Q
2In and with travel switch K
1Normally closed point connect.Similarly, J
S2, K
2, J
D2Form another control circuit, two control circuit power supplys that insert in parallel.
During work, A.C. contactor J
D2Normally closed point connect time-delay relay J
S1Coil Q
1Control time-delay relay J
S1Coil Q
1Energising, time-delay relay J
S1Normal battle closed, the normal battle is series at A.C. contactor J
D1Coil Q
2With travel switch K
1Normally closed, time-delay relay J
S1After delaying time some seconds, A.C. contactor J
D1Closure is supplied with motor and is just being changeed electricity, and motor just changes.Travel switch J
S1Normally closed point is opened, A.C. contactor J
D1Coil Q
2Outage, A.C. contactor J
D1Normally closed closed, and connect time-delay relay J
S2Coil Q
3Energising.After delaying time some seconds, time-delay relay J
S2Normal battle closed, and be connected to A.C. contactor J
D2Coil Q
4With travel switch K
2Normally closed, A.C. contactor J
D2The motor reverse current is supplied with in action, the motor counter-rotating.So repeatedly, just can realize motor forward and backward clocklike.
