Description

2000 kW Slip Ring Motor – High Voltage Heavy Duty Industrial Motor

A 2000 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 large-scale heavy-load scenarios, this 2000kW model balances power output, energy efficiency, and grid compatibility for core heavy industrial sites with high power demand.

Our Three Phase Slip Ring Motor covers complete medium and high voltage specifications, including 3300V Slip Ring Motor, 6000V Slip Ring Motor, 6600V Slip Ring Motor, 10000V Slip Ring Motor and 11000V Slip Ring Motor, fully compatible with global industrial power grid standards. Available as both a Medium Voltage Slip Ring Motor and High Voltage Slip Ring Motor, it supports customized voltage configuration based on on-site grid conditions. 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 2000kW wound rotor motor perfectly adaptable to ultra-high-inertia equipment startup demands without causing grid fluctuation or power system impact.

Compared with conventional squirrel cage motors, the AC Slip Ring Motor offers superior starting performance for high-inertia and large-load 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 under full-load working conditions. The 2000kW power rating fills the performance gap between medium-large power and large-power industrial motors, serving as a cost-effective alternative to oversized 2500kW/3000kW motors for precisely matched heavy-load conditions, avoiding redundant power loss and excessive procurement costs.
