PNEG-195 4" Utility and Bulk Tank Auger 15
5. Electric Motor Drives
Suggested horsepower is listed in below Chart . 1750 RPM electric motors and controls shall be installed
by a qualified electrician and must meet the standards set by the National Electrical Code and all local and
state codes. Reset and motor starting controls shall be located where the operator has unrestricted access
to the controls.
Magnetic starter should be used for the protection and the motors. This is to assure the operator of
accidental restart caused by power interruption, conductor fault, low voltage, circuit interruption or thermal
overload protection, make sure this type motor has a manual reset.
Horsepower Information for Electric Motor Drive
This chart is a suggested horsepower requirement for standard 4" Utility Augers.
Horsepower recommendations are for augering reasonably dry grain at different angles. Grain with 15%
moisture and above may require more horsepower if maximum capacity is to be maintained. Use a
2-1/2'' to 3'' motor pulley for a recommended auger speed of 550 RPM to 650 RPM. Motor pulley not
furnished. Excessive wear will result if auger speed is in excess of 700 RPM and auger load up will occur
if auger speed is less than 500 RPM or flow gate is required.
Auger speeds in excess of 750 RPM should be avoided as excessive wear will result. Auger speed below
450 RPM require a flow control to restrict intake to the auger. High torque is required to turn the flighting
if it is permitted to “load up” at low speed and damage to the auger can result. An optional control gate is
available for this purpose.

Disconnect power before resetting motor overloads. Make certain electric motors
are grounded.
