Horsepower Information for Electric Motors
1. 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 2.5" to 3.0" motor pulley for a recommended auger speed of 550
to 650 R.P.M. Motor pulley not furnished. Excessive wear will result if auger speed is in
excess of 700 R.P.M. and auger load up will occur if auger speed is less than 500 R.P.M.
or flow gate is required.
2. Auger speeds in excess of 750 R.P.M. should be avoided as excessive wear will result.
Auger speed below 450 R.P.M. 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.
This Chart is a suggested horsepower requirement for standard Utility Augers.
Electrical controls and wiring should be installed by a qualified electrician. The motor
disconnect switches and conductor cables should comply with the National Electrical
code any local codes which apply. Motor starting control stations be located so that the
operator can see that all personnel are clear of the equipment.
