YZR lifting motor is suitable for driving all kinds of lifting equipment and metallurgical auxiliary equipment, with high overload capacity and impact toughness, especially suitable for short-term or intermittent operation, frequent start, brake and obvious vibration and impact equipment.
The motor has good airtightness, and the protection grade of the motor for general places is IP44, and the protection grade of the motor for metallurgical places is IP54. YZR is wound rotor three-phase asynchronous motor.
The insulation class of the motor is divided into F class and H class. Class F is applicable to general sites with cooling medium temperature not exceeding 40℃; Class H is suitable for metallurgical places where the cooling medium temperature does not exceed 60 ° C, and the two motors have the same parameters.
Protection grade
The protection grade of motor casing for metallurgy is IP54; Hoist heavy motor casing class IP44
Insulation class
The insulation class of metallurgical motor is H, and that of lifting motor is F.
Junction box
The motor stator terminal box is located at the top of the frame and can be wired from either side of the frame.
Transmission mode
The motor shall be driven by coupling or gear. When spur gear is used, the pitch circle diameter of gear shall not be less than 2 times of shaft extension diameter.
