Large machine shop drills
use induction motors.
Oilwell drilling machines
use diesel motors or
diesel-electric rigs.
Drilling rigs can be massive structures
housing equipment used to drill
water wells, oil wells, or natural
gas extraction wells,
or they can be small enough
to be moved manually
by one person and such
are called augers.
Radial drilling machine.
Upright drilling machine.
Automatic drilling machine.
Multiple Spindle drilling machine.
The electric motor drives the spindle
either directly with a gearbox or
with a series of belts and pulleys
. The electric motor can either be
mounted to the base of the
machine or at the top of the column.
Like the feed rate, the rotational
speed can be adjusted for different
drill bits and materials.
Designed for on and off shore
drill rig service,
bulk fuel terminals,
and transfer stations.
Designed to withstand
hazardous-duty applications
with demanding service factor
needs. Labyrinth style recess
shaft slinger increases bearing
life and multiplies durability.

usually by deceptive or
dishonest means. rig an

advance for a desired result.
Workover rigs are very similar to
drill rigs in that they are truck-
mounted mobile rigs that travel
between job sites on public roads.
However, these machines are
generally located at the job site
for weeks before relocating to
a different location.
Using the mud flow for the
drill turbine the brushless DC
motor power is then harnessed for
localised electronics in the drill head
avoiding the need for batteries.
