Technical parameters
DC motor
DC motors are high-power, high-torque drive motors for the DC electric drilling rig, used on drawworks, mud pumps, and rotary tables. Two types are named: series excited and separately excited.
- Compact size
- High speed
- High starting torque
- Direct voltage regulation and speed control
- Good braking feedback
- Wide applicable voltage range
