The 1500 kW high-voltage slip ring motor (wound rotor induction motor) is a premium heavy-duty drive tailored for challenging industrial loads. Its core advantage lies in the unique wound rotor design, which allows external resistance access via slip rings to deliver ultra-high starting torque (250% rated torque) and extremely low inrush current — a key superiority over standard squirrel cage motors. Engineered for 6kV/10kV/11kV high/medium voltage systems, this three-phase motor enables soft startup for high-inertia equipment. It drastically reduces grid impact and mechanical impact on driven equipment, effectively solving common industrial pain points such as voltage drop and equipment startup damage. As an optimized medium-large power model, it avoids energy waste of overrated motors with perfect power matching. Core Advantages & Features - Superior startup performance: High torque with low starting current to stabilize power grid - Industrial durability: Rugged structure adapting to dusty, humid and vibrating harsh environments - Low total cost: Easily accessible slip ring and brush components for simple, low-cost maintenance - Full customization: Adjustable speed, IC611/IC81W cooling modes and mounting configurations Key Specifications 1500kW rated power, 50/60Hz frequency, 740–1500rpm speed; IP54/IP55 protection, Class F/H high-temperature resistant insulation. Applications Ideal for mining, cement and steel industries, perfectly driving ball mills, crushers, mine hoists, belt conveyors, large fans and rotary kilns. Compliant with IEC standards, this energy-efficient motor delivers stable long-term operation, helping global users boost productivity and cut operational & maintenance costs.
A 1500 kW Slip Ring Motor, also known as a Slip Ring Induction Motor, Wound Rotor Motor, Wound Rotor Induction Motor, or Wound Rotor Slip Ring Motor, is specifically designed for heavy industrial applications that require high starting torque, low starting current, and reliable long-term operation. Optimized for medium-to-large heavy-load scenarios, this 1500kW model balances power output, energy efficiency, and grid compatibility for mainstream heavy industrial sites.
Our Three Phase Slip Ring Motor is available as both a High Voltage Slip Ring Motor and a Medium Voltage Slip Ring Motor, with standard voltage ratings of 6kV, 10kV, and 11kV. The wound rotor construction allows external resistors to be connected through slip rings during startup, providing smooth acceleration while minimizing electrical and mechanical stress. This structural advantage makes the 1500kW wound rotor motor perfectly adaptable to high-inertia equipment startup demands without causing grid fluctuation.
Compared with conventional squirrel cage motors, the AC Slip Ring Motor offers superior starting performance for high-inertia equipment. It effectively reduces inrush current, improves power system stability, and delivers starting torque up to 250% of rated torque, making it ideal for continuous heavy-duty operation. The 1500kW power rating fills the performance gap between medium-power and large-power industrial motors, serving as a cost-effective alternative to oversized 3000kW motors for matched load conditions.
Our Heavy Duty Slip Ring Motor is widely used in industries requiring reliable medium-to-heavy load starting, where the 1500kW power rating is the most matched solution for process equipment:
