Abstract
There is provided a piling hammer comprising a linear electric machine comprising a mover connected to a ram block for striking a pile, a processor operatively connected to the linear electric machine and configured to determine a recoiled kinetic energy from striking the pile using a ram block connected to a mover of the linear electric machine, determining at least a portion of the determined recoiled kinetic energy for regenerative braking of the mover to a peak position, control the linear electric machine to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.

A piling hammer comprising:
- a linear electric machine comprising a mover connected to a ram block for striking a pile;
- a processor operatively connected to the linear electric machine and configured to:
- determine a recoiled kinetic energy from striking the pile using a ram block connected to a mover of the linear electric machine;
- determining at least a portion of the determined recoiled kinetic energy for regenerative braking of the mover to a peak position;
- control the linear electric machine to decelerate the mover to the peak position based on the portion of the determined recoiled kinetic energy.
A method for striking a pile by a piling hammer comprising:
- providing a processor operatively connected to a linear electric machine;
- determining a recoiled kinetic energy from striking the pile using a ram block connected to a mover of the linear electric machine;
- determining at least a portion of the determined recoiled kinetic energy for returning the mover to a peak position after striking the pile;
