Electromagnetic plungers (EP)

Looking for information on availability or creation of an EP capable of replicating the force of a 10kg spring 150mm long. Needs to achieve a reciprocal rate (RR)of 25 cycles per second.
Preferably with suitable control gear both the RR and force would be variable. Would prefer the EP to be double acting without the need for a spring although a return spring would suffice.
Run off DC LiPo power supply.
Duty cycle of 30-70%
Typical requirement would be 70% 1-5 cycles and 30% 20-30 cycles in random order.
What would be the approximate physical size and power consumption of such a unit?

Hey Sam!

Wow, that’s way over my head! Maybe someone else on here knows about EP’s though!
