Electric Motors

Electric motors are devices that convert electrical energy into mechanical energy. They are commonly used in a wide range of applications, from household appliances to industrial machinery, and are essential components in many modern technologies.

The basic principle behind an electric motor is simple. It consists of a magnetic field and a conductor. When a current is passed through the conductor, it experiences a force due to the interaction between the magnetic field and the electric charge. The direction of the force depends on the direction of the current and the orientation of the magnetic field.

There are two main types of electric motors: AC (alternating current) motors and DC (direct current) motors. AC motors are typically used in applications where constant speed is required, while DC motors are used in applications where variable speed is required.

AC motors operate by changing the direction of the current flowing through the windings of the motor, causing the magnetic field to rotate. This rotation creates a torque on the rotor, which causes it to turn. AC motors are typically used in household appliances, such as fans and refrigerators, as well as in industrial applications, such as pumps and compressors.

DC motors operate by applying a voltage to the motor, causing the current to flow through the windings of the motor. This creates a magnetic field, which interacts with the permanent magnets on the rotor, causing it to turn. DC motors are typically used in applications where variable speed is required, such as in electric vehicles and power tools.

Electric motors come in a wide range of sizes and power ratings, from small motors used in household appliances to large motors used in industrial machinery. They are also used in a variety of applications, including robotics, automation, and renewable energy systems.

In recent years, electric motors have become increasingly important due to their role in the transition to clean energy. Electric motors are used in electric vehicles, wind turbines, and solar panels, making them key components in the transition to a low-carbon economy. As technology continues to improve, electric motors are expected to become even more efficient and versatile, driving innovation and growth in a wide range of industries.

Electric Motors

An electric motor is a machine capable of converting electrical energy into mechanical energy. The induction motor is the most widely used type of motor because it combines all the advantages offered by electrical energy such as low cost, ease of supply and distribution, clean handling, and simple controls – together with those of simple construction and its great versatility to be adapted to wide ranges of loads and improved efficiencies. The most common types of electric motors are:

Direct current motors: These motors are quite expensive requiring a direct current source or a converting device to convert normal alternating current into direct current. They are capable of operating with adjustable speeds over a wide range and are perfectly suited for accurate and flexible speed control. Therefore, their use is restricted to special applications where these requirements compensate for the much higher installation and maintenance costs.
Alternating current motors: These are the most frequently used motors because electrical power is normally supplied as alternating current. The most common types are:
- Synchronous motors: synchronous motors are three-phase AC motors that run at a fixed speed, without slip, and are generally applied for large outputs (due to their relatively high costs in smaller frame sizes).
- Induction motor: these motors generally run at a constant speed which changes slightly when mechanical loads are applied to the motor shaft. Due to its simplicity, robustness, and low cost, this type of motor is the most widely used and, in practical terms, is quite suitable for almost all types of machines. Currently, it is possible to control the speed of induction motors with frequency inverters.

Electric motors are so much a part of everyday life that we seldom give them a second thought. When we switch on an electric drill, for example, we confidently expect it to run rapidly up to the correct speed and we do not question how it knows what pace to run, or how it is that once enough energy has been drawn from the supply to bring it up to speed, the power drawn falls to a very low level.

When we put the drill to work it draws more power, and when we finish the power drawn from the mains reduces automatically, without intervention on our part.

The humble motor, consisting of nothing more than an arrangement
of copper coils and steel laminations, is rather a clever energy converter, which warrants serious consideration. By gaining a basic understanding of how the motor works, we will be able to appreciate its potential and its limitations, and (in later chapters) see how the addition of external electronic controls can further enhance its already remarkable performance.

Mechanism of Electric Motors

This chapter deals with the basic mechanisms of motor operation, so
readers familiar with magnetic Xux, magnetic and electric circuits, torque, and motional e.m.f can probably afford to skim over much of it. In the course of the discussion, however, several very important general principles and guidelines emerge.

Nearly all motors exploit the force which is exerted on a current-carrying conductor placed in a magnetic Weld. The force can be demonstrated by placing a bar magnet near a wire carrying current, but anyone trying the experiment will probably be disappointed to discover how feeble the force is, and will doubtless be left wondering how such an unpromising effect can be used to make effective motors.

We will see that in order to make the most of the mechanism, we need
to arrange a very strong magnetic Weld, and make it interact with many
conductors, each carrying as much current as possible. We will also see
later that although the magnetic Weld (or ‘excitation’) is essential to the
working of the motor, it acts only as a catalyst and all of the mechanical
output power comes from the electrical supply to the conductors on
which the force is developed.

Energy in Electric Motor Works

Energy in Electric Motors

It will emerge later that in some motors the parts of the machine responsible for the excitation and the energy-converting functions are distinct and self-evident. In the d.c. motor, for example, the excitation is provided either by permanent magnets or by Weld coils wrapped around clearly defined projecting Weld poles on the stationary part, while the conductors on which force is developed are on the rotor and supplied with current via sliding brushes.

In many motors, however, there is no such clear-cut physical distinction between the ‘excitation’ and the ‘energy-converting’ parts of the machine, and a single stationary winding serves both purposes. Nevertheless, we will find that identifying and separating the excitation and energy-converting functions are always helpful in understanding how motors of all types operate.

Operation Principle of Electric Motors

A large percentage of AC motors are induction motors. This implies that there is no current supplied to the rotating coils (rotor windings). These coils are closed loops that have large currents induced in them. Three-phase currents flowing in the stator windings lead to establishing a rotating magnetic field in the air gap. This magnetic field continuously pulsates across the air gap and into the rotor. This is a single-phase representation of windings and current flow.

As magnetic flux cuts across the rotor bars, a voltage is induced in them, much as a voltage is induced in the secondary winding of a transformer. Because the rotor bars are part of a closed circuit (including the end rings), a current circulates in them. The rotor current in turn produces a
magnetic field that interacts with the magnetic field of the stator. Since this field is rotating and magnetically interlocked with the rotor, the rotor is dragged around with the stator field.

Wound Rotor Electric Motor Types

Wound-rotor motors — Although the squirrel-cage induction motor is relatively inflexible about speed and torque characteristics, a special wound-rotor version has controllable speed and torque. The application of wound-rotor motors is markedly different from squirrel-cage motors because of the accessibility of the rotor circuit. Various performance characteristics can be obtained by inserting different values of resistance in the rotor circuit.

Wound rotor motors are generally started with secondary resistance in the rotor circuit. This resistance is sequentially reduced to permit the motor to come up to speed. Thus the motor can develop substantial torque while limiting the locked rotor current.

The secondary resistance can be designed for continuous service to dissipate heat produced by continuous operation at reduced speed, frequent acceleration, or acceleration with a large inertia load. External resistance gives the motor a characteristic that results in a large drop in rpm for a fairly small change in load. Reduced speed is provided down to about 50%, rated speed, but efficiency is low.
