YH series motors are derived from Y series motors. The motor is characterized by such outstanding feature as higher locked rotor torque, samller locked rotor current higher slipping and soft mechanical charactor. They are suitable for driving machines with larger inertia torque and impact load such as shearers, presses and small hoisters and so on.
Rated output, outline dimension and construction of YH motors is the same with that of basic Y series. Duty type is intermittent(S3), The cyclic duration factor can be either 15%, 25%, 40% or 60%.
Rated voltage of YH series motors is 380V, rated frequency is 50Hz, insulation class is B and protection degree is IP44.
