General
IRA worm and helical-worm speed reducers and gearmotors adapt
the speed of an electric motor to the driven machine.
Selection depends on motor power (P) expressed in hp and on
the required speed (n) in rpm.
Output torque of the driven system can be calculated using the
following formulas, based on reducer efficiency:
T (in.lbs.) =
P x 63025 x eff.
n

Selection Example
A foot mounted IRA worm gearmotor is required to operate a non-uniformly fed assembly conveyor from 38 to 6 rpm, 8-10 hours
per day. The output shaft will be chain/sprocket connected to the conveyor shaft in a 3:1 ratio and a 3.5" radius sprocket mounted
mid-shaft. The conveyor will require at least 0.51 hp at the maximum rpm of the range. The jobsite power supply is 3/230 VAC and
speed control with start/stop push-buttons and speed knob on the controller enclosure. The enclosure requirement for the site is
NEMA 12. Referencing the motor fan cover guard, the reducer output shaft should be at the left, the controller should be at the
right, and the speed knob should be at the upper side on the control enclosure. Final mounting will be ceiling mount.
Step 1...
The closest gearmotor hp is a 0.75 HP unit and this unit @ 37 rpm 60 Hz has an output of 0.55 hp.
(944 inch lbs torque @37 RPM)
Step 2...
The ratio that will more closely provide the desired speed range is 45:1.

Space heaters are recommended for gearmotors installed in
damp locations to prevent condensation on the motor windings when the motor is not operating. Leads are brought to the
standard motor conduit box. Space heater voltage (115, 230,
460 volts) must be specified when order is entered. Available
in gearmotors > 3/4 hp.
M9 Thermal Protection - Thermostats
This protection uses a bi-metal disc thermostat, embedded
in the motor winding, connected into the holding circuit of
the motor starter. The sensor opens the control circuit, shutting down the motor on over temperature. Thermostats give
protection for running overload, abnormally high ambient,
voltage unbalance, high or low voltage, and ventilation failure.
Thermostats will not give protection for locked rotor, starting
overload, and single phasing.

Overhung Load
Type IRA
Overhung Load
When a sprocket, sheave, pulley, or pinion is mounted on the
take-off shaft of a reducer, it is necessary to calculate the
overhung load. This calculated load must be compared with
the gearbox capacity listed to make sure the gearbox will not
be overloaded. To calculate the overhung load you need to
know the torque or horsepower at the take-off shaft and the
location along the shaft at which the load is applied.
Where:
OHL = Overhung load (pounds)
T = Torque (in. lbs.)
r = Radius of driving member (in.)
hp = Horsepower
+$RIVETYPEFACTOR
LLF = Load location factor

IntelliGear® Plus
SERIES
Variable Speed Gearmotors
General Information
1 - General Information
1.1 - General operating principle
The IntelliGear Plus variable speed gearmotor is a combination of a 3-phase induction motor and an integrated
open loop vector variable speed drive. The motor can be combined with many gear types from Emerson Power
Transmission’s range.
In the standard product version, the integrated drive does not require any connection other than the power supply.
The options may be used to broaden the application range of the IntelliGear Plus motor. Based on the advanced
technology of the IGBT power module, very high efficiency and reduced noise levels are achieved.
