The basic operation of the motor is as follows:
Pressurized air or natural gas is admitted to the motor
via the inlet port. The air expands through the two-
stage turbine, which produces shaft rotation and motor
output.
Upon a successful engine start (or cycle), turn the air
off to the motor immediately. Minimizing the time the
motor is operating, especially unloaded, will maximize
motor life
IMPORTANT
To attain maximum product life, it is important to
properly match the motor inlet supply pressure,
output and motor speed to required load.
Attain (regulate) starter to the lowest possible
supply pressure required to start the engine.
Minimizing starter back pressure will extend
the life of air motor. Back pressure should not
exceed 15 psig.
1.3 PRODUCT IDENTIFICATION
The identification nameplate(s) attached to motor
housing should indicate the following information:
Model
designation
P/Ns(OEM &/or aftermarket p/ns may be
present)
Serial Number (date of manufacture)
Maximum Operating (Inlet) Supply Pressure
Direction of Rotation
PART NUMBER IDENTIFICATION TABLE
TDI Part Number
Solar Part Number
T115-60034-MSL-1-90 1078362-100
T115-60G34-MSL-1-90 1078362-200
NOTE
Direction of Rotation is either left hand (LH) rotation
(CCW) or right hand (RH) rotation (CW) viewed looking
into the output (shaft) end of the motor.
CAUTION
Exceeding the
Maximum Operating Pressure
rating
shown on starter nameplate may result in damage
to the motor or damage to the driven equipment.
NOTE
Maximum Operating Pressure
is indicated on the
nameplate. This can (should) be measured at the
pressure check port below starter inlet port, and
dynamically
(while the motor is in operation).
IMPORTANT
Optimum
(correct)
Maximum Operating Pressure
is not
necessarily the dynamic motor supply pressure
recommended for
your
application. Starter supply
pressure regulation, by application, has been proven to
maximize the service life and reliability of the starter(s)
in most all applications. (See section 1.2)
NOTE
Proof Pressure
, if shown on the nameplate, indicates
the maximum static pressure rating at which starter
turbine motor housing(s) will not burst in operation.
1.4 STARTER MOTOR OUTPUT AND
PERFORMANCE
Please refer to specific Performance Graphs of the
model being applied which illustrate:
Starter Output
(shaft HP/Torque) over range of
dynamic
supply pressures, 0 RPM (stall) to
maximum free speed.
Air Consumption Rates
over range of
dynamic
supply pressures (consumption is constant at
dynamic
inlet pressures indicated on
performance charts).
Starter output & operating speed vary
considerably on DIFFERENT drive mediums
(e.g. air vs. methane gas).
On methane gas, starter produces significantly
more HP, at higher speeds, so inlet supply
pressures may need to be reduced (regulated)
to prevent excessive engine cranking speeds
(flame out).
In all cases, indicated performance assumes
exhaust routed to a safe location, through
system & piping that
minimizes back
pressure not to exceed 15 psig.
