YZR Series 45kw Squirrel Cage 3 Phase Ac Induction Motor Two Phase Induction Motor 4 Pole Induction MotorYZR and YZ series winding rotor and squirrel cage rotor three-phase asynchronous hoist motors are for hoisting and metallurgical machines and other similar equipments. 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 Germanystandard 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 etallurgical 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. http://www.hongdajidian.vip.seo...-phase-ac-induction.html
