AC frequency control electric motor as power source, low speed high
torque flexible drive, constant power output, energy-efficient,
without noises and pollution.
Frequency control electric drive system consists of AC power
source, AC frequency converter and AC electric motor. Power sources
have three input powers: 75kW (40ton), 55kW (30ton), 37kW (20ton),
they adapt to different oilfield transformer. Hook block speed is
auto-adjusted according to different load, control system takes
closed-loop design, and it can control electric motor’s rotating
speed and torque exactly, low speed, good performance, output
constant torque in the extreme low speed. Transducer can protect
the electric motor in the condition of overloading, overheating and
overcurrent. When there is no rotating speed, electric motor in the
braking mode, it can keep the maximum torque, static hook load.
Transducer makes the most of electric motor’s power, it has short
period overloading capacity (1.5-2times); it can be started
frequently or started steadily with negative load.
Max. Load: 151875lbf (675kN)
Derrick height: 59ft (18m)
Hook blocks hoisting speed: 3.9ft/s (1.2m/s)
