Detailed Product Description

 

YZR Series 3-Phase Wound-Rotor Asynchronous Motor for Metallurgy and Crane Applications is the latest design and features with the large overload capacity and high mechanical strength.

 While YZRE Series 3-Phase Wound-Rotor Asynchronous Motor with Brake for Metallurgy and Crane Applications is the YZR series motor toped up with an AC brake. The AC brake is powered directly from a three phase power supply without rectified diodes. The AC brakes are not only quick response braking (100 times quicker than a DC single phase brake) but also have improved reliability and long service life. The advantages of AC brakes also include precise positioning, such as no axial movements, and the capability of a wide adjustable range of braking torque, such as from zero (0) to any desired values. The AC brake is an approved patent from the National Patent Bureau. The approval patent number is: 97206492.3.

 

YZR and YZRE series motors are especially suitable for driving various types of metallurgical machines and cranes and / or other similar equipments. These series motors are light weight and easy to install.

 The motor has been also awarded an approved patent from the National Patent Bureau with number of ZL 200820057339.5.

 Above series motors are available in the direct connection between the motor and the gearbox. Please refer to tables below for details.

 These series motors can be customized designed and produced to meet your request.

 

 

Application

 

The ranges of applications

This series of motors are specially designed for service on cranes and hoists. They can also be used for similar applications such as material handling, weirs and sluices, and lifts of all types. These motors can serve as auxiliary motors in rolling mills or wherever intermittent drives are required.

 

 

Design features:

l,Degree of protection
The clegree of protection of enclosure of metallurgical motors is IP54 and that of crane motors is IP44.
2,Cooling method
Frame 112-132    IC410

Frame 160-400    IC411

3, Construction and mounting arrangemens are shown in table 5.

4,Insulation class
The insulation of metallurgical motors is of H class and that of crans motors is F class.

5,Terminal box
The terminal box for the stator is fitted on the top of the frame and connection can be made on either side ,of the framse.

6,Type of drive
Motors are designed for coupling or spursear drive when gear drive is used, the pitch diameter of the pinion should not be less than twice of that of the shaft extension.

7, Brush holder and brush
The brush molders of the YZR series motors are provided with spring of constant pressure of the latest design so that the pressure between the collector ring and brush can remain unchanged while the brush are worn out during operaton. The type of brushes used is J201 and size sare shown in table 6.
