✔Voltage: 110V; Power: 6W; Speed: 12rpm(50HZ)/15rpm(60HZ); Gear Reduction Ratio: 2GN90K; Approximate Dimensions((L*W*H)): 6.13*2.41*2.41 inches; Max Rated Torque: 28.3lb.in(50HZ)/23lb.in(60HZ);

✔Controller safety range: If the motor load is small and not operated for a long time, the speed controller can be adjusted to 35% of the full speed. When the motor load and work continuously for a long time. the controller shouldn't be lower than 60% of the full speed;

✔Why the speed of motor can only be adjusted to a certain range: because the motor is slowed down by reducing volt, after volt is reduced, the torque will also become smaller, and it may overload; at this time, due to the increase of current, the heat dissipation will become worse, and motor will heat up seriously, which is easy to cause the insulation failure of the stator coil and the machine short circuit;
