2.5 MATCHING MOTOR OUTPUT (SPEED)
TO LOAD – OIL PUMP/MOTOR LOCATION
It is recommended T30-M Motors be installed to
operate at an RPM between 1200-1750 RPM.
Where possible, a hand held tachometer
should be used to double-check Motor/pump
output speeds.
Motor supply pressure should be set at the
minimum pressure required
to insure the
Motor runs the speed/load required by the
pump application.
Depending on where indicated/monitored, oil
pressure may not indicate excessive motor
speed since an oil bypass (relief valve) may
reduce this to a indicate a “normal” oil
pressure reading by the operator.
Oil Pump discharge pressure (taken at the oil
pump discharge port) is the best indicator of
pump speed. Follow the pump manufacturer’s
recommendations.
Do not apply or select the maximum Motor supply
pressure by default, (e.g. “same as” fuel gas pressure
or starting air pressure on the package). Motor speed
& output must account for:
Varying starting or fuel gas pressures.
Varying oil pump models, oil viscosity, oil
temperatures (loads).
Varying site conditions (temperatures, etc…).
Varying oil pressure & cycle times required.
2.6 ADJUSTING MOTOR OUTPUT SPEED
Set multi-meter to measure frequency (Hz).
Connect the two multi-meter leads to the
speed pick-up connector attached to the air
motor.
To identify the speed on the multi-meter,
multiply the frequency times 3 as shown on
the tag affixed to the air motor.
Apply the supply pressure to the motor and
slowly increase the pressure until the desired
output speed is achieved. DO NOT EXCEED
1750 RPM.
NOTE
Motor over-speed:
Where motor & pump output
pressure or RPM, exceed that needed for an
application:
Reducing Motor supply pressure;
or
Increasing size of oil pump supply/discharge lines,
will correct this condition.
3.0 MOTOR OPERATION
WARNING
Do not operate the TDI

Motor at
dynamic supply pressures greater than the pressure
rating on the nameplate. This dynamic pressure is
measured at Motor inlet while Motor is running.
Static (non-flowing) supply pressure will
always be higher than the operating (dynamic)
pressure. The maximum pressure limit (proof
pressure) that the TDI

Motor
housings may be subjected to is 600 PSIG
(42 BAR).
Where system static pressure may exceed the
600 PSIG (42 BAR) limit, in addition to
pressure reducing device, a pressure relief
valve (set below 600 PSIG [42 BAR], should
be used.
