Reversible compressed air motors
type MUD (page 02, fig. 2)
For type MUD motors, it is also possible for a speed throttle or silencer to be connected.
Note:
In type MUD motors, the
waste air is divided approx. 2/3 via the exhaust connection and 1/3 via the non-pressurised side.
Clockwise | counter-clockwise compressed air motors
type MR, ML (page 03, fig. 3)
Clockwise | counter-clockwise compressed air motors
type MRD, MLD (page 03, fig. 4)
If the motor is operated with a speed throttle or silencer, then this is fitted to the exhaust connection of the motor.
The air intake not required in this case is sealed in the factory.
Note:
it is
not
possible to changeover from counter-
clockwise to clockwise respectively from clockwise to counter-clockwise!
Motors with adherence-actuated | friction brake
type MUB
Control of the adherence-actuated brake,
construction series MUB, MUBZ (page 03, fig. 5)
The integrated adherence-actuated brake is triggered directly by the motor working air at the valid operating
pressure.
Control of the friction brake,
construction series MUB 300 – 600 (page 03, fig. 6)
The integrated friction brake is controlled by a separate control line. Here the spring-loaded single-disk brake must be
vented with at least 4.8 bar pressure to open the brake, i. e. the brake is activated when no pressure is applied.
Stall-proof | not stall-proof motors
Stall-proof motors
Stall-proof motors can be operated down to a standstill, i. e. no damage is caused to motor and gear when the motor is
stopped while running and when under pressure.
Not stall-proof motors – especially low speeds
These motors cannot be operated until standstill, i. e. only up to the max. stated torque. To ensure that the permitted
torque is not exceeded, we recommend fitting an overload clutch / torque limiter. Please consult the
technical data
for
the tolerable torques.
Maintenance
We recommend maintenance after 12 months or 500 operating hours to guarantee a long service life for the motor.
The maintenance intervals should be shortened for extreme operating conditions. It is advisable for maintenance to be
carried out by the manufacturer’s service technicians. If you proceed with maintenance yourself, the planetary gears,
needle bearings and motor seals must be lubricated with a suitable grease (see lubricants). Please note that a long
service life of the lamella is not guaranteed when the compressed air is totally dry.
Warning
The motor lamellae contain PTFE. Please comply with the normal health and safety recommen dations for these mate-
rials. Avoid open flames to prevent any ignition/fumes forming from particles detached from the lamellae. Fumes
caused by PTFE particles can cause allergic reactions under certain conditions.
Important
After you have performed any maintenance work on the motor, check that it will work properly. To do so, drip 2 – 3
drops of oil in the air intake and let the motor run for a few seconds in idle mode.
Guarantee
The manufacturer grants a 12 months guarantee on material and design faults for compressed-air motors used in
single-shift operation. Damage caused by wear, overload or improper handling and by failure to comply with the
instructions is not covered by the guarantee.
Complaints can only be dealt with if the motor is sent
undismantled
to the manufacturer and only if original parts were
used during any maintenance work.
