The invention relates to devices capable of maintaining a given current value of consumers when powered from a constant voltage source. The device can be used to control the current in the windings of the suspension electromagnets and the direction of vehicles.

The aim of the invention is to reduce mass and energy losses and increase reliability.

The drawing shows a diagram of a device for controlling electromagnetic mechanisms. ,

The device contains the first 1 second 2 key elements that can be made on the basis of transistors, pulse thyristor voltage regulators, etc., the first 3 and second 4 diodes, the first power source 5, the electromagnet 6, the second power source 7, the second electromagnet 8. Power supplies 5 and 7 must have two-way conductivity. They can be made in the form of batteries or rectifiers with capacitors.

The first key element 1 is connected between the plus of the power source 5 and the clip of the electromagnet 6, the second clip of which is connected to the minus of the power source 5. The second key element 2 is connected between the minus of the second power source 7 and the clip of the second electromagnet 8, the second clip of which is associated with the common point of the power sources 5 and 7. The first diode 3 is connected by anode with the minus of the second power source 7, and the cathode is connected to the common point of the first key element 1 and 1 of the electromagnet 6. The second diode 4 is connected to the plus side of the power source 5, and the anode is connected to the common point of the second key element 2 and the second electromagnet 8.

The device works as follows.

When unlocking the first key element 1, a current flows along the circuit of the power supply source 5 - the first key element 1 - electromagnet 6 - power source 5. The current in the electromagnet increases.

When locking the first key. element 1, the current of the electromagnet 6 flows along the contour of the second power source 7 - the first diode 3 - the electromagnet

kit 6. The current in the electromagnet 6 decreases.

For uniform consumption of energy from power supply 5 and power supply 7, a second electromagnet 8 is used. When unlocking the second Key element 2, a current circuit plus a second power supply 7 is formed — a second electromagnet 8 — the second key element 2 — minus the second power source 7. The current of the electromagnet increases. When the second key element 2 is locked, the current of the electromagnet flows along the contour of the second electromagnet 8 — the second diode 4 — the power source 5 — the second electromagnet 8.

By changing the duration of the on state of the key elements 1 and 2, it is possible to regulate the currents in the electromagnets independently of each other.

The energy consumption associated with the operation of the thyristor-Sh) 1X switch devices (it is 30-50% of the total energy consumption) decreases 1.5-2 times, which reduces the weight of batteries, which are used as emergency power supply,

Reducing the number of elements with the same load on them improves the reliability of the device.

Thus, the technical and economic advantages of the proposed device are a reduction in mass and losses, as well as an increase in reliability.
