The biggest advantage of three-phase asynchronous YRKK series copper rotor motor is that the starting current can be controlled within a certain range, and the starting torque will not decrease with the decrease of current like ordinary cage rotor motors. Therefore, it not only ensures the starting torque but also reduces the starting current without using large capacity equipment (including transformers, switches, and wires). So it is very suitable for users who require high starting torque and limited power capacity.
