At Schreier Industrial, we understand the importance of efficiency in an industrial setting. In manufacturing facilities, the large scale of production, storage, and all other aspects of a facility has a level of efficiency that can be easily affected by negative or positive changes in the practices implemented. Even the slightest difference in operations can change your efficiency of production with ripple effects that spread throughout your facility.


One aspect that critically affects the efficiency and quality of operations is the equipment used on the production floor and throughout your industrial workplace. For example, finding the most efficient electric motor for any format where electrical and electromechanical movement is needed is a key part of any efficiency program.


For the majority of types of electrical motors you will likely use in your facilities, you have a choice between AC or DC motor types. These two motor formats each have their own benefits and specific uses, and sometimes the question of efficiency depends on which motor type you can choose based on its intended use.


AC Motors

AC (alternating current) motors are used widely in industrial settings, including common uses like pumps, conveyors, blowers, and fans. An AC motor relies on changing magnetic fields generating an electrical current in its circuitry. There are two most commonly used types of alternating current motors; induction and synchronous. An induction motor uses alternating speeds between the rotating magnetic field and a rotor shaft (slip) for an asynchronous current in AC rotor windings. A synchronous AC motor uses permanent magnets or current generators called salient poles. It can also use an externally generated rotor winding. The speed of any AC motor is controlled by the frequency of the current generated.


DC Motors

DC (direct current) motors also rely on electrical currents generated by magnetic fields. The difference is that DC motors have an internal device that regularly changes the direction of the current’s flow through the motor. The speed of a DC motor is changed with the voltage of the direct electrical flow. DC motors tend to be used in smaller assemblies in an industrial setting, such as power tools, battery-powered components, lift trucks, and other industrial electrical vehicles. DC motors are an older technology that can often be replaced with AC motors in modern equipment.


The selection of the most efficient electric motor in your facility will often be a form of AC motor, but that doesn’t mean a DC motor is the wrong choice for any given application. With the guidance and expertise of Schreier Industrial technicians, you can find the most efficient equipment for all areas of your production floor.
