Electric Motor Thrust Load

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

Electric motor thrust load.

4 3 phase high thrust motors. Thrust washers may be used to move it a little if there is space for the washers i made a different washer from 16 gauge steel sheet to fit on the end of the spool. Normal thrust loads can be determined from tables based on the motor s speed and horsepower rating. There are also other factors which greatly affect the performance of electric motors such as low resistance dirt moisture over current and vibrations.

The contacts on my motor now close and the motor runs. Most of the electric motor failures occur at the start up. Depending on where the bearing is being used it may see all radial loading all thrust loading or a combination of both. High thrust is a multiple of normal thrust such as 175 250 and 300.

In this case most of the load comes from the tension in. Normal thrust c and p base. 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.

Bearings typically have to deal with two kinds of loading radial and thrust. This motor has the advantage of being applied to turbine sewage inline pumps or aerator drives. Franklin electric 4 encapsulated submersible high thrust motors built in iso 9001 14001 certified facilities for outstanding performance in 4 or larger water wells. Be sure the rotor is properly centered end to end in the motor.

The larger and heavier your boat the more thrust you ll need to achieve satisfactory results. Vertical motors are classified as normal thrust in line thrust or high thrust. It has extra thrust capacity high radial load and upthrust capacity. 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.

Electric motors should be installed very carefully and should be looked after at regular intervals. Read get your bearings. Trolling motor thrust guide thrust. 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.

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. Thrust measured in pounds lbs is the standard measure of how powerful a motor is. Arguably the most important consideration when you are looking for the right trolling motor is how much thrust your boat will need.
