Terminology related to electric motors can be highly confusing. There are AC and DC motors, and each category includes a variety of subcategories within it, such as high efficiency brushless DC motor, brushed DC motor, etc. Two types may be identical yet have distinct names. Even though the terminology can be confusing, everyone can benefit from knowing the differences since our environment is full of electric motors. For instance, when researching a new power tool, you may have noticed the term "brushless DC electric motor" as a critical component. What distinguishes these motors from other electric motors? How do they operate? You've come to the correct place if you have asked yourself these questions. Let's start with the fundamentals: an electric motor transforms electrical energy into mechanical energy. Alternating current (AC) and direct current (DC) are the two primary forms of electricity. Direct current motors (DC) and alternating current (AC) motors both turn electrical energy into mechanical energy. AC motors and DC motors generate a spinning magnetic field using electrical current, which rotates the motor's armature. All motors turn a magnetic field; how each motor is built differs. While DC motors can be 30% more efficient than AC motors, the former are normally more powerful. Types of Electric MotorAsynchronous Vs. Synchronous Motors When researching this subject, the terms "asynchronous" and "synchronous" are frequently used in various motor types. Here is a brief explanation of each of these motor-related terms: Asynchronous: To produce torque, the magnetic fields of the rotor and stator rotate at various rates. In asynchronous motors, the stator's magnetic field typically moves more slowly than the rotors. Synchronous: To produce torque, the magnetic fields of the rotor and stator rotate at the same pace. AC MotorsThe AC induction motor was a revolution even though other electric motors had already been created when it was created in 1887. It was created in 1887 by Nikola Tesla and was given a patent in 1888. The second industrial revolution is attributed to the beginning due to the asynchronous induction motor, which "dramatically improved energy generation efficiency and made the long-distance distribution of electricity possible." The rise of 3-phase induction motors by General Electric (GE) in 1891 helps in the advancement of AC motor technology. The three-phase squirrel cage motor, a more recent form of the induction motor, is currently the most used AC motor type. So, this is the AC motor we're referring to when comparing motors to AC motors. DC MotorsA DC motor utilizes direct current to generate a magnetic field that transforms electrical energy into mechanical energy. A magnetic field is produced in the stator of a DC motor when it is energized. Magnets over the rotor are drawn to and drawn away by the field, which revolves around the rotor. The commutator, connected to brushes and the power source, transfers current to the motor's wire windings to keep the rotor turning continuously. If you are looking for the best brushless DC motor manufacturer, look no further than BMC Motor. How An AC Induction Motor WorksAC travels to the stator of a squirrel cage motor. The stator remains constant, while the magnetic field generated by the current fluctuates in response to the frequency of the AC power. The interplay of the magnetic fields on the stator causes the motor's rotor to revolve, generating torque. The magnetic field produces a current into the rotor. ConclusionOne method that more and more of our everyday products are being powered by direct current (DC) electricity is the switch from AC motors to motors powered by DC electricity. It is becoming more evident that we are in the midst of an electrical revolution as more appliances and building systems are powered by DC energy.
