YR series motors provide outstanding starting performance, delivering high starting torque with relatively low starting current, and allow speed regulation within a certain range.
They are especially suitable for:
- Power supply networks with insufficient capacity to start squirrel-cage motors
- Applications requiring long or frequent starting cycles
- Industrial processes requiring limited-range speed control
Wide Application Scope
YR series motors are widely used in heavy-duty equipment, including:
- Heavy hoisting equipment, rolling mills, wire drawing machines
- Mining crushers, compressor systems, large-capacity pumps
- Other heavy machinery requiring high starting torque and adjustable speed capability
Standard Technical Parameters
- Mounting arrangement: IMB3
- Duty type: Continuous duty (S1)
- Rated frequency: 50 Hz
- Rated voltage: 6 kV, 10 kV (other voltage levels available on request)
- Insulation class: F class
- Bearing system:
- IP54 bearing structure
- H355–630: grease-lubricated rolling bearings
- H710–1000: sleeve bearings with forced thin-oil lubrication
Core Technical Advantages – Assurance of Superior Quality
Innovative Rotor Design
The wound rotor structure provides superior starting performance compared with squirrel-cage motors.
By connecting external resistors or frequency-sensitive rheostats to the rotor circuit, smooth starting and effective speed regulation can be achieved, significantly reducing grid impact.
Optimized Cooling System
Multiple cooling options (IC01, IC11, IC21, IC31) allow users to select the most suitable solution based on operating conditions.
Optimized heat dissipation ensures stable operating temperatures under continuous heavy-load conditions, extending motor service life.
Estructura mecánica robusta
The frame and end covers are manufactured from high-strength materials and optimized through precise structural calculations and testing.
This design ensures excellent mechanical strength and dynamic stability, enabling operation under heavy load impacts and harsh environments.
Reliable Insulation System
Stator windings use F-class or higher insulation materials with anti-corona treatment.
The insulation system is processed using Vacuum Pressure Impregnation (VPI) technology, providing excellent moisture resistance and corrosion protection for reliable operation in high-temperature and high-humidity environments.
