Claim Text:
1. A system for stimulating healing of tissue at a wound site comprising: a porous pad configured to be positioned at a wound site and adapted to be covered by a drape to form a seal for providing negative pressure to the wound site; a pumping mechanism fluidly coupled to the porous pad for applying negative pressure to the wound site, the pumping mechanism including a pump and an electric motor for driving the pump to generate an actual pressure; and a power management motor control that compares the actual pressure to a target pressure and determines a tentative motor drive power for reaching the target pressure, and then either (i) applies the tentative motor drive power to the electric motor when the tentative motor drive power is greater than or equal to the stall power of the electric motor or (ii) prevents the tentative motor drive power from being applied to the electric motor if the tentative motor drive power is less than the stall power of electric motor.
