- devilage In case of failure of the power supply of the system, this potential energy is likely to drive the system suddenly in the opposite direction, it is called devilage, and can cause runaway with a speed of deviation reaching values that can be dangerous for people and equipment.
- Such pumps store in operation a potential energy in two forms, namely on the one hand a torsion energy in the drive rod of the pump which is twisted on itself and on the other hand a hydrostatic energy corresponding to the column of fluid in the well.
- a braking device is provided in order to avoid that in the event of engine stopping, the accumulated potential energy suddenly drives the system in the opposite direction.
- This device comprises for example a mechanical disk or centrifugal brake or a hydraulic braking device.

- a switching system allowing: in a first configuration, that the electric machine operates as a motor in the case where the coupled device is normally driven or generator in the case where the coupled device is normally driving, and in a second configuration, that the electric machine operates as an autonomous generator, the electrical energy generated by the electric machine being dissipated in the machine and in a dissipative load.
- the dissipative load that is connected to the machine can provide more or less of the dissipation of energy when the machine operates as a stand-alone generator.
- a significant part of the dissipation of the energy can take place in the machine itself, in particular in the stator windings, in particular in the case where the dissipative load has no significant impedance and its impedance is substantially less than the internal impedance of the machine.
- the term "dissipative load" should not be understood in a limiting sense and the power dissipated in this load can be much lower than that dissipated in the machine.
- the power dissipated in this load can be much lower than that dissipated in the machine.
- the invention makes it possible to create a braking torque with the electric machine.
