Drawworks

Assembly

AC-motor-driven winch spooling the drill line; multiple motors through a common gear train give several thousand kilowatts of hoisting power with regenerative braking. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Drawworks parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Stator Assembly 3 parts 4× AC hoist motor stators
2 Rotor Assembly 4 parts 4× Rotating member of an electric motor: a laminated steel core carrying permanent magnets or conductor bars, pressed onto a shaft that delivers the torque.
3 Helical Gear Pair 6× Reduction gear train
4 Encoder 4× Drum and motor position feedback
5 Drawworks Drum 1× Wire-line spooling drum
6 Disc Brake Unit 3× Hydraulic disc brakes
7 Clutch Unit 2× Drum engagement clutches
8 Ball Bearing 16× Deep-groove radial ball bearing.
9 Oil Seal 8× Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
10 Hydraulic Cylinder 4 parts 4× Brake and clutch actuation
11 Control & I/O Board 4 parts 2× Drive and brake control
