In modern steel plants and metallurgical production lines, ordinary industrial motors simply cannot withstand the extreme operating conditions found in roller table systems. High ambient temperatures, heavy shock loads, frequent acceleration and deceleration, conductive dust, and continuous variable speed operation all place enormous stress on the drive system.
The YGP Series Metallurgical Motor from LUAN JIANGHUAI MOTOR CO., LTD. is specifically engineered for these demanding environments. Designed for inverter-driven roller table applications, the YGP series delivers stable low-speed torque, reliable high-speed operation, and exceptional durability under continuous heavy-duty conditions.
With optimized electromagnetic design, reinforced mechanical structure, and advanced insulation technology, the YGP series has become a trusted solution for steel mills, rolling plants, and automated conveying systems worldwide.
The YGP series is a variable frequency asynchronous motor specially developed for metallurgical roller table systems.
The motor is optimized for:
Continuous casting lines
Hot rolling production lines
Cold rolling systems
Billet conveying equipment
Shearing and finishing lines
High-temperature conveying systems
Unlike standard industrial motors, the YGP series is designed to maintain stable performance during:
Frequent starting and stopping
Heavy impact loading
Low-speed high-torque operation
Wide-range frequency adjustment
Continuous inverter operation
Modern metallurgical production requires precise synchronization and flexible speed control throughout the entire process.
The YGP series supports:
Constant torque operation at low frequency
Constant power operation at high frequency
Stable operation across a wide speed range
Typical operating range:
5Hz – 50Hz: Constant torque control
50Hz – 100Hz: Constant power control
Through optimized stator and rotor design, the motor maintains stable magnetic performance even at very low frequencies, reducing overheating risks and improving conveying precision.
This makes the YGP series especially suitable for synchronized roller table systems requiring accurate speed coordination.
Metallurgical roller tables are exposed to severe mechanical impact during operation. Hot steel billets, sudden load changes, and material accumulation can create extreme shock loads.
To ensure reliable operation under these conditions, the YGP series adopts:
Reinforced motor frame structure
High-strength end covers
Optimized shaft design
Heavy-duty bearing configuration
The motor can typically achieve peak torque greater than three times rated torque, allowing it to withstand sudden overload conditions without production interruption.
Unlike ordinary motors, the YGP series is specifically designed for inverter power supply systems.
Frequency converters generate high-frequency voltage pulses that place significant electrical stress on motor windings. To improve long-term reliability, LUAN JIANGHUAI MOTOR CO., LTD. uses:
Special inverter-duty magnet wire
Advanced vacuum pressure impregnation (VPI)
Enhanced insulation systems
Harmonic-resistant winding design
Standard insulation classes include:
Class F insulation
Class H insulation
These designs effectively reduce the impact of harmonic heating, insulation aging, and corona discharge caused by inverter operation.
Steel mill environments contain high levels of conductive dust, oxide scale, moisture, and heat radiation.
To improve operational reliability, the YGP series commonly adopts:
IC410 self-cooling structure
IC411 forced cooling structure
The fanless self-cooling design reduces dust accumulation inside the motor and eliminates risks associated with damaged cooling fans or blocked air passages.
The motor housing is specially designed with optimized cooling ribs for efficient heat dissipation under continuous operation.
The YGP series incorporates multiple protection measures to ensure long service life in harsh industrial environments.
Features include:
Multi-layer shaft sealing system
High-temperature resistant grease
Dust-proof bearing protection
Moisture-resistant internal structure
Reinforced terminal box design
The heavy-duty terminal box provides excellent vibration resistance and sealing performance, ensuring stable electrical connection even in severe operating environments.
