High Voltage Wound Rotor Motor for Heavy Industrial Applications
3000kW Slip Ring Motor
A 3000kW Slip Ring Motor, also known as a Slip Ring Induction Motor, Wound Rotor Motor, or Wound Rotor Induction Motor, is a high-performance electric motor specifically designed for heavy-duty industrial applications requiring high starting torque and reliable continuous operation.
As a Wound Rotor Slip Ring Motor, the rotor windings are connected to external resistors through slip rings and carbon brushes. This design enables smooth starting, reduced inrush current, and excellent torque performance, making it ideal for driving high-inertia equipment.
Our Three Phase Slip Ring Motor series is available in both High Voltage Slip Ring Motor and Medium Voltage Slip Ring Motor configurations to meet various industrial power requirements.
Working Principle
Unlike squirrel cage motors, a Slip Ring Induction Motor features a wound rotor whose windings are connected to slip rings mounted on the shaft.
During startup:
External resistors are connected to the rotor circuit.
Starting current is significantly reduced.
Starting torque is greatly increased.
Mechanical stress on the driven equipment is minimized.
As the motor accelerates, the external resistance is gradually removed until the rotor is short-circuited for normal operation.
This operating principle makes the Wound Rotor Motor an ideal solution for applications requiring high starting torque.
Key Features
High Starting Torque
The Heavy Duty Slip Ring Motor can provide starting torque up to 200–250% of rated torque, making it suitable for heavy-load startup.
Reduced Starting Current
Compared with conventional squirrel cage motors, the AC Slip Ring Motor significantly reduces starting current, minimizing voltage drops and protecting the electrical network.
Excellent Reliability
Designed with premium insulation systems, precision bearings, and optimized cooling structures, our High Voltage Slip Ring Motor ensures stable operation under demanding industrial environments.
Easy Maintenance
The slip ring and brush assembly is designed for convenient inspection and maintenance, reducing downtime and maintenance costs.
High Efficiency
Advanced electromagnetic design delivers excellent efficiency, low vibration, and long service life.
