What are the advantages of a YZR motor? What's the difference with the YZ motor?
YZR series motors are suitable for driving various hoisting machinery and metallurgical auxiliary equipment, with high overload capacity and mechanical strength, especially suitable for short-term or intermittent operation, frequent starting, braking and equipment with large vibration and impact. The motor has good sealing performance. The protection level of motors generally used is IP 44, and the protection level of motors used in metallurgical places is IP54. YZR series three-phase asynchronous motor with wound rotor.
Advantages of YZR motor:
YZR motors can be divided into F grade and H grade in terms of insulation grade. F grade is suitable for general occasions where the cooling medium temperature does not exceed 40℃, and H grade is suitable for metallurgical places where the cooling medium temperature does not exceed 60℃.
1. In terms of protection level: the protection level of the metallurgical motor enclosure is IP 54, and the starting and reuse motor enclosure level is IP 44.
2. In terms of cooling method: base 112-132 IC0041 base 160-355IC0141 base 400IC0151
3. In terms of insulation grade: the insulation grade of metallurgical motors is H grade, and the insulation grade of starting and recycling motors is F grade.
4. Junction box connection: The motor stator junction box is located on the top of the valve seat and can be connected through any side of the seat.
5. In terms of transmission mode: the motor adopts coupling or gear transmission. When using spur gear transmission, the diameter of the gear meshing circle should not be less than 2 times the shaft extension diameter.
In order to further understand the YZR motor, you can compare the difference between the YZ and YZR series motors
Both YZ and YZR series motors are suitable for driving all kinds of hoisting metallurgical machinery and other similar equipment. They have the characteristics of large overload capacity and high mechanical strength. shock equipment.
The power class and installation dimensions of the motor comply with the International Electrotechnical Commission (IEC) standard, and its corresponding relationship is the same as the DIN 42681 and JEM 1202 standards. 40 ℃ general place, H class is suitable for metallurgical places where the ambient temperature does not exceed 60 ℃, these two motors have the same parameters. The motor protection grade used in general places is IP 44, and the motor protection grade used in metallurgical places is IP 54. YZ series motors are squirrel-cage rotor motors, and YZR series motors are winding rotor motors.
The above is a detailed description of the advantages of the YZR motor. By comparing the difference between the YZ and YZR series motors, you can better understand the characteristics and advantages of the YZR motor.
