Electricity powers most appliances that are used in daily life from toothbrushes to the aerospace industry. Motor manufacturers create these motors to generate power by converting the electrical energy that is created by winding currents and magnetic fields to mechanical energy that powers just about everything we use today.
Whether you make refrigerators, air conditioners, hard drives, automatic car windows or a multitude of other devices, you will ensure the quality of your product if you are sourcing from a certified electric motor manufacturer.
They work closely with customers to create an optimal solution to their needs. An electric motor parts manufacturer can modify existing motors or create a completely new design. They will also integrate different systems for smoother operation. You will find a wide variety of uses from medical equipment and the food industry to power plant instrumentation and telecommunications.
The Benefits of Electric Motors
Electric motor manufacturers provide engines with all the benefits that put these motors far above other types of motors in several ways. A few, but not all, of the benefits are:
- The simplicity of design created by an electric motor manufacturer provides low-cost energy for a huge variety of domestic and commercial applications where an alternating current (AC) power line is nearby.
- Electric motors are reliable. They require minimum maintenance during their long operational lifetime, which may last up to 10 years without replacing bearings. This adds to their cost-effectiveness.
- Harsh environments such as dust, dirt and chemicals that are found in agricultural environments do not hinder the effectiveness of electric motors. Electric motors are considered 50 to 95 percent more efficient than diesel engines and three times more efficient than petrol engines.
What Is the Difference Between an AC and a DC Electric Motor?
Alternating current periodically and consistently changes direction as well as its magnitude. Most domestic and commercial appliances and tools are made by an AC motor manufacturer. Direct current (DC) flows in only one direction. The most common example is an electrochemical cell.
Alternating current can be changed to DC by a rectifier. Direct current may be changed to AC by an inverter.
A few examples of AC motors are:
- Induction motors that are strong and long-lasting used for pumps, newer diesel trains and many industrial applications
- Synchronous motors that supply a steady speed such as for a clock
- Shaded-pole motors that have strong torque for appliances and fans
- Universal motors that can use both AC and DC for appliances and hand-held power tools
DC motors were the first kind of electric motor and are up to 80 percent efficient. They have strong torque and can work efficiently at variable speeds. A few examples of DC motors are:
Brushed motors are named after the little metal fibers that transfer current to the other side of the motor. The first ones were used on streetcars. It’s easy to control the speed, but they tend to wear out. There are several types of brushed motors including:
- Series wound
- Cumulative and differentially compounded
- Permanent magnet
- Separately excited
- Pancake motor
Electric motors not only power the everyday item, but they are also integral to the manufacturing process of just about every product produced in modern factories today, even those who manufacture electric motors. Today, more than 700 million electric motors of various sizes are operating around the world.
In the past, electric motors used a lot of power, but fortunately, today the performance and precision of the motors along with better electronics and cheaper microprocessors, the amount of power required is greatly reduced. This means the adjustable speed drive (ASD) system that adjusts the frequency and voltage supply to vary the torque and speed of AC motors is totally transformed.
