YR Series wound-rotor three-phase asynchronous motor (IP44) is a chief derived series motor from Y series motor (IP44).  Better starting performance and requirement of the speed adjustment for the motor can be gained by adjusting the external resistance of rotor.

Many parts of series YR (IP44) are the same as that of series Y (IP44).  For corresponding to frame size, they have identical mounting dimensions and tolerances, but the overall dimension of series YR is longer than that of series Y.  The carbon brush collector ring device of motor is placed at the outside of  end cover.

Series YR provide the same insulation class and the degree of protection by enclosure as series Y, so do the cooling form.  The connection of stator  winding is "Y", so is that of rotor winding.

This series motor is suitable for starting heavy loads.
