Electric Motor Thrust Load

The bearings in the electric motor and the pulley pictured above face only a radial load.

Electric motor thrust load.

Arguably the most important consideration when you are looking for the right trolling motor is how much thrust your boat will need. Rolling element bearings in electric motors support and locate the rotor maintain a small and consistent air gap between the rotor and stator and transfer loads from the shaft to the motor frame. Most of them are caused by the over heating of motor. Bearings typically have to deal with two kinds of loading radial and thrust.

Vertical motors are classified as normal thrust in line thrust or high thrust. Depending on where the bearing is being used it may see all radial loading all thrust loading or a combination of both. This motor has the advantage of being applied to turbine sewage inline pumps or aerator drives. The larger and heavier your boat the more thrust you ll need to achieve satisfactory results.

The contacts on my motor now close and the motor runs. Electric motors should be installed very carefully and should be looked after at regular intervals. Electric motor lubrication 101 as an example of determining axial thrust load capacity consider a 200 hp 150 kw 1 750 rpm horizontal motor with a rotor weighing 800 lb 360 kg to be supported by the 6318 drive end bearing that is fixed axially locked in its housing. Franklin electric 4 encapsulated submersible motors built in iso 9001 certified facilities for outstanding performance in 4 or larger water wells.

Be sure the rotor is properly centered end to end in the motor. High thrust is a multiple of normal thrust such as 175 250 and 300. However the basic design has many advantages. Thrust measured in pounds lbs is the standard measure of how powerful a motor is.

The single phase high thrust 3 wire motor has been designed for highest achievable starting torque and shaft power from 1 phase power supplies in combination with a 6500 n thrust. Normal thrust loads can be determined from tables based on the motor s speed and horsepower rating. Franklin electric 4 encapsulated submersible high thrust motors built in iso 9001 14001 certified facilities for outstanding performance in 4 or larger water wells. Trolling motor thrust guide thrust.

There are also other factors which greatly affect the performance of electric motors such as low resistance dirt moisture over current and vibrations. Most of the electric motor failures occur at the start up. Read get your bearings. The 3 phase motor offers maximum life and highest efficiency under various load conditions in combination with a 6500 n thrust bearing.

This type of motor is designed for the chemical industry as defined in nema mg1 18 620. 4 3 phase high thrust motors. Normal thrust c and p base.
