600 HP

The Ward Leonard WL12BB060 The Ward Leonard WL12BB060 inverter-rated AC induction motor is the industry’s only 600 HP motor that fits into a standard 400 HP frame, delivering up to 50% more torque and horsepower—for top drives that want more power to drill deeper, longer and faster than ever before.

Key Advantages:

  • Industry’s coolest running form wound 600 HP motor
  • Up to 5 years / 10,000 hours of continuous duty
  • Weighs 33% less than the standard 600PH motors
  • Grinds through more difficult geologies
  • Overcomes friction in the hole wall at greater depths
  • Jogs the pipe faster and with more power
  • Makes longer horizontal runs
  • Threads larger diameter pipes
