YGP Three Phase AC Induction Electric Frequency Changeable Variable Speed Roller Table and Steel Plant Motors
---------------------------------------------------------------------------------------------
Applications
Widely used for the metallurgy equipment, especially the ones which are controlled by variable frequency system. The motor suits not only for live roll table of S1 duty mode but also for the work roll table of periodic operation, frequent start and stop, positive and reversal rotation.
General Description
- Frame sizes: 112-400
- Rated output: 1.1-250Kw
- Voltage: 380V
- Frequency range: 5- 100Hz
- Duty Cycle: S5
- FC: 60%
- Degree of protection: IP54 / IP55
- Insulation class: F, H
- Poles : 4,6,8
Features
Good overload capacity and mechanic strength, wide range of speed regulation, smooth operation.
Technical Characteristics
This series motor is of F or H insulation grade, IP54 protection (motor of IP55,IP56 can also be customized), IC410 cooling method.
Wide frequency range 5~100Hz, of which 5~50Hz is for maintaining constant torque and 50~100Hz is for constant output.
With good overload capability the motor can work with overload of 3.5~4.0 times of rated torque (general purpose motor can bear about 2 times).
This series motors have good performance at low speed. The starting torque at 5Hz is 1.3~1.8 times of its rated value.
