Magnetic resistor control assembly

A magnetic resistor control assembly for a body training machine, comprising:

• a main shaft installed to a base of a body training machine;
• a rotor having an inner hole, and a magnetic isolation ring being installed to a wall of the inner hole;
• one rear end of the rotor having a bottom;
• an axial hole being formed in the bottom of the rotor;
• and a bearing being fixed to the axial hole;
• a stator formed by an inner disk, and an outer disk;
• an outer diameter of the stator being slightly smaller than an inner diameter of the magnetic isolation ring;
• an adjusting unit;
• the inner disk and outer disk clamping an adjusting unit;
• two positioning holes being formed on the inner disk near an outer edge;
• the adjusting unit having magnetic guide iron sheets which are pivoted to the positioning holes of the inner disk by using positioning pins;
• the pivoting portions of the magnetic guide iron sheets being positioning ends;
• each of the magnetic guide iron sheet being installed with a permanent magnet;
• another end of each magnetic guide iron sheet having a swingable arm end;
• a distal end of each arm end being extended inwards with a fixing rod which extends inwards;
• a distal end of each fixing rod being installed with a roller;
• a sliding block set having guide tracks at a left and a right side thereof;
• an outer lateral wall of each guide track having a track trench;
• a lower middle portion of the sliding block set having a round hole;
• the roller being installed and rollable in the guide track;
• and the retaining rod of the roller being placed within the track trench;
• and
• a controller installed at an outer side of the stator;
• the controller having a transfer pin which displace in the straight grooves and a power wire for power transfer;
• when the transfer pin drives the sliding block set to move in the straight grooves, the gap between the permanent magnets and the magnetic isolation ring is changed.
