Abstract: A hybrid electric weight device applying to exercise equipment, comprising: a frame body, a load mechanism having a main shaft, a motor torque member and a spring member, a force mechanism having at least a set of rods, load cells and handles, an acceleration processing board having an acceleration sensor and a microprocessor, a digital watch arranged on the frame body for users inputting an exercise set value; and a servo controller. When operating the force mechanism, the users feel the load generated by both motor torque member and spring member of the load mechanism; the servo controller continues to compare differences in the value of the load cell, digital watch and acceleration processing board and then corrects the current value to drive the motor torque member for the users feeling smooth while operating the force mechanism.
