YZR and YZ series motors are suitable for driving various hoisting machinery and auxiliary equipment, with high overload capacity and mechanical strength, especially suitable for short-term or intermittent operation, frequent starting, braking and significant vibration and impact device of. The motor has good sealing performance. The protection level of the motor used in general places is IP44, and the protection level of the motor used in metallurgical places is IP54. The YZR series are wound rotor three-phase asynchronous motors, and the YZ series are squirrel-cage rotor three-phase asynchronous motors. . The insulation class of the motor is divided into F class and H class. Class F is suitable for general places where the temperature of the cooling medium does not exceed 40 °C; class H is suitable for metallurgical places where the temperature of the cooling medium does not exceed 60 °C, and the two motors have the same parameters. The metallurgical motor enclosure protection grade is IP54; the lifting motor enclosure grade is IP44 YZ series motors are suitable for driving various hoisting machinery and auxiliary equipment, with high overload capacity and mechanical strength, especially suitable for short-term or intermittent operation, frequent starting, braking and equipment with significant vibration and impact . Crane Duty Motors S4 duty motor Metallurgical Motor Protection class The metallurgical motor casing protection grade is IP54; The motor housing grade for lifting is IP44. cooling method Frame 112-132: IC0041 Frame 160-355: IC0141 Frame 400: IC0151 The main difference between YZR hoisting motor and YZ hoisting motor is: YZR series motors are wound rotor motors, and YZ series motors are squirrel-cage rotor motors. Crane Duty Motors S4 duty motor Metallurgical Motor From the model meaning of YZR motor and YZ motor, it can be known that Y represents asynchronous motor, Z represents lifting and metallurgy, and R represents that the rotor is wound type. The YZ motor has no R and is a squirrel-cage rotor motor. Insulation class In addition, both YZR and YZ hoisting motors are suitable for driving various types of hoisting machinery, metallurgical machinery and other similar equipment, and their power levels and installation dimensions are in line with IEC standards. Crane Duty Motors S4 duty motor Metallurgical Motor The insulation grade of the metallurgical motor is H, and the insulation grade of the lifting motor is F. Junction Box The motor stator junction box is located on top of the frame and can be wired from either side of the frame. transfer method The motor adopts coupling or gear transmission. When using spur gear transmission, the diameter of the pitch circle of the gear should not be less than 2 times the diameter of the shaft extension. Crane Duty Motors S4 duty motor Metallurgical Motor YZ hoisting motor working system The working system of this series of motors is divided into eight types: S2, S3, S4, S5, S6, S7, S8, S9, and the standard working system is S3 40% (that is, the working system is S3, and the load duration rate is 40%. The cycle is 10min). The following are the most commonly used working systems of this series of motors. Crane Duty Motors S4 duty motor Metallurgical Motor 1. Short-time work (S2) Running for a given time under constant load, the motor is not long enough to reach thermal stability, and then shuts down and de-energized for a time sufficient to re-cool the motor to within 2K of the temperature of the cooling medium (see Figure 1 ) 2. Intermittent cycle work system (S3) It operates on a series of identical duty cycles, each cycle including a period of constant load operation and a period of shutdown and de-energization (see Figure 2). In this working system, the starting current of each cycle will not have a significant effect on the temperature rise. 3. Intermittent cycle duty including starting (S4) A series of identical duty cycles are run, each cycle including a start-up period that has a significant effect on temperature rise, a constant-load operation period, and a shutdown and de-energization period (see Figure 3). 4. Intermittent cycle duty including electric braking (S5) Crane Duty Motors S4 duty motor Metallurgical Motor Operates in a series of identical duty cycles, each cycle including a start-up time, a constant load operation time, an electric braking time and a shutdown and de-energization time Golden Triangle YZ series hoisting and metallurgical three-phase asynchronous motors, referred to as YZ hoisting motors or YZ hoisting and metallurgical motors, are wound rotor type three-phase asynchronous motors, which are widely used in various types of hoisting machinery, metallurgical auxiliary The electric drive of equipment and other similar equipment has high overload capacity and mechanical strength, especially suitable for short-term or intermittent periodic work, frequent starting, braking and equipment with significant vibration and impact. One of our company's dock crane motor YZR180L-8 could not be arranged due to equipment modification. After consulting the dock crane manufacturer, we decided to change this motor to YZ180L-8. Crane Duty Motors S4 duty motor Metallurgical Motor Have the following questions to ask: 1. Can the rotor lead wire of the YZR180L-8 motor be short-circuited for use, and how long-term short-circuit use will affect the motor. (You can save the cost of repurchasing the YZ180L-8 motor) 2. What are the similarities and differences between YZR180L-8 motor and YZ180L-8 motor? How is the design and production process different? 3. What is the difference between the use conditions of the YZR180L-8 motor and the YZ180L-8 motor, and are there any problems that should be paid special attention to? Both are asynchronous motors for lifting metallurgy, but the YZR lifting motor is wound. It can be started frequently, with large overload capacity and high slip rate. The conditions of use are the same. YZR180L should be started by series frequency sensitive resistor. It can be used for short-circuiting the rotor lead wire. Long-term short-circuit use has no effect on the motor. Crane Duty Motors S4 duty motor Metallurgical Motor YZ type motor is an asynchronous motor for lifting metallurgy, generally a squirrel cage motor. The YZR180L-8 power 11kW motor rotor lead wire is short-circuited to run, and the operation mode is directly started. Can. The cable should preferably be more than 10 square meters. The motor has good sealing performance. The protection level of the motor used in general places is IP44, and the protection level of the motor used in metallurgical places is IP54. The YZR series are wound rotor three-phase asynchronous motors, and the YZ series are squirrel-cage rotor three-phase asynchronous motors. . The insulation class of the motor is divided into F class and H class. Class F is suitable for general places where the temperature of the cooling medium does not exceed 40 °C; class H is suitable for metallurgical places where the temperature of the cooling medium does not exceed 60 °C, and the two motors have the same parameters.
