General Introduction

The KQR series liquid resistance starter is an advanced motor starting control device designed to improve the starting performance of large and medium-sized wound rotor motors.
By connecting a liquid resistor to the rotor winding, the starter provides automatic, stepless starting, dynamically adjusting the starting current over a scheduled time to ensure smooth motor acceleration under optimized current conditions.

This system effectively protects the motor, connected equipment, and the power supply network.
Compared to traditional starters, the KQR series offers significant advantages, including:

• Higher automation
• Lower starting current
• Energy savings
• Reduced mechanical and electrical impact

It is especially suited for heavy-duty and overload starting applications. Furthermore, the KQR starter enables smooth starts even under reduced power line voltages, lowering transformer capacity requirements.
Ideal for starting equipment such as ball mills, crushers, elevators, compressors, fans, and pumps.

Performance and Features

• Superior performance compared to other starter types
• Low starting current, typically less than 1.3 times the rated current
• Capable of continuous starts, 5 to 10 cycles
• Smooth starting, minimizing mechanical stress and torque impact
• Effective protection for motors and driven equipment
• Low voltage starting capability:
  • 6 kV motors can start smoothly at 5.5 kV
  • 380 V motors can start at 340 V
• Simple and reliable construction for robust industrial use
• Fully automatic operation, easy to install and maintain
