New Technology Armak Air Motors replacing conventional Radial Piston Motors
Radial Piston Air Motors for many years were the dominating
type in high performance air motors.
They are a proven design, which has been supplied more or
less unchanged for more than 25 years.
The drawings show the big difference in the two designs:
on top is the new Armak Motor AGP; below is the equivalent
Radial Piston Motor - the more compact AGP motor is shown
inside this motor in grey colour.
A disadvantage of the Radial Piston Motors is the oil sump
as well as the breather opening which might allow water to
enter the motor oil sump. Mounting the motor onto a standard
IEC gear box requires an expensive adapter.
Some requirements of the machinery directive cannot be
fulfilled. And ATEX IM2 for mining is not available.
New Technology Armak Geared Piston Motors, also called rotating lobe motors
are designed to replace the Radial Piston due to their engineering advantages.
Armak Air Motors are available either with IEC flange or in a version directly
interchangeable to Globe Motors RM110 to RM510 with flange and shaft
identical to the RM-motors, but frequently with higher power. More than 900
Armak Geared Piston Motors are in use world wide.
End users do appreciate theses features:
totally closed motor housing. No entrance of water in wet surroundings, no oil sump.
vibration free running even at high motor rpm - can be compared to a turbine drive
non contacting torque producing parts, hence long operating life
a motor efficiency which gets better in operation
compact design with freedom of installation
smooth running from 75 rpm upwards
ATEX I M2 can be supplied for operation under ATEX IM2 conditions
perfect control with Armak Lever Control or Remote Control Valves,
if required with emergency shut off valve or with Gears or Brakes in
compliance with the EU machinery directive.
