Abstract:
1. A strength training control device using a motor assembled S-type load cell, comprising: a) a base frame; b) a torque source, fixed onto the base frame, and comprising a motor and a gear reduction box, wherein the motor is a brushless motor or a DC motor, and an end of the gear reduction box is coupled to the motor, and another end of the gear reduction box includes a main shaft; c) an operating rod, with the bottom pivotally coupled to the base frame; d) a link mechanism, having an output end coupled to the main shaft of the gear reduction box and an input end coupled to the operating rod, and the link mechanism having: e) an electronic meter, fixed onto the base frame, and provided for a user to set a required torque value; and f) a servo controller, for comparing the difference between a sensed value of the S-type load cell and the set value of the electronic meter and after the difference value is adjusted, an electric current is output to drive the motor; whereby, after the motor torque is increased by the gear reduction box and then transmitted through the gearbox arm, the first link rod, the S-type load cell, the second link rod and the operating rod arm to the operating rod, the user obtains a torque value equal to the set value of the electronic meter.
