When it comes to electric motors, there are countless variations available to choose from. The majority of miniature electric motors either use alternating current (AC) or direct current (DC). On top of that, motors not only range in different shapes, sizes and power levels, but can also come in brushless, brushed, permanent magnet, or synchronous designs. All of these variations mean there is a fantastic choice of motors to choose from; therefore, allowing you to find the perfect option for the given application whether for domestic, commercial or industrial applications.
By using an alternating current, an AC Motor turns electrical energy into mechanical for use in a wide range of different applications. AC motors have a wide range of advantages, including needing minimal power during start-up and offering the ability to control acceleration allowing for continuous and reliable speeds. AC motors also do not require brushes so giving additional durability compared to brushed DC motors. AC motors are generally found in applications that need steady and consistent levels of power, such as conveyors.
AC motors can be split into two main categories - synchronous or induction.
A DC motor, short for Direct Current motor, is an electrical device that converts direct current electrical energy into mechanical power. It operates based on the principle of Lorentz force, where the interaction between the magnetic field and the electric current produces rotational motion.
A stepping motor, also known as a stepper motor, is a type of electric motor that converts electrical pulses into discrete mechanical movements or steps. Unlike other types of motors that rotate continuously, stepping motors move in precise increments or steps, making them well-suited for applications that require precise position control.
Stepping motors consist of a rotor with teeth or a magnetized structure and a stator with coils or electromagnets. The stator windings are energized sequentially in a controlled manner, generating a magnetic field that interacts with the rotor. By controlling the sequence and timing of the electrical pulses applied to the windings, the rotor moves step by step, either in a clockwise or counterclockwise direction.
Today in Linquip, we’re going to discuss everything about DC motors, their types, and applications. As you may know, a DC motor or a direct connection motor is referred to as any type of rotary electric motors that converts direct electrical energy into mechanical energy. There are four main types of DC motor, all of which are used for different applications. If you want to know everything about a DC motor, DC motor types, and their utilizations.

What is a DC Motor?It’s interesting to know that DC motors are everywhere. Unlike its bizarre name, direct connection motors are everywhere around us, and they’re making our lives much more comfortable. In a nutshell, any device that uses electricity to provide various motions is doing it using DC motor types.
Now that you know what a direct connection motor is let’s dive deeper into the concept and discuss the types of direct connection motors and their application in the industrial field.
How Many Types of DC Motor Are There?There are four main types of direct connection motors:
If you want to understand how direct connection motors work and what utilizations they have, you need to get familiar with their different types.
The permanent magnet motors work by a permanent magnet to make a field flux. A PM direct connection motor does not have a field winding on the stator frame. Instead, it uses permanent magnets to provide a magnetic field against which the rotor field interacts to produce torque.
This type of direct connection motor makes excellent starting torque, and it has good speed regulation.
In the series DC motors or series wound DC motors, the entire armature current flows through the field winding. Usually, this DC motor type creates a large amount of starting torque, but it can’t regulate speed, and even running with no load can damage it. Therefore, these limitations make series DC motors, not a good option for variable speed drive applications.

See also:Shunt DC motors are a type of direct connection motors in which the shunt field winding is only parallel to the armature winding and not the series field winding. Shunt DC motors are also known as compound wound DC motors. Shunt DC motors provide excellent speed regulation, as the shunt field can be excited separately from the armature windings. This feature of shunt direct connection motors provides simplified reversing controls.

Compound DC motors or compound wound motors have both series and shunt field windings. These types of motors offer good starting torque, but they may have control problems in variable speed drive applications. These motors can be connected to two arrangements: cumulatively and differentially. The cumulative type connects the series field to aid the shunt field, providing higher starting torque but less speed regulation. The differential type has good speed regulation and usually operates at a constant speed.
Various DC Motor ApplicationsIn general, DC motors are used as variable speed drives and for the applications in which sever, torque variations occur. Now that you’re familiar with different DC motor types let’s get through their usages and applications.
Series DC motors are generally used where high starting torque is required, and speed variations are possible. These types of direct connection motors are, for instance, used in the traction system, cranes, air compressors, vacuum cleaners, sewing machines, etc.
Shunt DC motors are used for applications where you need constant speed, and the starting conditions are not severe. The shunt direct connection motors applications are in lathe machines, centrifugal pumps, fans, blowers, conveyors, lifts, waving machines, spinning machines, etc.
Compound wound motors are usually used where you need higher starting torque and relatively constant speed. The compound DC motors applications are in presses, shears, conveyors, elevators, rolling mills, heavy planners, etc.
What Are the Main Parts of a DC Motor?DC motors are composed of the following components: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes. Many of its parts are similar to those in AC motors, but there are a few differences.
What are the Advantages of DC Motors?Comparing with the AC motors that converts alternating current into mechanical power, DC motors have some advantages you might want to consider.
Generally, direct connection motors have higher starting torque than alternating current ones. This feature makes it easier to get things moving. The only problem of this feature is that you can’t start them unless they are under a load. If a DC motor doesn’t have a load to start, it can burn out fast.
The other advantage of various DC motor types is that they generate a speed-torque curve that’s more linear than the AC motors. This feature is actually due to the curve plotted between the torque and the motor’s speed, which explains the relationship between how fast the motor spins and how much torque it can generate.
The ability to control the speed is the other upper hand of direct connection motors. If you’re working with heavy load systems, the ability to control the speed becomes very crucial, and it determines whether you’ll end up with a successful job or a burned out motor. Therefore, DC motors are ideal for any job needing constant low-speed torque or variable torque.
Another important point to consider is that DC motors are easier to install compared to the AC motors. They also need less maintenance and are easier to repair. If your industrial types of equipment are set up to use DC motors, replacing a broken one with a DC motor is quick and easy. While replacing it with an AC motor will force you to redesign the whole motor circuit.
In this article, we went through all the important points about direct connection motors. Different DC motor types offer you various applications, and you need to choose the ones which fit the most with your requirements.
