Electric motor is able to combine a magnetic field interaction force

The electric motor is a machine that is able to combine in itself the force of interaction of magnetic fields that interact in the induction of a central axis in which it moves causing force and speed.

The electric motor that powers the cars is based on phenomena of magnetism for direct current. The electric motor basically consists of a set of parts that are mounted on a housing that is metal. Practically, almost all electric motors have the same parts and will only change according to the size of the electric motor.

An electric motor consists of: field coils, which usually stays attached to a housing on the inside, this coil can be a magnet or an electromagnet. The inductance is a very important part in the electric motor because it is in the central axis of the electric motor and as the name says it is induced to rotate motivated by a relation of the magnetic fields of the coil.


When rotating, by means of the electric current, the field coil will generate in a magnetic field that is around the winding and in reason of the current that circulates in the same.

Electric motor presents problems in a very common way

As it is a machine, the electric motor presents very common problems! These problems may or may not be repaired, but there are cases where the fault is not located in the electric motor, such as when the fault is in the electric control or the starting capacitor.

When the electric motor does not turn, with the help of a multimeter it will be necessary to analyze if the power supply that the electric motor needs to function is being received correctly.

If the electric motor is just jumping and unable to rotate, the electric motor being single-phase, the multimeter should be used to check if the electric motor capacitor has not burned or if it is receiving voltage below what it needs to run. If the electric motor is three-phase, using the multimeter also will have to analyze if a phase is not missing, or if the power circuit burned when forcing the fuse. If this has happened it is time to replace the fuse and find out what motivated this burning. https://www.mrosupply.com/hydraulics-and-pneumatics/hose-reels/2516634_ez-sh-3100_coxreels/

Electric motor bearings

Electric motor bearings must be lubricated to prevent metallic contact between the rollers

The electric motor bearings must be lubricated in a way that prevents metallic contact between the rollers and serves to protect the bearings against corrosion and wear.

Due to mechanical aging and mechanical work, the properties of the lubricants may suffer from contamination and it is for this reason that they should be changed periodically or completed.

Lubricants from the electric motor can not operate at temperatures above 40 degrees because this impacts on the life of the ball bearing in continuous operation, since the bearing can last from 3 to 4 years as long as the temperature does not exceed 40 degrees, Because if it increases 10 degrees, the useful life diminishes in 50%.

Effective lubrication of the electric motor makes the electric motor improve its performance, it avoids temperature rise as this impairs the life of all the components of the electric motor. Mineral grease is the most used in the lubrication of the motor bearings electric. Coxreels P-LP-350
