Motor-driven anti-resistance training device and stall control method thereof

The invention relates to the technical field of fitness equipment, and particularly discloses a motor-driven anti-resistance trainer and a stall control method thereof.The motor-driven anti-resistance trainer comprises a control module, a resistance pull rope, a permanent magnet generator, a brake motor, a speed sensor, a tension sensor and two brake relays; the control module comprises a built-in embedded single-chip microcomputer, and the built-in embedded single-chip microcomputer is internally provided with a muscle strength test and evaluation software module and an old people muscle strength level evaluation software module; when the speed of the permanent magnet generator is out of control, the resistance braking circuit is connected with the permanent magnet generator to realize resistance braking; and when the resistance pull rope is abnormally broken, the brake part is driven by the brake motor in an abnormal state to brake the resistance pull rope. Safety accidents caused by stall control caused by
