YZR Three Phase Electric motor for crane hoist and machinery
YZ, YZR series is the up to date design electric motor with the characteristic of big overload capacity and high mechanical strength, which is specially adequate for driving all sorts of metallurgical machinery and hoisting machine or the other similar equipment. YZR series is wound rotor electrical motor and YZ series is cage type electrical motor.
YZR series motors are widely used for driving lifting and metallurgical machines and other similarequipment. YZR series motors are of wound rotors type, while YZ series motors are of squirrel cage type. YZR and YZ series winding rotor and squirrel cage rotor three-phase asynchronous hoist motors are for hoisting and metallurgical machines and other similar equipment. With great load capacity and mechanical strength, they are suitable for equipment with short time or intermittent duty, frequency start or brake, obvious shock and impact.
The standard range of power output and mounting dimensions are in comply with the recommended standard of IEC 72. The relation between range of power output and mounting dimensions are similar to Japanese standard JEMI202 and Germany standard DIN42681, so that most of them can be interchanged.
The motors posses a better enclosure, degree of protection IP44 for normal site condition and IP54 from metallurgic condition. There are two classes of F and H insulation,Class F is applicalbe to suit temperature which cool air does not exceed 40 under normal condition,Class H is suitable for metallurgical sites when ambient temperature no exceeding 60 both motors have same data.
