Technical Field

The present invention relates to an electromechanical drive system for driving a device requiring mechanical energy in the form of torque for its operation.

Background

Various drive systems are known from the prior art. Typically, these systems include a main drive and a transmission for transferring the electrical power generated by the main drive to the equipment that requires work for its operation.

Patent EP 0083369 Bl discloses a system powered by a battery. Battery depletion is a serious limitation for loads that require a large amount of power for their operation. The basic task of the invention is to provide a system that will use a small high speed motor to generate power for heavily loaded loads while minimizing battery drain. The invention solves the task by means of a feedback loop of the generator and a voltage controller which are constantly connected in a circuit, so that no switching takes place between the drive mode and the charging mode. The system is a combination of a mechanical device that increases the number of rotational speeds and a mechanical device that decreases the number of rotational speeds through a hydraulic transmission device through which an increase in electric power is achieved, and the hydraulic transmission device includes a hydraulic pump and a hydraulic motor. The hydraulic transmission is controllable to control the output speed of its mechanical output based on the speed of the mechanical input. The coupling and drive mechanism provides power distribution to the load and the generator that charges the battery via the voltage controller. The battery is regenerated. The authors of the present invention have also noted that the life of the battery is extended at the same time.

The disadvantage of this solution is the large number of various components, resulting in a more expensive system; furthermore, these components take up a lot of space.

Technical problem

The technical problem is how to conceive an electromechanical drive system which will have a simple structure and will adapt its power to the current needs of the load, while it will charge the power source if the need for power of the motor decreases. Another technical problem solved by the present invention is how to provide an electromechanical drive system that does not occupy a large amount of space and has a compact structure.

Solution to the technical problem

The technical problem is solved by an electromechanical drive system for mechanical force loading, comprising:

at least one electric motor connectable to a power source and provided with a shaft,

a first switch for switching on/off the electromechanical drive system,

at least one first transmission connected on one side to a first end of the shaft of the electric motor and connectable on the other end to a load,

-at least one generator, and

at least one second transmission connected on one side to a second end of the shaft of the electric motor, which second end extends in a direction opposite to the direction of the first end of the shaft of the electric motor, and on the other side to the generator,

wherein the generator is electrically connectable with the power source and the electric motor via the second switch such that current from the generator can be directed to the electric motor and/or the power source.

Once the electromechanical drive system is turned on via the first on/off switch, the motor receives power from the power source. The electric motor converts the electric power in the form of torque via the first transmission into mechanical force that can be easily used for the load for its operation. At the same time, the electric motor provides mechanical energy to the generator, which generates electricity, through the second end of the shaft and the second transmission. Such electric power is supplied to the motor as needed, thereby increasing the electric power of the motor, resulting in an increase in mechanical force. The power generated in the generator may be supplied to the power source via the second switch if no higher mechanical force is required.

An electric motor with two-ended shafts makes it possible to drive the mechanical energy load and the generator simultaneously. Thus, the generator can supply additional power to the motor or simultaneously charge the power source. An advantage of the electromechanical drive system of the present invention is that it provides a simple system with a small number of components and which can adapt to the energy requirements of the load.

Detailed Description

The present invention is described in more detail below.

The technical problem is solved by an electromechanical drive system 1, 1a for a mechanical force load 2, the electromechanical drive system 1 comprising:

at least one electric motor 3 connectable to a power source 4 and provided with a shaft,

a first switch 5 for switching on/off the electromechanical drive system 1, 1a,

at least one first transmission 6 connected on one side to a first end 7 of the shaft of the electric motor and connectable on the other end to the load 2,

at least one generator 8, 8a, and

at least one second transmission 9 connected on one side to a second end 10 of the shaft of the electric motor, which extends in a direction opposite to that of the first end of the shaft of the electric motor 3, and on the other side to the generator 8, 8a,

wherein the generator 8, 8a is electrically connectable with the power source 4 and the electric motor 3 via the second switch 11, such that current from the generator 8, 8a can be directed to the electric motor 3 and/or the power source 4.

Once the electromechanical drive system 1, 1a is switched on by the first on/off switch 5, the electric motor 3 receives power from the power source 4. The electric motor 3 converts the electric power in the form of torque via the first transmission 6 into mechanical force that can be easily used for the load 2 for its operation. At the same time, the electric motor 3 provides mechanical energy to the generator 8, 8a generating electric power through the second end 10 of the shaft and the second transmission 9. Such electric power is supplied to the electric motor 3 as needed, thereby increasing the electric power of the electric motor, resulting in an increase in mechanical force. The power generated in the generator may also be supplied to the power source 4 via the second switch 11 if no higher mechanical force is needed.

The electrical conductors between the generator 8 and the motor 3 and between the motor 3 and the power source 4 may each be provided with a semiconductor diode 16.

The power source 4 may be a power supply network, a battery, a rechargeable battery pack, or the like.

The motor 3 and the generators 8, 8a may be arbitrarily selected, and may be: AC or DC, single or multi-phase, synchronous or asynchronous, brushed or brushless motor/generators, with permanent magnets or electromagnets, with water or air cooling, etc.

The electromechanical drive system 1, 1a may comprise a control system and/or other elements and devices such as inverters, frequency converters, etc. that meet the individual operational and output needs defined by the user.

The first transmission 6 and the second transmission 9 are selected on the basis of the load requirements from the following: rigid drive systems, belt drives, gear drives, clutches, mechanical switches, chain drives, pneumatic drives, hydraulic drives, magnetic drives, and the like.

Another embodiment of the electromechanical drive system 1a makes the system more compact. In this embodiment, the housing of the electric motor is circumferentially coated with an electromagnetic insulating layer 12 that prevents mutual electromagnetic influence between the electric motor 3 and the generator 8 a. The rotor 13 of the generator is formed as a socket which is able to receive the second transmission and at least a part of the electric motor, preferably the main part of the electric motor. Within the rotor 13 of the generator, magnets 14, which may be permanent magnets or electromagnets, are circumferentially arranged. The electromagnet may be a short circuit cage. On the part of the electric motor 3 not beyond the rotor of the generator, the stator 15 of the generator is arranged circumferentially and rigidly connected thereto. The circumferential part of the stator 15 of the generator extends circumferentially around part of the rotor 13 of the generator with magnets, accommodating the coils for inducing current and other elements required for power generation and transmission to the motor or power supply.

The electromechanical drive system 1a may comprise a cooling device for cooling the electromechanical drive system.
