PURPOSE OF AN ELECTRIC MOTOR
An electric motor is a device for converting electrical power into mechanical power. An electric motor will try
to deliver the required power even at the risk of self-destruction. Therefore, an electric motor must be protected from self-destruction. Motors may be ruined by physical damage to the windings but, usually, the enemy of a motor is excessive heat in the windings. Overheating breaks down the thin varnishlike insulation on the windings. When the insulation fails, the motor fails. Overheating is the result of excessive current flow or inadequate ventilation. Accumulation of dust and dirt on and in the motor can reduce ventilation and heat removal.
MOTOR PARTS
Many types of electric motors are used for agricultural applications, and they are not all alike. However,
all motors have some basic essential parts, Figure 16-1. The frame of the motor holds all the parts in place, and provides a means of mounting the motor to machinery. The frame also conducts heat produced within the motor to the surrounding air. Some motors have fins to help get rid of heat even faster. The stator is a laminated magnetic core which holds the electrical windings. Electricity flowing through these windings produces a magnetic field.
The rotor is the part that turns and, in most farm motors, has no windings, Figure 16-2. The rotor shaft
extends from one end of the motor for connection to the driven device or machine. Some motors, such as a grinder, have a shaft extending from both ends. Directcurrent (de) motors and some alternating-current (ac) motors have windings on the rotor. These are called armatures. One end of the armature has a commutator and brushes, Figure 16-3.
The bearings hold the rotating shaft to the motor frame. Different types are sleeve, roller, and ball bearings.
The choice of bearings depends upon the application and mounting position of the motor.
A fan inside the motor moves air over the windings to remove heat (part 4 in Figure 16-1). Heat is produced by the resistance of the windings: Heat = I 2 x R x t; where t = time (see Eq. 2.22). In an open motor, air is drawn in at one end, moved over the windings, and blown out the other end. For a totally enclosed motor,
the air picks up heat from the windings and takes it to the frame, where it gets to the outside by conduction
